Cluster Site Designation of the Southwest Louisiana National Wildlife Refuge Complex as Wetlands of International Importance under the Criteria of the Ramsar Convention
Abstract
The Ramsar Convention of 1971 is an international treaty seeking to protect, conserve and assist in the planning and management as well as wise use of the world's wetlands. Designation of Louisiana’s diverse wetland areas, specifically a cluster of National Wildlife Refuges in Southwestern Louisiana as Ramsar Wetlands of International Importance ensures a complete approach to conservation management principles that will seek to protect our valuable Louisiana wetland coastal habitats from natural and human-made threats.
The loss of Louisiana wetlands, to coastal erosion, global sea rise and historical development is a major environmental concern for the United States. These wetlands are home to endangered and threatened animal and plant species as well as habitat to thousands of migratory birds, waterfowl, fish, reptiles, mollusks and mammals. The science, academic, volunteer, political and legislative communities of the United States are working to conserve the Louisiana wetlands through a multitude of studies, projects and programs aimed at preserving, protecting, restoring as well as recognizing the value of wetlands.
The coastal zone of Louisiana has diverse wetlands, including freshwater swamps, hardwood and bottomland swamps, freshwater marshes, brackish marshes and saltwater marshes that are home to valuable natural resources, some of which are threatened by coastal erosion. Ramsar encourages listing of diverse wetland sites and in fact permits clustering of diverse sites for a single listing as a wetland of international importance.
National wildlife refuges on the coast of Louisiana are recognized and in fact protected under current law as ecosystems of importance to the country. The Southwest Louisiana National Wildlife Refuge (NWR) Complex is an established public conservation entity comprised of Cameron Prairie NWR, Sabine NWR, and Lacassine NWR. The Ramsar Convention outlines specific criteria for potential candidate wetland sites to meet for listing to the Wetlands of International Importance List and supports clustering of wetland sites.
The Ramsar Information Sheet (RIS) lists the characteristics of sites and the science that justifies any statements made regarding the qualities of the nominated wetland sites. Administrative planning and management approaches toward nominated sites are included in the RIS. The RIS provides a standardized format or data sheet for recording information about the region. Data and information collected on hydrological, biophysical, floral, faunal, social and cultural functions and values are critical elements that determine eligibility for Ramsar listing.
The Federal government as well as the Louisiana state government supports international wetland designation and are in fact established participants in the Ramsar Convention. The U.S. Fish and Wildlife Service administers the Ramsar Convention and recently announced new U.S. sites for inclusion on the listing of Wetlands of International Importance. Louisiana hosts a Ramsar site at Catahoula Lake in Rapides Parish. This site is an inland wetland, a National Wildlife Refuge and member of Ramsar since 1991. The Louisiana Coastal Authority has recently produced a report outlining the national and international importance of the Louisiana Coastal Wetlands to the global economy and security of the world.
Application of The Ramsar Convention of 1971 to Louisiana wetlands, specifically the wetlands of the coastal zone is appropriate, notably so as some of the world's more diverse wetland areas. The National Wildlife Refuges established on the Louisiana Coast offer federal and state parties an opportunity to enlist Ramsar international recognition and support in the complete planning and management effort of Louisiana's wetlands.
Designating the Louisiana Coastal Zone Wetlands, in particular, Cameron Prairie, Lacassine, and Sabine National Wildlife Refuges as a cluster site of “Wetlands of International Importance” ensures conservation, protection, and management through wise use of wildlife habitat and the wetlands’ natural resources.
Introduction
Literature Review
Wetlands
World View
Wetlands occupy about 6 percent of the land surface of the world, 2.2 billion acres. The United States contains about 274 million acres or 12 percent of the world's total wetlands. Louisiana is 36% wetlands totaling 48% of the United States’ coastal wetlands.
As the previous statistics relate, wetland research can be an immense undertaking. Even grasping the concept of global classification of landscapes is an intimidating undertaking. A leading international environmental law expert Michael Bowman surmised that the concept of wetlands is often difficult to comprehend, much less define, stressing that “This (wetlands) is a term of no great precision, either in popular or scientific parlance, and indeed in certain languages there is no single word which adequately reflects the concept”. He cites the French language as an example of the different interpretation cultures assign to words, “…the rendering in the French language text - ‘zones humides’ - conjures up a rather different image from its English counterpart.”
One author, P.J. Dugan, suggests in the article, “Wetland Conservation: a Review of Current Issues and Required Action” fifty or more different definitions of wetlands are currently in use. He cites the International Wildlife Law journal as having the broadest definition.
In 1971, the Ramsar Convention established an internationally agreed upon standard for addressing wetlands. The Convention adopted a definition addressing, “…every wet area, near wet or infrequently wet parcel of land, without particular regard to scientific nicety”.
In Ramsar, participant nations were declaring the intent to establish a multi-lateral-global mission to protect wet landscapes through a working definition of wetlands and accompanying guidelines for interpreting the wetlands’ defining characteristics. This Convention, despite language barriers, geopolitical and even geographical differences, provided a working base definition for the contracting parties to use in the establishment of national environmental management programs for wetlands. These characterizations and definitions were not developed to supercede established definitions that nations may employ. The Ramsar definition and accompanying framework for the protection of wetlands provide scientists and politicians a common base of policy with which to work, while allowing for individual determination of a working definition of wetlands. At the time of the Convention, the environmental protection movement was just beginning to blossom, making Ramsar’s early definition of wetlands a significant achievement of agreement in environmental protection.
Director General of the International Union of Concerned Nations (IUCN), delivering the keynote address at the Fourth Meeting of the Conference of the Parties in Montreux, Switzerland joked that the many and broad definitions of wetlands, “suggests that only two Conventions are really needed to cover the conservation of all the habitats in the world. The Ramsar Convention dealing with any land that can be generally termed wet, and a Drylands Convention dealing with everything else.” ,
Geopolitics can make defining wetland landscapes a difficult task. Not only must one consider the scientific definitions including soil makeup, water quality, flora types and other quantifiable and identifiable components, one must consider the cultural, social and economic value to varying cultures. In 1971, Ramsar provided this working definition for contracting parties of the Convention to use in formulation of environmental programs.
U.S. View of Wetlands Over Time
One of the earliest wetland definitions used in the United States comes from an 1890 federal government report on wetlands, General Account of the Freshwater Morasses of the United States.
The U. S. Fish and Wildlife Service (USFWS) as part of a wetland classification system for categorizing waterfowl habitat developed one of the earliest working definitions commonly referred to as Circular 39. The USFWS uses this definition for classification purposes, notably for differentiation among various wetland types for wildlife habitat categorization.
The U.S. Fish and Wildlife Service's definition and the federal regulatory wetland definition used to identify wetlands under the Clean Water Act are the two major definitions used in the United States. The U.S. Fish and Wildlife Service concept of wetlands is based upon L.M. Cowardin’s longstanding research.
The U.S. Army Corps of Engineers (COE or CORPS) uses the following regulatory definition of wetlands for developing a field method to analyze jurisdictional boundaries for regulatory purposes.
The Corps’ regulatory management policy utilizes a three-parameter test incorporated into their definition. Under this definition an area is considered a wetland only if all three conditions are present. The Corps determines wetlands to have one or more of the following three attributes,
1. “at least periodically, the land supports hydrophytes and
2. the substrate is predominantly undrained hydric soil and
3. the substrate is non-soil and is saturated with water or covered by shallow water at some time during the growing season of each year.”

The USFWS definition includes:
1. swamps
2. freshwater
3. brackish water
4. saltwater marshes
5. bogs
6. vernal pools
7. periodically inundated saltflats
8. intertidal mudflats
9. wet meadows
10. wet pastures
11. springs and seeps
12. portions of lakes, ponds, rivers and streams
13. all other areas which are periodically or permanently covered by shallow water, or dominated by hydrophytic vegetation, or in which the soils are predominantly hydric in nature.
The USFWS categorizes wetlands into two basic groups:
1. Coastal Wetlands
a. “Coastal Wetlands are found along the oceans and closely linked to estuaries where seawater and freshwater mix.
b. Grasses, sedges, and rushes that are salt tolerant take advantage of nutrients flowing into their environment once or twice daily (tides) resulting in tidal salt marshes that are exceptionally high in total production of organic matter.”
2. Inland Wetlands
a. “Inland Wetlands are found on floodplains along rivers & streams (riparian wetlands), in depressions surrounded by dry land.”
b. Potholes, basins, swamps, bayous and along margins of lakes and ponds, and any other low-lying area where groundwater intercepts the soil surface are wetland areas. Inland wetlands include marshes and wet meadows dominated by herbaceous plants and swamps dominated by shrubs and trees.”
NOAA defines coastal wetlands as “all wetlands in coastal watersheds, i.e., watersheds that drain to the ocean or to an estuary or bay”. The prolonged presence of water creates conditions favoring specially adapted plants (hydrophytes).
Wetlands vary widely because of regional and local difference in soils, topography, climate, hydrology, water chemistry, existing vegetation, and other factors, especially human disturbance. They occur in widely diverse settings ranging from coastal margins, where tides and river discharge are the primary sources of water, to high mountain valleys where rain and snowmelt are the primary sources of water. Every continent in the world except Antarctica has wetlands within its borders.
More than 220 million acres of wetlands existed in the coterminous U.S. (lower 48 states) in colonial times. Today, less than half remain (about 100 million acres). The lower 48 states contain 5% of all wetlands, while Alaska alone possesses over 200 million acres, more than twice the acreage of all other states combined, (see Tables 1, 2, 3 )
The National Wetlands Policy Forum of the U.S. Government recommended a program of no net loss of wetlands in 1988. Under this Executive Order of President George Bush, lost acreage due to development, agricultural use or degradation was to cease, while recovery by the creation of new wetlands and the restoration of any degraded wetlands would increase.

From the mid-1950s to the mid-1970s, the coterminous U.S. lost an average of 458,000 acres of wetland per year. Between the mid-1970s to the mid-1980s, the loss rate dropped to about 290,000 acres/year. Today, the annual loss rate is about 60,000 acres.
Wetland loss in the U.S. continues. Greatest losses in the U.S. occur in the Southeast in states including Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina, and South Carolina, (see Table 7). Most of these states are losing forested wetlands to agriculture, yet recent agricultural policies may be reducing this type of wetland conversion, resulting in coastal wetland loss figures increase.
Wetland Functions
An understanding of wetland functions and the underlying chemical, physical, and biological processes supporting these functions aids in the management and protection of wetlands and associated basins. Storage of flood run-off water in wetlands is associated with lakes and streams where these store floodwaters by spreading water out over a large flat area. This temporary storage of water decreases runoff velocity, reduces flood peaks, and distributes storm flows over longer periods, causing tributary and main channels to peak at different times.
Ground water and surface water, transport sediments, nutrients, trace metals, and organic materials. Wetlands can trap, precipitate, transform, recycle, and export many of these components. As a result, the water leaving the wetland can differ markedly from that water entering. Wetlands can maintain good quality water and improve degraded water. Recharge to aquifers can be especially important in areas where ground water is withdrawn for agricultural, industrial, and municipal purposes. Wetlands can provide either substantial recharge to aquifers.
Wetlands reduce shoreline erosion by stabilizing sediments and absorbing or dissipating wave energy. Beaches and shallow vegetated wetlands protect shorelines from the destructive power of storms. Wetland vegetation decreases water velocities allowing sedimentation in shallow water areas and flood-plain wetlands often building up natural levees.
Diverse functions of wetlands include providing habitat for wildlife, fish and birds, as well as protecting humans from natural disasters and providing humans with food sources. Healthy wetlands can achieve lower flood peaks for rivers, streams and bayous and, provide water during drought periods, sustain more wildlife and habitat, and provide better surface water quality than comparable watersheds with fewer wetlands. Wetlands also provide recreation areas for sport fishing, crabbing, netting, boating, eco-tourism, birding and more. Areas adjacent to wetlands also provide wildlife corridors and urban buffers within the landscape.
Wetlands serve as sources of community pride or representations of culture. “The mere existence of wetlands may be of great significance to some people. Those who have grown up in wetlands, but have moved away to a town, may have placed a high value on the wetland because it is part of their cultural heritage, even though they may never visit the wetland.”
Management of Wetlands
U.S.
The Environmental Protection Agency (EPA) oversees wetland management in the United States. EPA administers regulations established by federal law for wetland conservation, restoration, and monitoring. EPA establishes environmental standards for associated agencies to review, including the United States Army Corps of Engineers (COE/CORPS/Corps). The Corps reviews permits for discharges that affect wetlands, such as residential development, roads, and levees. The Corps also coordinates its regulatory processes with the United States Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service (NMFS) and associated state authorities.
The Corps regulates waters and wetlands under two laws. Section 10 of the Rivers and Harbors Act is the first law the Corps administered. Under this regulation, a permit is required from the Corps for any project that involves work or structures in, over or under navigable waters of the United States.
The second law is Section 404 of the Clean Water Act. “Recognizing the potential for continued or accelerated degradation of the Nation's waters, the US Congress enacted the Clean Water Act formerly known as the Federal Water Pollution Control Act (33 U.S.C. 1344).” Under this law, a permit is needed from the Corps or the discharges of dredged or fill material into any water of the United States, including wetlands. The basic premise of the program requires exploration of a practicable alternative that is less damaging to the aquatic environment or the nation's waters prior to discharge of dredged or fill material. When applying for a permit, one must show that the proposed discharge has,
1. taken steps to avoid wetland impacts where practicable
2. minimized potential impacts to wetlands
3. provided compensation for any remaining, unavoidable impacts through activities to restore or create wetlands
A permit review process is part of the regulation mechanism. Projects with potentially significant impacts usually require an individual permit. For most discharges anticipating minimal adverse effects, the Army Corps of Engineers often grants up-front general permits. The general permit may is issued on a nationwide, regional, or state basis for particular categories of activities. Minor road crossings, utility line backfill, and bedding fall under general permit regulations. Section 404(f) exempts some activities from regulation. These activities include farming, ranching, silviculture and other agricultural activities. Wetlands are identified in the field using the Corps delineation manual. “The purpose of this manual is to provide users with guidelines and methods to determine whether an area is a wetland for purposes of Section 404 of the Act.”
In 1972, the U.S. Congress enacted the Coastal Zone Management Act (CZMA). The CZMA encourages states to preserve, protect, develop, and, where possible, restore or enhance valuable natural coastal resources such as wetlands, floodplains, estuaries, beaches, dunes, barrier islands, and coral reefs, as well as the fish and wildlife using those habitats. In the CZMA, Congress declared it best for the national interest to maintain a program for the effective management, beneficial use, protection, and development of the coastal zone.
The CZMA makes federal financial assistance available to any coastal state or territory. Qualifying states must develop and implement a comprehensive coastal management program. National Oceanic and Atmospheric Administration (NOAA) is the appointed managing agency for the CZMA. The Office of Ocean and Coastal Resource Management (OCRM) administers individual state coastal zone management programs.
Currently, the OCRM oversees programs in all coastal states except Georgia, Illinois, Indiana, Minnesota, Texas, and Ohio. All of these non-participating states are currently developing coastal programs except for Illinois and Indiana.
In addition to resource protection, the CZMA specifies that coastal states may manage coastal development objectives and projects. A state with an approved program can review, comment, deny or restrict proposals not harmonious with coastal zone management programs’ missions. The CZMA does not apply to states that are not CZMA participants or have not yet received OCRM approval.
International Management of Wetlands
In 1972, international awareness of environmental issues reached a peak at the United Nations Conference on the Human Environment in Stockholm, Sweden. The Stockholm agreement birthed the United Nations Environmental Program (UNEP), designed to manage and administer the global network of environmental treaties.
From 1972 to 2000 and beyond, hundreds of nations signed on to dozens of international treaties to globally preserve natural and cultural heritage, control the trade in endangered species, protect wildlife habitat, protect migratory stocks and reduce air and ocean pollution. These agreements led to others to protect the ozone layer, to regulate the use of ocean resources and to control transboundary movements of hazardous waste and limit indiscriminate whaling.
Since the 1970s, the world community has developed an extensive body of international environmental laws addressing a wide range of topics. To date more than 1000 treaties exist.
Sovereign governments enter into international environmental agreements, treaties, and protocols for the conservation of national interests but also for the protection and conservation of cross boundary and global resources. These intergovernmental agreements are bilateral and multilateral, requiring broad acceptance to be effective.
Some examples of familiar international environmental treaties include,
• Montreal Protocol, to reduce and terminate the consumption of chemical compounds that destroy ozone in the stratosphere.
• Convention on the International Trade of Endangered Species of Fauna and Flora (CITES)
• Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal
The official name of the Ramsar treaty is, “The Convention on Wetlands of International Importance Especially as Waterfowl Habitat, adopted in Ramsar, Iran, in 1971”. The treaty is familiarly known as the Ramsar Convention , or Ramsar. The Convention has more than 130 member countries. Presently, 145 Contracting Parties to the Convention are signatories to the international treaty. One thousand four hundred thirty five (1435) wetland sites totaling 125.1 million hectares are designated for inclusion in the Ramsar List of Wetlands of International Importance.
The Convention provides guidance on preparing national policies, legislation and tools for managing wetlands in developing countries and among established nations. Through the nomination of wetland sites adhering to specific criteria, Ramsar Convention member countries designate candidate sites to add to the List of Wetlands of International Importance (Ramsar List).
“The inclusion of a site in the Ramsar List confers upon it the prestige of international recognition and obliges the government to take all steps necessary to ensure the maintenance of the ecological character of the site. Inscription on the Ramsar List acknowledges the international importance of the site.”
Beth Kruchek of Georgetown Law School says, “The United States has an obligation under the Convention on Wetlands of International Importance Especially as Waterfowl Habitat (Ramsar Convention) to promote the protection of wetland habitats within its borders.” “Wetlands are dynamic areas, open to influence from natural and human factors. In order to maintain their biological diversity and productivity (i.e., their ecological character as defined by the Convention and to permit the wise use of their resources by people, an overall agreement is essential between the various managers, owners, occupiers and other stakeholders. The management planning process provides the mechanism to achieve this agreement (Ramsar).”
Support for international management consortiums and networks is a successful management approach, “…considering the broad scope of problems/issues and diverse interests among governments, international organizations, and private sector groups, a body.” Criticism of multi-lateral international environmental organizations does exist. For example, Daniel Esty of the Yale Center for Environmental Law and Policy says, “the global environmental governance structure is inadequate for the pollution and resource challenges the world faces today.” Esty said, the entire body is “weak and performing poorly.” He concluded, “The growing recognition that a number of serious pollution control and resource management issues are inherently transboundary in their scope makes the status quo unacceptable and the need for improved global environmental governance urgent.”
Louisiana Wetlands Discussion
Wetlands Physical Situation
Louisiana is comprised of two primary geographic regions, the lowlands and the uplands. The landscape of south Louisiana is part of the Mississippi River Basin formed during the Holocene (0.01 mya to present) epoch. The lowlands of Louisiana subdivide into three major divisions.
1. Mississippi and Red River alluvial plain
2. Deltaic plain
3. Chenier plain
The Mississippi River Basin drains 41% of the contiguous United States and a portion of Canada, transporting water and sediment over an area of 1.2 million square miles, carrying alluvial sediments of the Mississippi, Red, Ouachita, and other rivers and smaller tributaries into the marshes of the coastal zone. These organically rich deposits occupy about 55% of Louisiana’s surface.
The Mississippi River originally deposited sediment along the Louisiana coast, naturally restoring wetlands and coastal marshes, building up land and constructing natural levees, all the wile replenishing coastal fisheries with nutrients and food sources. Today the river is confined within a levee system and water flow is managed through locks and control structures, which ultimately forces the overextended course of the river to deposit sediment over the edge of the continental shelf. Control of the Mississippi River’s path and associated dredging of access canals has also led to salt-water intrusion into ecologically fragile environments.
Since the turn of the last century, the U.S. Army Corps of Engineers has held the Mississippi River in its present course. This containment contributes to the current dilemma of erosion in the coastal regions. As far back as 1976, Don Moser satirically commented on the Corps’ historical planning of the Mississippi River in a Smithsonian Magazine article saying, “By now it has become clear that the Corps is more likely to be a restorer than a developer of fragile lands” .
Coastal erosion affects all regions of the United States. Average coastline recession rates of 25 feet per year are not uncommon on some barrier islands in the Southeast, and rates of 50 feet per year have occurred along the Great Lakes. Louisiana is losing coastal wetlands at an estimated at 50 square miles per year.
Without the marsh and wetlands as a buffer, some experts predict a 20-foot storm surge that might swamp New Orleans. LSU researchers believe a 1965 Hurricane Betsy-type storm hit New Orleans today, the damage would be far worse without the coast’s wetlands and barrier islands deflecting the storm surge. The barrier islands protect the coastline by breaking down waves and storm surges before they hit the coast.
Palustrine wetlands include scrub shrub, non-tidal and tidal marshes and ponds. These types of wetlands are the most common type in Louisiana. The most common palustrine wetland is the swamp or forested wetlands, which make up 59% of the wetlands in Louisiana. Coastal wetlands consist mostly of salt water or brackish water marshes and act as estuarine emergent wetlands.
Saltwater marshes, nearest to the coast and subject to regular tidal inundation, have average salinities near 16 parts per thousand (ppt). They are typically dominated by hardy salt-tolerant plant species. Freshwater marshes typically never exceed salinities greater than 2 ppt. The freshwater marsh type sustains high densities of wildlife, including migrating waterfowl.
Forested wetlands of Louisiana exist in two vegetation zones, bald cypress/tupelo swamps and bottomland hardwood forests. The near year round presence of standing water allows for the growth of aquatic plants. Forested wetlands are some of the only wooded areas untouched by agriculture, industry, and urban use.
The cheniers of coastal Louisiana are areas where coastal ridges act as the landmasses with the highest elevation along the coast. As a result, these ridges are historically known for supporting maritime forests dominated by live oaks trees. Live oak (Quericus virginianus) hammocks fill the landscape of the coastal cheniers in Cameron and Calcasieu parishes. Chenier is the French word for oak. These landmasses have an important ecological role as a temporary habitat for many migrating species. The cheniers become stopping points for migrating birds heading north crossing the Gulf of Mexico as well as the last available ground before crossing the Gulf for those heading south. These special chenier habitats for mammals and birds in coastal Louisiana are extremely important shelters for animals seeking refuge from coastal storms.
More than 1900 square miles of Louisiana’s coastal wetlands have disappeared. According to LSU’s Greg Stone of the Department of Oceanography and Coastal Sciences, Louisiana is experiencing the highest rate of coastal erosion in America, losing about 100 yards of land every 30 minutes. “That is a football field every half-hour.” In the past 250 years, 2.5 million acres of coastal prairie of southwest Louisiana have dwindled to just 200 in scattered parcels.
Coastal Louisiana has lost over 900,000 acres since the 1930s. In the 1970s, the loss rate for Louisiana’s coastal wetlands was as high as 25,600 acres per year. The current rate of loss is about 16,000 acres per year, forewarning a 320,000-acre net loss by the year 2050.
Wetland Commercial Values
Wetlands provide a variety of goods and services to humanity in direct and indirect ways. Our global natural ecosystem has been estimated at US$33 trillion, of which the value of wetland ecosystem is estimated at US$14.9 trillion (45 percent of the total).
Almost one-third of the nation's oil and gas production and the largest seafood harvest in the lower 48 states originate in the Louisiana wetlands. Additionally, Louisiana’s coastline protects one of the largest shipping and fuel production corridors in the U.S. from hurricanes and open water conditions. “Just one of Louisiana's major ports receives about a million barrels of oil every day, roughly 13 percent of the nation's foreign oil supply.”
Approximately 70% of the commercial fisheries in the United States depend on estuaries and salt marshes for nursery or spawning grounds. In 1995, the commercial fish catch totaled 4.5 million metric tons and was valued at a record $3.8 billion.
Seafood production, harvest, and associated businesses are a major sector of the U.S. economy. In 1995, Americans consumed an average of 15 pounds of seafood per person, and spent a total of $38.6 billion on seafood products.
In 1991, Louisiana’s coastal marshes produced a commercial fish and shellfish harvest amounting to 1.2 billion pounds worth $244 million. Currently, the dockside value of Louisiana's commercial seafood harvest is more than $342.7 million, not including the valuable recreational fishing industry of $944 million.
The waters of Louisiana support deep-water offshore, coastal bay, lake, bayou and marsh fishing and aquaculture industries. The shrimp fishery is Louisiana’s largest commercial fishery, accounting for over 85% of the value of the state’s edible fisheries production. The shrimp industry is based on the brown and white shrimp (Penaeus aztecus and Penaeus setiferus), harvested inshore in the spring and fall respectively, which accounts for 93 to 96% of landings by poundage.
From 1976 to 1990, 40% of Louisiana shrimp landings are in inshore state waters, 43% are in the state’s offshore waters, and 17% are in federal waters off Louisiana’s coast. White shrimp landings for the year 2000 totaled 75,864,278 pounds (34,411.8 metric tons) for a value of $152,374,346. The total take of brown shrimp for the year 2000 was 62,115,422 pounds (28,175.4 metric tons) for a value of $96,514,340. Processing industries are a source of additional employment.
From 1970 to 1990, 40% of the Gulf of Mexico shrimp landings were landed in Louisiana. The state’s shrimp industry lands about 70% of the Gulf production of small shrimp. Both absolute landings and the share of Gulf landings have increased during that period. Some scientists have hypothesized that this rise is attributable to an increase in shrimp habitat resulting from deterioration of the wetlands along coastal Louisiana. If this is the case, Louisiana catch may begin to decline within the next 15-20 years.
Oyster production in Louisiana is a $30 million dockside industry. Louisiana’s coastal waters produce an average of 13 million pounds of oysters annually, of which 60% ships to other states and countries. Eastern oyster (Crassostrea virginica) landings for the year 2000 totaled 11,513,438 pounds (5,222.5 metric tons) for a value of $24,614,159. Blue crab (Callinectes sapidus) landings for the year 2000 totaled 51,430,385 pounds (23,328.7 metric tons) for a value of $36,770,381.
Freshwater species of commercial importance include blue catfish ( Ictalurus furcatus), channel catfish (Ictalurus punctatus), flathead catfish (Pylodictis olivaris), yellow bullhead (Ameiurus natalis), bowfin (Amia calva), carp (Cyprinus carpio carpio), gar (Lepisosteus occulatus and Lepisosteus spatula), and buffalo (bigmouth-Ictiobus cypriellus and smallmouth-Ictiobus bubalus). Additionally, wetlands are habitats for fur-bearers like muskrat, beaver, and mink as well as reptiles such as alligators. The nation’s harvest of muskrat pelts alone is worth over $70 million annually. The Louisiana Nutria pelt industry is the largest producer of Nutria pelts and meat in the U.S., which at this time is providing over one million pelts per year. In 1945, trappers took 8,500 pelts.

The Coastal Wetland Planning, Protection Restoration Act of 1990, (PL-101-646, Title 111, CWPPRA), locally referred to as the Breaux Act provides authorization and funding of multi-level, federal, state and local as well as non-governmental organizations for formation of a task force to investigate ways to mitigate wetland losses. In 1998, the State of Louisiana and the CORPS, the EPA and other federal agencies charged with restoring and protecting Louisiana coastal wetlands adopted a new coastal restoration plan.
That strategic plan, Coast 2050: Toward a Sustainable Coastal Louisiana, was developed by federal, state, and local governments (Louisiana Coastal Wetlands Conservation and Restoration Task Force and Wetlands Conservation and Restoration Authority 1998).
The plan focuses wetland protection on restoring and mimicking the natural processes that originally formed coastal Louisiana. The plan sub-divides Louisiana’s coastal zone into four regions of nine hydrologic basins proposing ecosystem restoration strategies for each. Coast 2050 seeks to implement the most complex wetland program in Louisiana history.
In January 2005, Louisiana Governor Kathleen Babineaux Blanco and Lt. Gen. Carl A. Strock, Chief of Engineers with the U.S. Army Corps of Engineers, signed a partnership agreement dedicating the “…combined efforts (of government entities) towards a common goal of reversing the current trend of degradation of Louisiana’s coastal ecosystem”. In addition, Strock signed the Chief of Engineer’s report; compiled for submission to the Congress in consideration for funding of the Louisiana Coastal Area Ecosystem Restoration Study and associated projects. A January 2005 Louisiana Coastal Area (LCA) news release called the document signing, “…a historic step in the advancement of the coastal restoration blueprint toward authorization.”
Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) restoration funds administered through the Louisiana Coastal Wetlands Conservation and Restoration Task Force of the LCA totaled $334 million of federal and matching state funds in 1995. These funds are committed for coastal wetlands restoration projects in Louisiana where 34 of the 91 projects that the task force approved for construction are completed, with 15 more under construction.
In May 2005, Louisiana enrolled the state’s 200,000th acre (80937.5 hectares) of land into the federal Wetlands Reserve Program. This program is part of the 2002 U.S. Farm Bill. The Department of Agriculture (USDA) and the Natural Resources Conservation Service (NRCS) administer conservation programs targeted at farmers and agricultural operations. This voluntary program provides technical and financial assistance to eligible landowners to address wetland, wildlife habitat, soil, water, and related natural resource concerns on their properties.
Louisiana Wildlife Habitat Management
The Louisiana Division of Wildlife and Fisheries (LDWF) manages 48 Wildlife Management Areas (WMAS) in the state. The agency is responsible for overseeing property totaling more than 1.2 million acres. Five (5), state refuges exist in the Louisiana Coastal Zone, totaling over 428,000 acres. The state manages the wildlife areas with the assistance of the federal government. The LDWF manages policy, enforces laws and conducts research into coastal marsh management practices for fur, estuarine fisheries, and wildlife resources. “Properties currently administered by the Fur and Refuge Division are open for various forms of public recreation,” such as hunting, fishing, hiking, camping, birding and botanizing.
Ramsar Convention
History
The Convention on Wetlands, signed in Ramsar, Iran, in 1971, is an intergovernmental treaty providing the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources. The Convention entered into force in 1975 and as of May 2005 has 145 Contracting Parties. Ramsar is the first of the modern global intergovernmental treaty on conservation and wise use of natural resources.
Although examples of multilateral nature conservation agreements can be traced back to the turn of the century and beyond, not until the late 1960’s did the international environmentally concerned communities begin to perceive the true seriousness of the threat posed by the continuing degradation of the natural environment and the urgent need for a concerted global response.
The international environmental community adopted a substantial number of international environmental treaties from 1972 onwards. The framework for the Ramsar Wetlands Convention formed the year before Stockholm and thus “stood astride the very threshold of modern environmental law, its founding fathers unquestionably appraised of many of the key tenets of contemporary conservation philosophy”.
M.J. Bowman calls the Ramsar Convention in its original form, “…an extraordinarily simple, almost simplistic, legal instrument”. He explains that the treaty consists of twelve articles, four of which were devoted to the articulation of substantive obligations, four to institutional arrangements and other mechanisms for implementation, and four to the final clauses governing participation and the exercise of depositary functions.”
Mission and Procedures
The Convention's mission is “…the conservation and wise use of all wetlands through local, regional and national actions and international cooperation, as a contribution towards achieving sustainable development throughout the world”. The United Nations Educational Scientific and Cultural Organization (UNESCO) is the official depositary agency for the Convention.
The Ramsar Bureau administers the convention and is housed in the headquarters of The World Conservation Union (IUCN) in Gland, Switzerland, under the authority of the Conference of the Parties and the Standing Committee of the Convention.
Benefits of Ramsar
According to Ramsar when a country joins the Convention the commitment represents:
• an endorsement of the principles that the Convention represents, facilitating the development at national level of policies and actions, including legislation that helps nations to make the best possible use of their wetland resources in their quest for sustainable development;
• an opportunity for a country to make its voice heard in the principal intergovernmental forum on the conservation and wise use of wetlands;
• increased publicity and prestige for the wetlands designated for the List of Wetlands of International Importance, and hence increased possibility of support for conservation and wise use measures;
• access to the latest information and advice on application of the Convention’s internationally-accepted standards, such as criteria for identifying wetlands of international importance, guidelines on application of the wise use concept, and guidelines on management planning in wetlands;
• access to expert advice on national and site-related problems of wetland conservation and management through contacts with Ramsar Bureau personnel and consultants and through application of the Ramsar Advisory Mission mechanism when appropriate; and
• international cooperation on wetland issues and brings the possibility of support for wetland projects, either through the Convention’s own Small Grants Fund or through the Convention’s contacts with multilateral and bilateral external support agencies.
The United States ratified the Ramsar Convention on April 18, 1987. U.S. support of Ramsar has remained strong since the Convention’s inception. As recently as 1997 testimony before the U.S. Senate, head of the U.S. Ramsar Committee called funding Ramsar projects, “Prudent investments in the protection of natural ecosystems and human welfare are in the economic interest of the United States.” That same testimony stated that “…making these investments now can yield dividends for our children's future; dividends in the form of more bountiful harvests, life-saving drugs, a stable climate, and a clean environment. The Ramsar Convention funding will be particularly critical to assure the global supply of seafood and the abundance of waterfowl and other bird species. Wetland conservation through the Convention provides other, crucial ecosystem services such as carbon sequestration, which counteracts global warming, water quality enhancement, and flood damage reduction.”
Ramsar also provides opportunities for actions to increase knowledge and awareness of wetlands and their values, including:
• interchange of experience and information on wetland policy, conservation and wise use between countries preparing and/or implementing national wetland policies, or pursuing wetland conservation;
• increasing the awareness and understanding of decision-makers and the public of the full benefits and values, within the terms of wise use, of wetlands. Among these benefits and values, which can occur on or off the wetland itself, are:
• sediment and erosion control policies
• flood control maintenance of water quality and abatement of pollution,
• maintenance of surface and underground water supply,
• support for fisheries, grazing and agriculture,
• outdoor recreation and education for human society,
• provision of habitat for wildlife, especially waterfowl, and
• contribution to climatic stability
Costs of Ramsar listing are minimal. In established wetland research zones, collection and organization of data such as wetland inventories, value matrixes, habitat numbers and wildlife conditions are necessary elements in the application process. Minimal costs include time spent negotiating, commenting upon and accepting management plans, and costs associated with ongoing monitoring from an oversight agency.
The most obvious and beneficial result of listing for countries, nations, landowners, public and private, is the gained assurances about the future uses of the wetland, these being determined through the agreed management plan. Ramsar listing also places the burden on the governments of member states for ensuring the continued health of the wetland now and into the future. Additionally, Ramsar listing provides added advantage in securing funding and other assistance with management.
The Convention promotes the sustainable use of aquatic ecosystems, allowing communities to gain economic benefits from these areas while maintaining the ecosystems’ viability. Ramsar designations have brought many environmental and economic benefits to sites in the United States, including improved water quality, enhanced wildlife habitat, and increased tourism. In many developing nations, the Ramsar Convention is the only policy tool available for protecting aquatic ecosystems.
The Austrailan Govenrment considers the broad aim of the Convention, which halts the worldwide loss of wetlands and to conserve those that remain through wise use and management an international imperative enriching communities and continents. The Department of the Environment and Heritage, posits that one of greatest benefits of Ramsar comes through international networking and sharing of resources and reasearchers who work toward common goals.
The mission statement of Ramsar is the guiding principle of the treaty. Conservation and wise use of wetlands, by national action and international cooperation as a means to achieving sustainable development throughout the world is the mission of the Convention. “This means ensuring that activities which might affect wetlands will not lead to the loss of biodiversity or diminish the many ecological, hydrological, cultural or social values of wetlands.”
Eco Tourism
Ramsar sites attract visitors, researchers, naturalists and recreational enthusiasts. The Convention views tourism activities as beneficial to the local, and even national, economies of member partiers. Ramsar calls for “…a positive presumption in favor of providing access and appropriate facilities for visitors”.
Ramsar favors design objectives, prescriptions and management projects developed for public access. Knowledge of wetland issues, biological diversity, ecological threats and other issues of wetland conservation are lessons visitors learn. “Public access and tourism are taken in their widest meaning and include anyone who visits the site for any reason other than official purposes. Access and tourism can make a significant contribution towards the costs of managing Ramsar sites.”
The Louisiana Ornithological Society (LOS) sponsors and conducts two bird counts at the Southwest Louisiana National Wildlife Refuge Complex. The fall and spring meetings take place in the last weekends of October and April in Cameron, Louisiana. “Cameron is the ideal location for such events,” said Dr. Jay Huner of the ULL Center for Cultural Studies and Ecotourism.
The 180-mile Creole Nature Trail was the first National Scenic Byway in the Gulf South. Located midway between New Orleans and Houston, this distinctive corridor winds through southwestern Louisiana amid diverse habitats consisting of oak cheniers, coastal prairies, fresh and saltwater marshes, rice fields and gulf beaches.
According to the Louisiana Coastal Area 2050 Report, almost 900,000 fishing licenses are sold annually in Louisiana. Sport fishing expenditures total $13 billion annually and waterfowl hunting spending $430 million. More than 1.4 million people participated in non-consumptive fish and wildlife activities spending more than $220 million in 1991.


Criticism of Ramsar
“Calestous Juma, a Harvard professor and former United Nations Environmental Program (UNEP) official, argues global environmental organization is unnecessary and may get entangled in bureaucracy. Saying that a global environmental agency would be “too cumbersome to work”. Juma notes that centralized, hierarchical UN agencies are widely regarded as inefficient agencies relying upon a network of bureaucracies rather than interested parties. “The strength of the treaties lies in the fact that they give more power and authority to governments and citizens, not to centralized UN agencies, Juma wrote to the Financial Times of London.”
Rather than existing solely as passive “protected” or “preservation” areas, Ramsar sites usually incorporate and advocate utility through management planning often referred to as wise use. Traditional preservationists associate stricter management of human activity in the management of wetland wildlife refuges. In a May 2005 interview, retired 31 year veteran of the USFWS and 23 year employee of the Lacassine National Wildlife Refuge, Mike Stewart says, “…refuges are just that—a refuge for the wildlife—which means minimizing the impact of humans, like that of duck hunters and the associated equipment they bring onto the refuges.”
Beth Kruchek of Georgetown law school believes a legal angle to this notion may be present. She says, “The limited federal definition (U.S.) of a wetland does not comply with Ramsar’s wise use obligation because it fails to protect the integrity of the wetland ecosystem.”
Implementation of the Wise Use Concept
Article 3.1 of the Convention requires contracting parties to formulate and implement wetland planning to promote the conservation of the wetlands included in the List of Wetlands of International Importance. Ramsar guidelines encourage the wise use of wetlands within the respective member’s authority while respecting transboundary consideration for complete conservation management techniques.
The 3rd Meeting of the Conference of the Contracting Parties (COP) in Regina, Canada in 1987, adopted the following definition and associations with the concept of wise use,
“The wise use of wetlands is their sustainable utilization for the benefit of humankind in a way compatible with the maintenance of the natural properties of the ecosystem.”
The COP3 resolution noted that the concept of wise use “seeks both the formulation and implementation of general wetland policies, and wise use of specific wetlands.” COP3 advocated the use of policy tools for governments to use when promoting wise use practice. The Conference listed five mechanisms necessary to implement wise use in practice,
1) Periodical review of existing legislation to ensure that it is generally compatible with the wise use obligation, and make adjustments if necessary; this applies to particular legislation regarding mandatory wetland destruction or to that which encourages such destruction through tax benefits and subsidies.
2) General wise use legislation for wetlands should consider the following: inclusion of wetlands in the zones of land-use plans that enjoy the highest degree of protection and the institution of a permit system for activities affecting wetlands. Special rules relating to the contents of an environmental impact assessment and consideration for the cumulative effects of separate projects.
3) Legislation for the conservation and wise use of specific wetland sites (e.g. Ramsar sites, ecologically sensitive areas, areas with a high degree of biodiversity, sites containing endemic species, wetland nature reserves).
4) Review of division of jurisdiction among government agencies. Particular attention should be paid to the need to manage coastal wetlands as single units, irrespective of the usual division of jurisdiction between land and sea.
5) Development of cooperative arrangements for water systems shared between two or more countries to achieve wise use.
Ramsar's Work Plan for 2000-2002 includes the specific objective of “developing the capacity of institutions in Contracting Parties, particularly in developing countries, to achieve conservation and wise use of wetlands”.
Ramsar supporters claim the Convention is about finding ways to use wetlands sustainably. Article 2.4 of the Convention established that “The inclusion of a wetland in the List does not prejudice the exclusive sovereign rights of the Contracting Party in whose territory the wetland is situated.” The Convention is not anti-development, nor anti-preservation, but more about planning, management and enjoyment of diverse wetland ecosystems. The treaty does require the overall condition of the wetland remain the central focus of any management plan.
Criteria for Qualification
Selection for the Ramsar List is based on the wetland’s significance in terms of ecological diversity. Article 2(1) provides that each member party is to designate suitable wetlands within its territory for inclusion in the List of Wetlands of International Importance, while article 2(2) establishes the broad criteria to for application. The contracting parties adopted specific criteria and supplement those with application guidelines for identifying sites that qualify for inclusion in the List of Wetlands of International Importance.
Article 2(1) states, “Wetlands should be selected for the List on account of their international significance in terms of ecology, botany, zoology, limnology or hydrology. In the first instance wetlands of international importance to waterfowl at any season should be included.”
U.S. Listing Procedures
The April 6, 1990 Federal Register, Vol. 55, established the U.S. Fish and Wildlife Service’s policy, guidelines and procedures for nominating sites to the List of Wetlands of International Importance. The notice provided supplemental guidance to the Convention for determining site eligibility. The authority for establishment of these guidelines flows from the United States Senate ratification of the Convention on Wetlands of International Importance Especially as Waterfowl Habitat.
The National Wetlands Priority Conservation Plan ensures compliance with the articles of Ramsar. The USFWS reviews sites eligible for inclusion to the list.
The USFWS considers only sites complying with the following,
“The ownership rights are free from encumbrances or dispute and the lands are in public or private management that is conductive to the conservation of wetland:
Maintenance of the ecological and hydrological characteristics of the site(s) should be reasonable assured such that future actions would not result in delisting by the Conference of Parties; and
Proposed sites will only be considered if there is concurrence from State, Commonwealth or territory where the site is located and a Congressional Representative.”
The Service publishes an annual Action Notice in the Federal Register soliciting appropriate nominations to the List of Wetlands of International Importance. This notice specifies the period for submissions and location for material submissions. The USFWS requires submission from the administrative authority or the party holding the title to the nominated land. Local, state and federal support of the nomination is beneficial but required. Congressional submission of the nomination by an elected official is mandatory for any submission to garner acceptance from the USFWS.
Supporting information for site nominations include the following,
1. Nominating authority, including name, address and other information on the administrative authority,
2. Geographical location including details such as latitude and longitude coordinates, and nearby features, settlements, and other identifying characteristics, detailed maps of both the site as well as the surrounding areas,
3. Site description section comprising both a physical and a biological description. The physical description includes details of geomorphology, hydrology and climate and the biological description includes a brief review of habitat types, with lists of both typical and noteworthy fauna and flora.
4. Criteria for inclusion specifying the criterion as listed by the Convention of Parties, which qualifies the site as a Wetland of International Importance.
5. Area, identifying the total area (in hectares) of the proposed site including information on terrestrial and aquatic components.
6. Management policy, noting management practices and traditional activities.
7. Changes in ecological character, giving a brief synopsis of the natural history of the area and land use change impacts to the ecological functions or character of the area.
8. Degree of protection, noting any state, local, national or international recognition or designation afforded to the site, indicating controlled or prohibited activities.
9. Scientific research and facilities, highlighting research underway or facilities provided (if any) for research interests.
10. Reference material, noting key publications, reports, or documents used to compile the information presented.
The USFWS administers review procedures for nominated sites with the assistance of state, federal and non-governmental organizations (NGO’S). Generally, the USFWS openly accepts nominations for inclusion upon the list of Ramsar sites and solicits sites under the previously mentioned federal register notice. The United States Fish and Wildlife Service director presents nominations that meet USFWS criteria of the Convention to the Ramsar Bureau.
Ramsar Guidelines for Implementing the Nominating Criteria
Member countries meet in a Conference of the Contracting Parties or Conference of Parties (COP), where guidelines for the defining criteria are considered and updated to aid parties assessing the suitability of any potential nominee. The process of adopting specific criteria for the identification of Wetlands of International Importance began in 1974. In 1980, the first official Convention criteria emerged at the first meeting of the Conference of the Parties.
The original text of the Convention (Article 2.2) states that:
“Wetlands should be selected for the List on account of their international significance in terms of ecology, botany, zoology, limnology or hydrology, in the first instance, wetlands of international importance to waterfowl at any season should be included”.
In 1987 and 1990, the Conference of the Parties revised the Criteria further, and in 1996, COP6 added new Criteria based on fish and fisheries. In 2002, the Conference of Parties (COP8) addressed an ongoing discussion of socio-economic and cultural importance of wetlands to communities as a potential criteria delimiter. COP8 added to the guidelines for management and planning of Ramsar sites consideration for the social importance of wetlands to the people of the region.
Guidelines for Criteria 1 were updated to read,
“A wetland could be considered of international importance under Criterion 1 if, because of its outstanding role in natural, biological, ecological or hydrological systems, it is of substantial value in supporting human communities dependent on the wetland. In this context, such support would include,
• provision of food, fiber or fuel; or
• maintenance of cultural values; or
• support of food chains, water quality, flood control or climatic stability. The support, in all its aspects, should remain within the framework of sustainable use and habitat conservation, and should not change the ecological character of the wetland”
The Ramsar Convention on Wetlands promotes the conducting of wetland inventories as a tool for identifying the functions and values of wetlands, including ecological, social and cultural values. Wetland inventories serve as a baseline for measuring change in wetlands, for identifying functions and services, for locating wetlands and for identifying priority sites for conservation. Wetland inventory planning and management enables comparisons among wetlands management techniques at different levels of government. In 2001, at the Wetlands International 3rd Board of Members Meeting, in Wageningen, Netherlands, members declared, “…wetland inventory is not an end in itself, but rather an essential step in the decision-making process affecting land use, the conservation of natural resources and water allocation.”
Ramsar Coastal Zone Wetland Management
The need for including the coastal zone management in Ramsar’s guidelines for those states engaged in the national physical planning process was adopted by the Policy Conference on Integrated Coastal Zone Management at the Brisbane Australia 6th meeting of the Contracting Parties in 1996. The COP6 agreed that an estimated 60% of the world’s population concentrates along the coastal strip that extends from shoreline to less than 60 km., or 37.2 miles inland. Recognizing this, COP6 adopted coastal zone guidelines for developing and established countries. The summary report said, “development…poses immense pressure on coastal wetlands in terms of depletion of living resources, pollution loads, reclamation, land fill, and other uncoordinated development, all of which impact on biological diversity.”
Coastal areas are popular landscapes and becoming more so every day. Increased population, coastal residence development, ecotourism growth and other such demands put upon the coast, jeopardized wetland resources and natural ecosystems. Coastal areas of the United States host more than 139 million people, about 53% of the national total population while only comprising 17% of the nation’s land area.
Coastal areas of the U.S. are the most developed in the nation. Coastal population is increasing by 3,600 people per day, with projected totals rising above 28 million people between now and 2015. This rate of growth is faster than that for the nation as a whole.
Currently, over half of the human population in North America lives in coastal cities. In 1960, there were 80 million coastal residents, out of a total 180,671,158 people. Today, the coastal population density is approximately 340 people per square mile, more than four times the U.S. average for population density and by the year 2025, three out of every four Americans will live within an hour's drive of the shoreline.
Louisiana has 7,721 miles of shoreline, bays, tidal lakes, estuaries, sounds, lagoons, and brackish bayous with a coastal population of 2,044,880 residents and growing. In 1993, it was estimated that 60-75% of Louisiana's residents live within 50 miles of the coast.
Coastal zone population predictions of pressure resulted in the U.S. program to address coastal management issues. The Coastal Zone Management Act of 1972 authorized the Coastal Zone Management Program (CZMP) and the National Coastal Management Program, a federal-state partnership dedicated to management and protection of the nation’s coastal resources. The Coastal Programs Division (CPD) within the National Oceanic and Atmospheric Administration’s Office of Ocean and Coastal Resource Management (OCRM) administers the program at the federal level.
Thirty-four states and territories have federally approved coastal management programs overseeing 95,376 national shoreline miles (99.9%). State and federal coastal zone management operate under three guidelines; “sustain coastal communities, sustain coastal ecosystems, and improve government efficiency”.
The 1978 Louisiana State and Local Coastal Resources Management Act, (LA RS 49:214.21), authorized the Louisiana Department of Natural Resource’s Coastal Program (LCRP). The Act also authorized the development of Local Coastal Programs (LCPS) for implementation at the parish level. Once an LCP has received federal and state approval, that LCP establishes coastal use permitting authority in the local parish. Ten coastal parishes, Calcasieu, Cameron, Lafourche, Jefferson, Orleans, Plaquemines, St. Bernard, St. James, St. Tammany and Terrebonne manage local coastal programs with St. Charles and St. John’s plan under development.
The Coastal Resources Management Act, amended (Act 361, LA RS 49:214.21 et seq), protects, develops, and, where feasible, restores or enhances the resources of the state’s coastal zone. According to the Louisiana Department of Natural Resources’ web site, “The law’s broad intent is to encourage multiple uses of resources and adequate economic growth while minimizing adverse effects of one resource use upon another without imposing undue restrictions on any user. Besides striving to balance conservation and resources, the guidelines and policies of the LCRP also help to resolve user conflicts, encourage coastal zone recreational values, and determine the future course of coastal development and conservation.”
A Coastal Use Permit (CUP) Program is a part of the Louisiana Coastal Resources Program. The state Coastal Management Division uses this coastal use, permitting program (CUP) for projects associated with the coastal territory. The CUP is a mechanism for granting permits dealing with the management, development and use projects affecting wetlands located within the state’s coastal zone.
As part of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund) of 1980/1986 and the Oil Pollution Act (OPA) of 1990, polluters are responsible for cleanup and restoration of affected resources in wetland areas.

Methodology
Recommending to Ramsar Wetlands of International Importance Candidates
RIS Procedure
The Ramsar Convention utilizes a reporting obligation tool as an assessment of adequacy for sites nominated to the List of Wetlands of International Importance. The RIS follows Ramsar’s stipulated procedures outlined in the formal document published by Ramsar, Explanatory Notes and Guidelines for Completing the Information Sheet on Ramsar Wetlands.
Recommendation 4.7 of the Conference of the Parties established that a data sheet (RIS) developed for the description of Ramsar sites is used by Contracting Parties wishing to nominate sites for inclusion to the Ramsar list. A Ramsar Information Sheet (RIS) and site map complete the nomination regulations for the List of Wetlands of International Importance. Once completed, the RIS and accompanying maps of the nominated site or site cluster is submitted to the Ramsar Bureau in Gland, Switzerland.
The total length of a completed RIS is not expected to exceed 12 pages. Ramsar requests copies of the RIS in Microsoft Word Format and inclusion of digital maps outlining candidate sites. Additional information on each site, such as taxonomic lists of species and representative status, management plans of the nominated site, regional management plans, copies of important published papers and other materials are to be attached to the RIS nomination. Photographs, prints, transparencies and/or electronic image submissions of the wetland may also be included in the nominating package.
The Ramsar Information Sheet has expanded over the years and the order in which the items appear has changed more than once, resulting in many different formats. The Ramsar Convention Bureau maintains current forms at http://www.ramsar.org. Additional, conservation guidelines published in the African-Eurasian Migratory Waterbird Agreement (AEWA) say that one may save time and effort in the preparation of a preliminary site inventory by limiting the types of information to be gathered to the following,
1. Date the sheet was completed/updated
2. Country
3. Name of wetland
4. Geographical co-ordinates
5. Altitude
6. Area (in hectares)
7. Overview (brief description)
10. Availability of map
11. Name and address of compiler
13. General location (nearest town and administrative region)
18. Fauna
19. Social and cultural values
20. Land tenure/ownership of the site and surrounding area
21. Current land use at the site and in surrounding areas
22. Threats at the site and in surrounding areas
23. Conservation measures taken
28. Jurisdiction
29. Management authority
30. Bibliography (scientific/technical)
The AEWA, further states, sites with documented research and/or extensive data covered in other inventories will suffice for nomination submission. Listing of the name of the site, a reference to the source containing full information on the site, and the key values of the site suffices for nomination purposes.
Nomination of the Southwest Louisiana NWR Complex for listing to Ramsar
Cameron Prairie, Lacassine and Sabine Refuges
The Southwest Louisiana National Wildlife Refuge Complex was established in March of 2000. The Complex comprises Cameron Prairie National Wildlife Refuge, Lacassine National Wildlife Refuge and Sabine National Wildlife Refuge, all of south Louisiana in the United States. The Refuge Complex and federally employed staff of the USFWS, manage, protect and restore over 360,000 acres (145687.43 hectares ) of wetlands habitat in the Complex. Cameron Prairie National Wildlife Refuge, located in Cameron Parish, Louisiana, encompasses 9,621 acres (3893.50 hectares) of marsh and prairie. Nesting, migrating, and wintering waterfowl use the refuge as a critical habitat. Lacassine National Wildlife Refuge, located in Cameron Parish encompasses 34,886 acres (14117.92 hectare) and was established to preserve habitat for migrating and wintering waterfowl. Lacassine NWR also manages a 3,345-acre (1353.70 hectare) wilderness area, a 20,000 acre (8093.75) private lands refuge program for migrating waterfowl in six state refuges, and oversees wetland easements in Jefferson Davis Parish. Sabine National Wildlife Refuge, also located in Cameron Parish is 125,000 acres (50585.93 hectare) of diverse habitat and fresh, intermediate, and brackish wetlands.
The Lacassine National Wildlife Refuge (NWR) maintains a 16,000-acre (6475 hectares) controlled impoundment built to enhance waterfowl resting and nesting habitat. The Lacassine Pool is a primary tool in the management of waterfowl using the area refuges. Fifteen management objectives of the refuge and the pool provide for migratory waterfowl loafing and resting areas, while adjacent areas are managed to support feeding. Submerged aquatics within the pool provide food sources for hundreds of species of waterbirds and waterfowl.
The Complex of refuges provides a wide variety of habitat for wildlife, while accommodating public uses such as hunting, fishing, wildlife photography, environmental education, wildlife observation and analysis. Cameron Prairie and Sabine refuges are on the Creole Nature Trail, a National Scenic Byway and All American Road, cultural programs recognizing the historical and natural significance of traditional roads with the American highway network. Cameron Parish in the state of Louisiana hosts all three refuges, with portions of the NWRs extending into Evangeline and Calcasieu Parishes.
Clustering of WMA’s into a single administrative complex is longstanding practice employed by the USFWS. According to Nita Fuller, Midwest regional chief of the National Wildlife Refuge System, “The decision to consolidate is based on the common resource goals and issues facing all of these river refuges.” said Fuller. She continued, “These refuges also share many of the same contacts with the states, other federal agencies, and a host of non-government conservation groups who partner with us to conserve resources on these important rivers. The consolidation will provide a better coordinated and consistent management throughout the Upper Mississippi River System.”
However, criticism of the complex structure does exist. According to Mike Stewart, former manager of the Lacassine NWR, “…the Complex structure is a matter of administrative benefit only. In my opinion, personnel on the ground are required to manage expansive areas of wetlands.”
Current employees of the Southwest Louisiana NWR Complex support the clustering concept. “Combining the goals of the individual refuges with unified management plans provides continuity in our primary mission to manage the refuges for the benefit of all waterfowl. We do staff the refuges with onsite personnel who report to the complex manager and staff. We have a close relationship with state personnel and all work for the benefit of the entire wetland region.” Complex Planner, Judy McClendon noted, that the three area National Wildlife Refuges host many of the same waterfowl, fish, shrimp and migratory bird populations and share the same watershed-Cameron Creole.
Rockefeller State Wildlife Refuge encompasses 84,000 acres (33993.73 hectares) nestled between the Lacassine and Cameron Prairie NWRs. The state refuge offers waterfowl, wildlife, fish, and birds a continuous or at least near contiguous stretch of protected managed wetlands. Large live oak trees find high ground at Rockefeller, while wading bird rookeries are located behind the refuge headquarters.
The Holleyman-Sheely-Henshaw Migratory Bird Sanctuary is a Baton Rouge Audubon Society sanctuary located on a chenier, coastal ridge, adjacent to the beach in Cameron Parish. In addition to the live oak-hackberry woods of the chenier, the nearby beaches and marshes makes this location an especially diverse area with a high concentration of wildlife.
Regional Geography of Cameron, Calcasieu, Sabine
The Calcasieu-Sabine Basin was historically interconnected with the Mermentau Basin. Dredging of navigation corridors and agricultural draining of wetlands has made the two basins more hydrologically distinct. In the 1920s, industry established a presence in the watershed with the discovery of petroleum in nearby Jennings, Louisiana. Navigational routes made easy access to barges and water transportation that enabled the establishment of many different petroleum based companies in the area. Refining and chemical operations headed by 30 major industries are located within Calcasieu, Sabine and Cameron Parishes, including corporations such as PPG, Conoco, Citgo, Equistar, and Firestone.
In 2002, the USFWS and the Southwest Louisiana NWR Complex notified the public of their intent to seek input for preparation of Comprehensive Management Program. An approved comprehensive conservation plan guides management decisions and identifies refuge goals, long-range objectives, and strategies for achieving refuge purposes. The planning process will consider many elements including wildlife and habitat management, public recreational activities, and cultural resource protection.
Through public notice and subsequent public meetings, management staff began formulation of a program true to the original mission of the Lacassine National Wildlife Refuge. In a May 2005 Lake Charles American-Press, newspaper article, the manager of the Southwest Louisiana Refuge Complex Don Voros said, “We want to go back to the original purpose for which the refuge was established. That impoundment was built to manage waterfowl.” The official mission statement of the refuge reads,
“To protect, restore, enhance, and manage a representative portion of freshwater wetland and associated habitats for the benefit of wintering waterfowl, other migratory birds, threatened and endangered species, and people.”
NWR management staff is charged with upholding the regulatory policy of the USFWS, whereby these refuges were established and set aside in the early 1900’s as resting areas for wintering migratory waterfowl. Taking into consideration the pleas from recreational anglers “where the suggestions and concerns brought forward by the public were focused on what would be done to improve fishing in these refuges” , was a major concern for Complex staff. According, NWR Complex staff announced plans to complete and release a Comprehensive Management Plan for the sites that would reflect the interest of all- humans, flora and fauna-in the summer of 2005.
The Gibbstown Unit and East Cove Unit of Lacassine NWR exist as two management units based upon habitat types. The Gibbstown Unit habitat consists of fresh marsh, coastal prairie and old rice fields. The Gibbstown unit provides excellent habitat for waterfowl, water birds, white-tailed deer, small game, furbearers, and many other wildlife species. Gibbstown unit is managed to provide natural foods for wintering waterfowl and other water birds.
The East Cove Unit consists of intermediate, brackish and salt marshes. It is an integral part of the Cameron Creole Watershed Project, a large marsh restoration project. East Cove is an important habitat for many estuarine marine organisms (shrimp, crab, menhaden, redfish, etc.) and also waterfowl and other water birds. Public use on East Cove includes recreational fishing, boating and wildlife observation. East Cove is accessible only by boat via Calcasieu Lake.

Ramsar Criteria Applied to The Southwest NWR Complex
Criterion 1: A wetland should be considered internationally important if it contains a representative, rare, or unique example of a natural or near-natural wetland type found within the appropriate bio-geographic region.
The Southwest Louisiana NWR Complex is a Representative Example of a Wetland Ecosystem
Ramsar uses a classification system for categorizing wetlands (see appendix). The Convention groups landscapes into marine, inland and fabricated wetlands. The categorization for the Southwest Louisiana NWR Complex includes:
Table 8 Louisiana Southwest NWR Complex Ramsar Wetland Classification

19) 6. (Water storage areas; reservoirs, barrages, dams and impoundments (generally over 8 ha in area)
20) 9. (Water storage areas; reservoirs, barrages, dams and impoundments (generally over 8 ha in area)
Specifically, there are four types of marsh found in Louisiana, all representing excellent examples of wetland ecosystems. Main categories of salt, intermediate/brackish, and marsh are divided into sub-categories of marsh that exist in within the main typology. Renowned researchers, Mitsch and Gosselink detailed these in 1987.
Salt marsh wetlands exist at the margins of ocean or gulf sounds and estuaries, backs of barrier islands, and flooded deltas near closed inlets with regular saltwater tides. Louisiana contains 40 percent of the saltwater marsh in the contiguous United States.
Spartina alterniflora, smooth cordgrass or oyster grass, is the dominant vegetation at the lower elevations of the salt marsh, typically between mean low tide and mean high tide. The Spartina, which prefers high salinity content, is the desired plant of management officials, as this grass is native to the wetland landscape of south Louisiana’s coastal zone.
Smooth cordgrass shares habitat with the perennial glasswort (Sarcocornia perennis) in low tidal marshes where saltwater inundation is greatest. In these saline areas some components of the southern cordgrass prairie include saltgrass (Distichlis spicata), and marshhay cordgrass (Spartina patens).
The dynamic activity of the salt marsh contributes to the high productivity and biological diversity of this wetland community. Tidal flows and wave action transports organic matter into and out of the marsh, continually flushing and enriching the environment. Less saline or brackish marsh exists within narrow zones at the upper edge of the gulf. These exist as part of the salt marsh, while larger expanses in the heads of bayous and in the interior of large marsh islands exist as separate brackish marsh communities.
Brackish or intermediate marsh exists along the margins of sounds and bays, and estuaries somewhat removed but not distant nor separate from the vital connection with the Gulf of Mexico. Freshwater inflow from channels and rivers dilutes much of the salinity of the water in these marshes. Typically, the range of these wetlands is less than that of salt marshes as is the degree of tidal flow. Brackish marshes have a diminished tidal environment. The wetland plant, Juncus romerianus, black needle grass or black rush is the dominant plant of the brackish marsh ecosystem. In these less saline and more brackish conditions, plants include big cordgrass (Spartina cynosuroides), switchgrass (P. virgatum), and Olney threesquare (Scirpus americanus).
Tidal freshwater marsh exists at the margins of estuaries, or rivers and bayous. These marshes regularly or irregularly flood with freshwater tides. “Historically in Louisiana, this marsh type was extensive, but its range has steadily reduced since the mid-1950s due to numerous factors including subsidence, sea-level rise, salt water intrusion, and altered hydrology as a result of river leveeing and oil and gas access canals”. Species that occur in freshwater or slightly brackish wetland sites include bog rush (Juncus effusus), Jamaica sawgrass (Mariscus jamicensis), maidencane (Panicum hemitomon), panicum (P. repens), common reed (Phragmites australis), arrowhead (Sagittaria spp.), California bulrush (Scirpus californicus), softstem bulrush (S. validus), gulf cordgrass (Spartina spartinae), southern cattail (Typhus domingensis), and great cutgrass (Zizaniopsis miliacea). “A sawgrass meadow is a good indication of regular freshwater flow.” Tidal freshwater marsh is distinguished from adjacent swamp forest and upland forests by the lack of a dominant tree or shrub layer.
Wetland Forests, Evergreen, Deciduous, and Mixed
Flooding frequency characterizes the wetland forests of Louisiana. Areas that experience permanent to semi-permanent flooding exist as deepwater swamps while those affected by seasonal river flooding exist as bottomland hardwood forests. Tree species within the community is a defining characteristic of these environments. In these particular wetland environments, the cypress tree (Taxodium sp.) and water tupelo tree (Nyssaceae Nyssa aquatica) or water gum tree, cover the deeper water swamps of the forested wetlands. These wetland communities typically exist with permanent or near permanent standing water on the ground.
Bottomland hardwood forests exist between aquatic and upland ecosystems but have distinct vegetation and soil characteristics. The vegetation in bottom land hardwood forests is dominated by diverse trees that adapt to the wide range of soil, water, and environmental conditions that exist within a floodplain. Differing species of trees exist in this environment, including, the black willow (Salix nigra), red maple (Acer rubrum), green ash (Fraxinus pennsylvanica), laurel oak (Quercus laurifolia), American elm (Ulmus americana), and sweetgum (Liquidambar styraciflua).
Wetland Shrub/Scrub Evergreen, Deciduous, and Mixed
NOAA’s Department of Restoration and Research notes that “A scrub-shrub wetland typifies a community in transition and exemplifies the dynamic nature of wetlands in general”. The scrub-shrub phase acts as a climax community grading shoreward from newly created wetland such as ponds or lakes. Species composition is dependent on the length of water inundation, with black willow (Salix nigra) and dogwood (Cornus sp.) growing in the temporarily to seasonally wet areas and buttonbush (Cephalanthus occidentalis) in semi-permanently flooded areas. The soils in this community typically are wet phases of alluvial soils. They may have been cropland at one time, particularly where they border large constructed reservoirs. They also may be present along the flanks of spoil disposal areas particularly spoil banks along canals dredged through marsh.
Criterion 2: A wetland should be considered internationally important if it supports vulnerable, endangered, or critically endangered species or threatened ecological communities.
The Southwest Louisiana NWR Complex supports endangered and threatened species
The Endangered Species Act (ESA) of 1973 (16 USC 1531, et seq.) is administered by the U.S. Department of the Interior (DOI), U.S. Fish and Wildlife Service (FWS) and the U.S. Department of Commerce (DOC), National Marine Fisheries Service (NMFS). The FWS is primarily responsible for terrestrial and freshwater species and migratory birds and the NMFS for anadromous and marine fish species.
The purpose of the ESA is to conserve “the ecosystems upon which endangered and threatened species depend and to conserve and recover listed species” . Endangered species are species in danger of extinction throughout all or a significant portion of its range. Threatened species are defined as species likely to become endangered in future.
Section 6 of the ESA encourages each state to develop and maintain conservation programs for resident federally listed threatened and endangered species. Management authority arises through provisions granted in section 4 of the Act, which provides for designations of critical habitat for listed species and includes geographic areas “…on which are found those physical or biological features essential to the conservation of the species and which may require special management considerations or protection”.
Almost half of all endangered or threatened species, including birds, wintering waterfowl, and mammals, rely upon coastal waters and associated estuaries for nesting and breeding. Threatened and endangered species using the Southwest Louisiana National Wildlife Refuge Complex include bald eagles, golden eagles, American alligators, sea turtles, terns and even the Louisiana black bear. Louisiana ranks second in the Eastern U.S. for Bald Eagle nesting with more than 100 active Bald Eagle nests found in South Louisiana in and around the coastal zone. The refuges lend excellent habitat for armadillos, swamp rabbits, fox squirrel, nutria, mink, otters, raccoons, coyotes, and white-tailed deer. Numerous fresh and marine fish, frogs, tortoises and turtles, and snake species live on the refuges.
The published list for the State of Louisiana includes 28 animal and 4 plant species. The Louisiana Natural Heritage Program, Louisiana Department of Wildlife and Fisheries (LDWF) maintain species listed as threatened and endangered in Louisiana. “Of the approximately 3,200 plant species that comprise Louisiana's diverse flora, about 2400 are native and about 350 are rare. The Louisiana Natural Heritage Program (LNHP) part of LDWF collects data on rare plant populations. WMA's and refuges currently support 348 rare plant occurrences and 137 natural community occurrences.”

Criterion 3: A wetland should be considered internationally important if it supports populations of plant and/or animal species important for maintaining the biological diversity of a particular biogeographic region.
The Southwest Louisiana NWR Complex supports populations of plant and animal species important for maintaining biological diversity of the Gulf Coast of the United States.
The marshes of the Southwest Louisiana NWR Complex and surrounding region include a range of habitats utilized by both freshwater and saltwater species. More than 95% of all marine species living in the Gulf of Mexico spend all or part of their life cycle in Louisiana’s wetlands.
Researchers record more than 200 bird species at the just at the Cameron Prairie NWR, including waterfowl, songbirds, seabirds, shore birds, upland game birds, raptors and others including white-fronted and Canada geese, green-winged teal, ringnecked ducks, northern bobwhite, mourning doves, hawks, ospreys and eagles.
The hardwood swamps and bottomland forests, as well as the oak cheniers and the coastal prairies of southwest Louisiana provide habitat to land and water birds species migrating and residing throughout North and South America. Louisiana geographically situated in the Mississippi and Central flyways, is often the terminus of these historical travel routes for birds. The coast of Louisiana is a welcome refuge for migratory flights extending from Canada, the Rocky Mountain region, throughout the Midwest of America to the Northern Atlantic Coast to South America and back.
Criterion 4: A wetland should be considered internationally important if it supports plant and/or animal species at a critical stage in their life cycles, or provides refuge during adverse conditions.
The Southwest Louisiana NWR Complex supports fish, mollusk and shrimp at critical stages of their lives and provides refuge for animals and birds migrating to and from the Gulf Coast of the United States and offer protection from hurricanes and tropical storms associated with the coastal zone.
The coastal waters of the Southwest Louisiana NWR Complex comprise numerous species of estuarine-marine shrimp including the brown shrimp (Penaeus aztecus), white shrimp (Penaeus setiferus), seabob shrimp (Xiphopenaeus kroyeri), pink shrimp (Penaeus Ouorarum), and royal red shrimp (Pleoticus robustus). Brown and white shrimp, the most abundant of the shrimp species, spawn in the Gulf of Mexico and use the wetlands as estuaries. Throughout February and March, the brown shrimp larvae move into the lower estuaries of the coastal wetlands, where growth takes place among the nutrient rich wetland waters. Young adult shrimp emigrate into deeper estuarine waters, eventually moving into the Gulf of Mexico, usually within territorial borders of Louisiana, in early to mid summer.
The blue crab (Callinectes sapidus) is the most common and important commercial crab species in the north central Gulf of Mexico. Environmental conditions play an important role in the condition of crab stocks. The blue crab can survive in a range of environments, from offshore marine waters to freshwater marshes. Like the shrimp, the blue crab is dependent upon the state’s estuaries for the completion of its life cycle. In late summer, egg-baring females migrate offshore to spawn. Shortly thereafter, the larvae of the blue crab adopt the inshore migration patterns of estuarine-marine fish. Mature male blue crabs remain in brackish and freshwater estuaries for the remainder of their lives; conversely, female blue crabs complete their life cycle on the continental shelf.
Dr. Jay Huner of the ULL Center for Cultural Studies and Ecotourism, notes, that migrant bird species including perching birds and shorebirds use the area as a vital link in migration patterns. The birds, he says, “…either stage in the area’s wetlands and wooded oak Chenier ridges preparing to fly south across the Gulf of Mexico for the winter or stop in the area to rest and feed upon return from points south during their northward migrations during the spring.” As a result, the refuge complex draws birders and visitors throughout the year where they find loons, grebes, pelicans, cormorants, wading birds, vultures, waterfowl, raptors, shorebirds, gulls, terns, doves, nightjars, woodpeckers, flycatchers, vireos, crows, swallows, wrens, thrushes, warblers, tanagers, sparrows, grosbeaks and buntings, blackbirds and orioles, and finches in the Cameron area during these critical junctures in migration periods.
Criterion 5: A wetland should be considered internationally important if it regularly supports 20,000 or more waterbirds.
The Southwest Louisiana NWR Complex supports more than 20,000 waterbirds.
During the winter months, the Lacassine and Cameron Prairie refuges support peak populations of over 300,000 ducks and geese. “The refuges support one of the largest concentrations of wintering waterfowl of any refuge in the National Wildlife Refuge system.” Historical wintering duck populations and geese at Lacassine are among the largest in the National Wildlife Refuge System.
Snow geese ranging in numbers from 5000 to 10000 migrate, winter and populate Cameron Prairie National Wildlife Refuge during the fall, winter, and spring seasons. Pintail, blue-winged and green-winged teal, mallards, ring-necked ducks, gadwalls, and American widgeon are also common on the refuges during the winter months. In the summer months, populations of black-bellied whistling-ducks, wood ducks, and blue-winged teal breed and live on the refuges.
The refuge preserves a major wintering site for a large population of waterfowl in the United States. The sanctuary provided at Lacassine Pool of the Lacassine NWR, is critical to the long-term health of pintail populations. The Pool, 16,000 acres of controlled water habitat, is one of the key pintail wintering areas in the continent.
Wintering pintail populations have reached almost 400,000 - which is 50% to 80% of the entire southwest Louisiana midwinter survey of ducks. Duck numbers reported in the state’s October 2003 habitat flyover estimate totaled 779,000 of mixed species just in southwest Louisiana, with the state is total of mixed species coming in at 1,270,000. Biologists found an estimated 2.5 million birds along the coastal zone when they flew aerial surveys in January of 2004.
The most diverse and abundant land animal in Louisiana is by far the bird. Louisiana has no less than 411 different bird species that live in the state for part or all of the year. These species descend from 19 orders and 66 families.
The Convention allows this criterion to apply towards wetlands of varying size in different Contracting Parties. Wetlands identified as being of international importance under Criterion 5 are encouraged to include a large enough area to form an ecological unit. This criterion allows for a group of wetlands to be clustered into a complex wetland habitat. This criterion further supports the Louisiana cluster site nomination proposal put forth by this thesis.
Criterion 6: A wetland should be considered internationally important if it regularly supports 1% of the individuals in a population of one species or subspecies of waterbird.
The Southwest Louisiana NWR Complex regularly supports a distinct resident species of waterbird.
The Mottled Duck, a distinct species of duck often confused with the mallard is colloquially referred to as a “Summer Duck” or “Black Mallard or Black Duck” . This species is a permanent resident of the Southwest Louisiana NWR Complex. Black duck (Anas rubripes) populations are decreasing in similar U.S. wetlands due to habitat loss. Black duck habitat is lost as wetlands are eroded and land is developed for human use. Because Black ducks tend to stay away from people more so than other species, the black duck abandons prime wetland habitat in close proximity to human development. The refuges provide a year round habitat for large groups of Mottled Ducks. This duck, is a resident species with estimated numbers averaging over 50,000.

Criterion 8: A wetland should be considered internationally important if it is an important source of food for fishes, spawning ground, nursery and/or migration path on which fish stocks, either within the wetland or elsewhere, depend.
The Southwest Louisiana NWR Complex provides essential sources of food for fishes, spawning ground, nursery and migration paths regional and tropical fish stocks depend upon.
Examples of species include the commercially and recreationally popular red drum or redfish (Sciaenops ocellatus), speckled trout, (Cynoscion nebulosus), southern flounder (Paralichthys lethostigma). Other commercially and recreationally important fish species include sheepshead (Archosargus probatocephalus), Atlantic croaker (Micropogonias undulates), sand seatrout (Cynoscion arenarius), Gulf menhaden (Brevoortia petronus), bay anchovy (Anchoa mitchilli), and catfishes (lctaluridae),
The deeper coastal waters of the Southwest Louisiana NWR Complex act as habitat to many finfish common to the Gulf of Mexico. Species often congregate around the structures of the deepwater drilling rigs. Pilings, stanchions, pipelines and other parts of the rigs act as artificial reefs and provide shelter to offshore species including the commercially and recreationally important red snapper (Lutjanus campechanus) and associated sub species of snapper, the wahoo (Acanthocybium solandri ) or lemonfish, yellowfin tuna (Thunnus albacares ), blue marlin (Makaira nigricans ) and hundreds of species of sharks and even whales.
Louisiana’s oil industry uses offshore rigs and structures that act as artificial reefs and supplement the natural habitat comprised of oyster reefs, mud flats, breakwaters and jetties. These structures provide habitat to encrusting organisms (epibenthic organisms), corals (Phylum Cnidaria), sponges (Phylum Porifera), barnacles, and other crustaceans. These encrusted structures in turn attract bait fish, shrimp, crabs, squid and other reptiles, tortoises, fish and animals, which supply the food chain of the area. Locations farthest offshore support species of tropical and neo-tropical as well as Atlantic and Pacific origin that migrate through the coastal zone waters and wetlands of Louisiana.
Catahoula National Wildlife Refuge
Louisiana has one site on the Ramsar list. Catahoula National Wildlife Refuge (NWR), founded in 1958, is a Louisiana Wetland of International Importance named on June 18, 1991. Catahoula NWR is 25 miles northeast of Alexandria, Louisiana. Catahoula Lake of the NWR is a 26,000-acre (10521.87 hectare) inland wetland that is a historic concentration area for shorebirds, waterbirds and waterfowl. The lake also is a migrating and wintering waterfowl habitat.
Bald Cypress (Taxodium distichum) trees naturally line swamps, bayous, and lowland hardwood forests emerging from the annual flooding of Catahoula Lake located in the Lower Mississippi River Delta ecosystem. White-tailed deer, small game mammals, songbirds, raptors and waterbirds coexist on the refuge with an interesting variety of reptiles and amphibians, including alligators.
Biologists record populations of waterfowl peaking at 75,000 ducks - 100,000 ducks. Waterfowl, primarily mallards, are abundant during the winter period while wood ducks reside year-round. The refuge has an appropriately named artificial water impoundment, Duck Lake, constructed in the 1970s to provide additional management capabilities for waterfowl. Catahoula Refuge also borders a portion of the state’s Dewey Wills Wildlife Management Area and parts of state of Texas’ wildlife refuges, which provide a cohesive clustering of wildlife habitat separated only by the bureaucracy of federal and state administration.
“The Catahoula Lake region and the current Catahoula NWR are among the most important wetland habitats for waterfowl in the world,” said Secretary of the Interior Gale Norton of the Department of the Interior and the Fish & Wildlife Service.
Catahoula Lake is managed through a cooperative agreement among the U.S. Fish and Wildlife Service, the Louisiana Department of Wildlife and Fisheries and the U.S. Army Corps of Engineers. Around July 1 of each year, the lake goes through a draw down of water to encourage the production of the moist-soil vegetation of value to waterfowl. 5,000 acres of the lake is maintained in draw down mode throughout summer and remains at that level until just prior to the opening of duck season, when the lake level is allowed to rise until the majority of the area is covered in about 2 feet of water. Catahoula Lake is raised 4 to 5 feet in the fall, to enhance commercial fishing, where it stays until the following July when the cycle begins again. Hugh Bateman with Ducks Unlimited is manager of the organization's conservation programs, “When water levels are high, Catahoula can cover as much as 20,000 acres, and it has always been a haven for diving ducks, such as canvasback, scaup and ringnecked ducks”.
Louisiana as a Ramsar State
The application of Ramsar Criteria is not limited to the Southwest Louisiana National Wildlife Refuge. The Convention has the potential to extend to other National Wildlife Refuges within the Louisiana Coastal Zone and perhaps inland wetland sites around the state.
Louisiana has an abundance of lakes, rivers, streams and bayous. Those areas under public domain, such as state WMAs and NGO property are eligible for nomination to the Ramsar list, under the U.S. guidelines for nomination of wetland areas.
In 2005, the Louisiana Governor signed a statewide proclamation designating February 2nd as “America’s Wetland Day”. The proclamation called upon citizens “…to learn more about how Louisiana's wetland loss impacts our state, the nation and the world”. The state celebration took place on what is termed “World Wetlands Day”, which commemorates the 34th anniversary of the adoption of the Ramsar Convention. On February 2, 2005, 80 countries observed World Wetlands Day.

Wetlands Definitions
1. Article 1(1) of the Ramsar Convention defines wetlands as, “…areas of marsh, fen, peat land or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed six meters (19.1 feet).”
2. Article 2(1) of Ramsar provides, “The boundaries of each wetland shall be precisely described and also delimited on a map and they may incorporate riparian and coastal zones adjacent to the wetlands, and islands and bodies of marine water deeper than six meters at low tide lying within the wetlands, especially where these have importance as waterfowl habitat.”
3. The Canadian Government’s definition of wetlands is, “Submerged or permeated by water – either permanently or temporarily – and are characterized by plants adapted to saturated soil conditions. Wetlands include fresh and salt water marshes, wooded swamps, bogs, seasonally flooded forest, sloughs – any land area that can keep water long enough to let wetland plants and soils develop.”
4. International Environmental Law Journal definition is, “Encompassing habitats as diverse as mangrove swamps, peat bogs, water meadows, coastal beaches, coastal waters, tidal flats, mountain lakes and tropical river systems”.
5. General Account of the Freshwater Morasses of the United States defines wetlands as, “…all wetlands...in which the natural declivity is insufficient, when the forest cover is removed, to reduce the soil to the measure of dryness necessary for agriculture. Wherever any form of engineering is necessary to secure this desiccation, the area is classified as swamp.”
6. The United States Fish and Wildlife Service declares that, “The term wetlands... refers to lowlands covered with shallow and sometimes temporary or intermittent waters. They are referred to by such names as marshes, swamps, bogs, wet meadows, potholes, sloughs, fens and river overflow lands. Shallow lakes and ponds, usually with emergent vegetation as a conspicuous feature, are included in the definition, but the permanent waters of streams, reservoirs, and portions of lakes too deep for emergent vegetation are not included. Neither are water areas that are so temporary as to have little or no effect on the development of moist-soil vegetation”.
7. The Cowardin definition reads, “Wetlands are lands where saturation with water is the dominant factor determining the nature of soil development and the types of plant and animal communities living in the soil and on its surface.”
8. The U.S. Army Corps of Engineers says, “The term wetlands mean those areas that are inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.”

1991 CATAHOULA LAKE NWR RIS
Criteria: 1, 2, 4, 5, 6. The criteria codes listed here were completed and/or interpreted by the Ramsar Database team, from officially provided information.
Importance: Catahoula Lake is a unique example of a lower Mississippi wetland community. The endangered eagle, Haliaeetus leucocephalus, occurs as a non-breeding visitor. It is the most important inland wetland for waterbirds and shorebirds in Louisiana. Peak counts have exceeded 400,000 in recent years. During the autumn migration, numbers begin to build up from late August, with large numbers of Anatidae present throughout the winter. The highest counts are usually made in the spring as birds return north to breed. Principal wintering species include Anas acuta (up to 200,000) and Aythya valisineria (up to 78,000, or about 25% of the national midwinter count). 19,000 shorebirds were present in September 1989.
Wetland Types: O, M, N, P, Ts, W, Xf, (listed in descending order of dominance)
The site is a large, shallow, poorly drained depression. It is subject to major seasonal fluctuations in water level, both in terms of depth and area extent of inundation. The lake is fed primarily by Little River, as well as numerous smaller watercourses, entering from the north. It is also subject to back-flooding from the Red, Black and Mississippi Rivers. Adjoining the lake are areas of seasonally flooded bottomlands.
Biological/Ecological notes: Few plants are ecologically adapted to the extreme variations in water level, although annual grasses and sedges flourish. The lakebed is characterized by a series of concentric vegetation zones, related to the lake bed contours. The lake's periphery is vegetated by woody species, primarily Planera aquatica and Forestiera acuminata, with irregular occurrences of Taxodium distichum. The next zone is characterized by Cyperus esculentus, with the next zone (decreasing in elevation) dominated Leptochloa filiformis and Eragrostis hypnoides. Dense stands of Echinochloa sp. occur around the frequently flooded parts of the basin, while permanently inundated areas support Sagittaria sp., Heteranthera limosa and Bacopa monnieri.
Hydrological/Physical notes: During the summer, the depth of water is only 30–50 cm, but major spring floods have been almost as deep as 8 m. The basin is drained by French Fork, Old River, and the artificial Catahoula Lake Diversion Canal.
Human Uses: Jurisdiction resides with the Department of Interior, Fish and Wildlife Service. The entire lakebed is owned by the State of Louisiana. Management authority is vested with the Louisiana Department of Wildlife and Fisheries (LDWF) and a full time Wildlife specialist is assigned to the lake. The site is used for environmental studies and wetland conservation. Commercial and sport fishing, and hunting also occur. Limited research facilities are available at the Catahoula National Wildlife Reserve (NWR) and the Saline Wildlife Management Area, both adjacent to the lake. The Catahoula NWR also houses an education centre. Various research projects are presently underway. These include waterbird and shorebird use of the lake, evaluation of the occurrence of lead and steel shot in the soils and duck gizzards from Catahoula Lake, and the impact of deep tillage on the availability of lead shot. The surrounding area is privately owned. Land use is mainly agriculture, animal grazing and logging.
Conservation Measures: The site includes the Catahoula NWR (2,148 ha), situated at the northeastern end of the lake. This area provides a sanctuary for waterbirds in addition to a 410 ha state refuge or rest area near the centre of the lake. A tri-party management plan has been developed between the US Army Corp. of Engineers, the US Fish & Wildlife Service and LDWF. It has been operational since the 1970s and is jointly administered by the LDWF and the U.S. Fish and Wildlife Service through the Catahoula NWR staff. Water level management is regulated under the management agreement. In the past, under natural conditions, the lake flooded in winter and spring, and dried out progressively during the summer. This pattern is now replicated through the manipulation of a series of artificial water control structures. From 1 July onwards, water levels of the lake are considerably reduced. This action exposes the lakebed and ensures development of the plant communities, which grew on the lakebed under natural conditions. In early autumn, the water level is raised to provide for optimum feeding conditions for staging and wintering waterbirds. Lead poisoning in waterbirds has had a major influence on management decisions at Catahoula Lake. Long term, historical hunting at the site has led to the accumulation of a very high density of lead pellets. Research in 1987 showed that the upper 20 cm of the lakebed contained in excess of 250,000 lead pellets per hectare, one of the highest densities known in the USA. Major waterbird lead poisoning incidents have been recorded since the 1950s, but recent research has been conducted to identify and implement optimum management techniques for limiting the availability of lead shot to Anatidae. Such techniques have included water level manipulation and deep tillage of the lakebed. The use of lead shot is also now illegal. Other management efforts have been aimed at reducing encroachment of woody plants onto the open areas of the lakebed, which have the potential to greatly reduce the value of the lake as an area for waterbirds. Both mechanical and environmentally acceptable chemicals have been used to reclaim portions of the lakebed from this invasion. In the Refuge, an information leaflet and species list is available.
Adverse Factors: The presence of lead shot in the lake may continue to effect waterbirds survival. Catahoula Lake overlies an important oil field, which has been commercially exploited for 40 years. Three relatively minor spills have occurred in recent years, but efforts are under way to introduce strict guidelines requiring oil companies to install state-of-the-art pollution control devices and to upgrade their spill contingency plans. Commercial groups continue to unsuccessfully submit development plans for the shoreline area.


Explanatory Note & Guidelines for Completing the Ramsar Information Sheet
Background and context
Recommendation 4.7 of the Conference of Contracting Parties established that the “data sheet developed for the description of Ramsar sites be used by Contracting Parties and the Bureau in presenting information for the Ramsar database, and as appropriate in other contexts”. The Recommendation listed the information categories covered by the “data sheet”, including the “reasons for inclusion” (the Ramsar Criteria) and the Ramsar “Classification system for wetland type”.

Resolution 5.3 reaffirmed that a completed “Ramsar datasheet” and site map should be provided upon designation of a Wetland of International Importance (hereafter referred to as a “Ramsar site”) for the List of Wetlands of International Importance (the Ramsar List). This was subsequently reiterated in Resolutions VI.13, VI.16, and VII.12. This datasheet, formally entitled the Information Sheet on Ramsar Wetlands and abbreviated “RIS”, provides a standardized format for recording information and data about the Ramsar site.

Resolution 5.3 also stressed that information concerning criteria for inclusion (on the Ramsar List), the functions and values (hydrological, biophysical, floral, faunal, social and cultural) of the site, and conservation measures taken or planned were particularly important categories of information; and it emphasized the importance of applying the Ramsar Classification system for wetland type when describing the wetland in the RIS.

Criteria for Identifying Wetlands of International Importance were first adopted in 1974 and refined by subsequent meetings of the Conference of the Parties. The form of the present Criteria was established by Recommendation 4.2 (1990), with additional criteria based upon fish adopted by Resolution VI.2. The Criteria were again substantively revised and, together with detailed guidance for their application, adopted by Resolution VII.11 as part of the Strategic Framework and guidelines for the future development of the List of Wetlands of International Importance. These Criteria and guidelines are included as Annex II of this Explanatory Note.

The Information Sheet on Ramsar Wetlands (RIS) is completed and supplied to the Ramsar Bureau when a Ramsar site is designated by a Contracting Party. In recognition that the status of designated Ramsar sites can and does change, both in terms of their ecological character, the threats to this character, and the conservation management process and actions underway, Resolution VI.13 has urged Contracting Parties to revise the data provided in the RIS at least every six years.

The RISs and their accompanying maps are held by the Ramsar Bureau. The information provided by Contracting Parties in the RIS is used as the basis for entering data and information into the Ramsar Sites Database, managed on behalf of the Convention by Wetlands International under contract from the Ramsar Bureau. The Database is managed so as to provide an information service on Ramsar sites, including undertaking analysis and reporting to meetings of the Conference of the Parties on progress in implementing the Strategic Framework and Vision for the List of Wetlands of International Importance (Resolution VII.11) and other Resolutions of the Conferences of the Parties.

The information provided by Contracting Parties in the RIS, including any supplementary information provided, and held in the Ramsar Sites Database is also used by Wetlands International to compile the Ramsar Sites Directory for each meeting of the Conference of the Parties. This Directory provides a publicly-accessible standardised summary of the features and conservation status of each designated Ramsar site, and is now also available on Wetlands International’s Web site (http://www.wetlands.org).
General guidance
The RIS must be completed in one of the Convention’s three working languages, namely English, French, or Spanish. The RIS and this accompanying Explanatory Note and Guidelines are available in each of the three working languages.

The information provided in the RIS should be clear and succinct, and the total length of a completed RIS should not normally exceed 12 pages.

In the case of a wetland which has been well-studied and well-documented, or which is the subject of special field investigations, far more information may be available than can be accommodated in the RIS. Additional information, such as taxonomic lists of species’ status, management plans, copies of published papers or photocopied reports on the site, should be appended to the RIS and are treated as part of the official record of the site. Photographs (prints, transparencies or electronic images) of the wetland are also especially welcome. It is essential that the source providing any such additional information be noted.

Where the Ramsar site being designated is a very large and complex wetland system, or consists of a suite of separate sub-sites, two levels of approach may be advisable: a broad approach for the system as a whole, and a more detailed approach for each key locality or sub-site within the system. Thus for a particularly large wetland complex it may be appropriate to complete an overall RIS for the whole site and a series of separate RIS datasheets for each key area or sub-site within the complex.

Resolution VI.1 highlights the importance of clearly defining the ecological character of Ramsar sites as the basis for monitoring these wetlands in order to maintain their ecological character. Key features of the ecological character of the site which should be maintained should include those identified as the justification for designation under each Ramsar Criterion applied to the designation. Further guidance on defining and describing ecological character features is provided in the New Guidelines for management planning for Ramsar sites and other wetlands (Resolution VIII.14).

Where a management plan has been prepared for the site being designated, the information provided in the RIS should be consistent with the plan’s description of ecological character features, the values and functions of the wetland, the factors affecting or likely to affect its character, values and functions, and the management planning process, including monitoring.

When a management plan is prepared as part of the management planning process for the site after it has been designated as a Ramsar site, the information in the RIS should be checked and, if necessary, a revised RIS should be completed and sent to the Ramsar Bureau.

The annex to Resolution VI.1 notes that there is a need to increase the value of the information collected for describing and assessing the ecological character of listed sites, and that emphasis should be given to:

• establishing a baseline by describing the functions, products and attributes of the site that give it benefits and values of international importance (necessary because the existing Ramsar Criteria do not cover the full range of wetland benefits and values which should be considered when assessing the possible impact of changes at a site) -sections 12, 14, 16, 17, 18, 19, 20 and 21 of the RIS apply;

• providing information on human-induced factors that have affected or could significantly affect the benefits and values of international importance - section 24 of the RIS applies;

• providing information on monitoring and survey methods in place (or planned) at the site - sections 25 and 26 of the RIS apply; and

• providing information on the natural variability and amplitude of seasonal and/or long-term “natural” changes (e.g., vegetation succession, episodic/catastrophic ecological events such as hurricanes) that have affected or could affect the ecological character of the site - sections 16 and 24 of the RIS apply.


Guidance on information to provide in each numbered section of the Information Sheet on Ramsar Wetlands (RIS)

1. Name and address of the RIS compiler: The full name, institution/agency, and address of the person who compiled the RIS, together with any telephone and fax numbers and e-mail address.

2. Date: The date on which the RIS was completed (or updated). Please use the name of the month, not its numerical equivalent. For example use 6 March [year] or March 6 [year] rather than 6/3/year or 3/6/year so as to avoid confusion arising from commonly used but differing formats for expressing dates.

3. Country: The official (short) version of the Contracting Party/country name.

4. Name of the Ramsar site: The precise name of the designated site in one of the three official languages (English, French or Spanish) of the Convention. Alternative names, including in local language(s), should be given in brackets after the precise name. Ensure that the site name used is the same in this section and on the maps provided. This name will be used precisely as given when the site is added to the Ramsar List.

5. Map of the Ramsar Site: The most up-to-date available and suitable map of the wetland should be appended to the RIS (in hardcopy and, if possible, also in digital format). At least a hardcopy map is required for the inclusion of the site in the List of Wetlands of International Importance. Indicate whether or not a map accompanies the RIS by ticking the appropriate yes or no boxes. The map must clearly show the boundary of the designated Ramsar site. Annex III provides detailed guidance on the provision of suitable Ramsar site maps and other spatial data. A list of the maps supplied and any other relevant maps of the Ramsar site that are available should be included in a note annexed to the RIS.

6. Geographical coordinates: The geographical coordinates of the approximate centre of the site expressed in degrees, minutes and seconds of latitude and longitude (e.g. in the format: 0124’15”S 10416’01”E or 01030’00”N 08451’45”W). If relevant, specify the number of discrete units forming the site. If any disjunct units are situated at least 1.6 km* apart, the coordinates of the approximate centres of each of these units should be given separately (along with individual names or differentiating labels, e.g. “A, B, C”…, etc.). Any discrete units so identified in an RIS should also be clearly labelled on the site map(s). A single site occupying less than 1,000 hectares needs only one central set of coordinates. Location information on larger areas should be supplemented by providing the coordinates of the southwest and northeast corners of the Ramsar site. (See also sections 5. Map and 9. Area).

*This is approximately equivalent to one (1) minute of latitude or longitude (at the equator, in the case of longitude).

If the site is shaped in such a way that the approximate centre point cannot be easily specified, or if such a point falls outside the site or within a very narrow portion of the site, please explain this with a note, and provide the coordinates for the approximate centre point of the largest part of the site.

7. General Location: A description of the general location of the wetland. This should include the name of the large administrative region(s) (i.e., state, province, territory, canton, etc.) within which the site lies (e.g., Alberta, Canada; Punjab, Pakistan; Andalucía, Spain) and the site’s distance (as either a straight line distance or distance by road) and compass bearing from the nearest “provincial”, “district” or other significant administrative centre, town, or city. The human population of the listed centre and its administrative regions (if possible, including at least two levels of administration/ jurisdiction) should also be stated.

8. Elevation: The average and/or minimum and maximum elevation of the wetland in metres above mean sea level. Clearly label each elevation provided, with e.g. “average”, “maximum” or “minimum”).

9. Area: The total area of the designated site, in hectares. If the areas of discrete site units are known, please also list each of these together with the names (or labels) used to identify and differentiate these units (see also section 5. Map).

10. Overview: A brief paragraph about the wetland, providing a ‘word picture’ of the type of wetland and its importance, its main physical and ecological character features, its most important values and functions, and any particularly interesting features. Note also the most significant wetland types, especially if they are the most dominant as identified in 17 b).

11. Ramsar Criteria: Circle or underline the code for each Ramsar Criterion for identifying wetlands of international importance that is being applied to the designation of the site. Refer to Annex II of these guidelines for the Criteria and the detailed guidance provided for their application established by Resolution VII.11.

Note that many sites qualify for designation under more than one Criterion: be thorough and precise in selecting all of the Criteria that apply. The specific reasons justifying the application of each Criterion selected should be provided in section 12. Justification of Criteria selected under section 11.

12. Justification for the application of each Criterion listed in 11. above: For each Criterion selected under section 11. Ramsar criteria above, a specific individual explanation of how that Criterion applies to the site. This section of the RIS is central to the concept of “international importance”. The Criteria codes alone do not convey information on the specific way in which each Criterion applies to a particular site – therefore it is essential to provide sufficient precise description to explain and support each of the Ramsar Criteria codes selected. This text must not just restate the Criterion, but should provide the necessary details to describe the way in which a particular Criterion applies specifically at the site being designated. Refer to Annex II for the detailed guidance for the application of the Criteria (adopted by Resolution VII.11)

A number of points concerning the correct use of specific Criteria and the Guidelines for their application should be particularly taken into account when preparing the justification for the application of the Criteria selected for designation:

i) The guidelines for the application of Criteria 1 and 3 stress that these Criteria should be applied to a wetland in the context of the biogeographic region within which it occurs, but recognises that biogeographic regions can differ between wetland types. The biogeographical region context can also apply to certain reasons for the designation of threatened ecological communities under Criterion 2. The biogeographic region encompassing the Ramsar site and the biogeographic regionalisation scheme applied should be provided in section 13. Biogeography;

ii) Concerning Criterion 5 the guidelines indicate that the actual total number of waterbirds should be stated, and preferably, when available, the average total number from several recent years. It is not sufficient simply to restate the Criterion, i.e., that the site supports >20,000 waterbirds;

iii) For justification of designation under Criterion 6 it is particularly important to recognise that this Criterion must be applied to the regular occurrence of >1% of a biogeographic population of a species or subspecies of waterbird, and to recognise that in most cases the biogeographic range of waterbird populations is larger than the territory of one Contracting Party. For each population listed under Criterion 6 the name of the biogeographic population, as well as the number of birds of this population regularly occurring in the site, should be listed. Recommended 1% thresholds for the application of Criterion 6 are provided by Wetlands International’s publication Waterbird Population Estimates 3rd Edition (2002), which also provides a description of the biogeographic range of each population. Note that this Criterion should be applied only to those waterbird populations for which a 1% threshold is available. However, for populations of waterbird species in taxa not presently covered by Waterbird Population Estimates 3rd Edition, the guidelines indicate that this Criterion may be applied if a reliable population estimate and 1% threshold is available from another source, and that in such cases the information source must be clearly specified. It is not sufficient simply to restate the Criterion, that the site supports >1% of a population, nor is it a correct justification to list populations with numbers in the site >1% of their national population, except when the population is endemic to that country.

iv) For all or some applications of Criteria 2, 3, 4, 5, 6, 7 and 8, the name(s) of the species concerned (scientific name and vernacular name in English, French or Spanish) should be provided in the justification.

v) The Guidelines for the application of Criterion 7 concerning fish and shellfish diversity indicate that a species list alone is not sufficient justification for the use of this Criterion, and that other features of high diversity, including life-history stages, species interactions, and level of endemism are required for the application of this Criterion.

13. Biogeography: The biogeographic region encompassing the Ramsar site and the biogeographic regionalisation scheme applied (with full reference citation) should be provided. Biogeographical specification is essential for the correct application of Criteria 1 and 3 and certain applications of Criterion 2 (see also sections 11. Ramsar Criteria and 12. Justification of Criteria). In this context the guidelines for the application of the Ramsar Criteria (see Annex II) define “bio(geographic) region” as “a scientifically rigorous determination of regions as established using biological and physical parameters such as climate, soil type, vegetation cover, etc.” Note that for non-island Contracting Parties, in many cases biogeographic regions will be transboundary in nature and will require collaboration between countries to establish the locations of representative, rare or unique examples of different wetland types. It is also recognised that the nature of biogeographic regionalization may differ between wetland types according to the nature of the parameters determining natural variation (see Annex II of this Explanatory Note and Guidelines).

There are a variety of different global and supranational/regional biogeographic schemes in use. No single scheme may be universally appropriate or acceptable and Contracting Parties are urged (in the annex to Resolution VII.11) to apply a regionalization scheme which they determine to be the most appropriate and scientifically rigorous approach available.

14. Physical features of the site: A succinct description of the principal physical characteristics of the site covering the following features (where relevant):

• Geology and geomorphology (general features);
• Soil type and chemistry range (Soil family name(s); indication of mineral vs. organic content; typical pH range of soil);
• Sediment characteristics;
• Origins (natural or artificial);
• Hydrology (including seasonal water balance, inflow, infiltration and outflow, salt-water intrusion). Further detail, notably the hydrological values and functions of the site should be included in section 15. Hydrological values;
• Water quality (typical physico-chemical characteristics);
• Depth, fluctuations and permanence of water;
• Tidal range and variations;
• Downstream area (especially in the case of wetlands that are important in flood control);
• Climate – include here only the most significant regular climatic features, e.g., annual rainfall and average temperature range, distinct seasons, typical flooding and drought periods, and any other normal climatic factors affecting the wetland. Recent major or extreme climate events, e.g. flood, drought, hurricane, cyclone or other storm, atypical period of extreme temperatures, etc, that have had an adverse impact on the site should be detailed under section 24. Factors adversely affecting the site’s ecological character).

15. Physical features of the catchment area: A succinct characterisation of the catchment area, covering:

• surface area;
• general geology and geomorphological features;
• general soil types
• general land use
• climate (including characterisation of climate type);

16. Hydrological values: A description of the principal hydrological values of the wetland, for example, the ecosystem services that they provide to people. This may include, but not necessarily be limited to, its role in flood control, groundwater replenishment, shoreline stabilization, sediment & nutrient retention and export, climate change modification, and water purification and maintenance of water quality. Hydrology of the site (as opposed to its hydrological values and functions) should be covered under section 14. Physical features.

17. Wetland Type: In this section first list, by circling or underlining, the full range of wetland types occurring within the site, and then list the wetland types selected in order of their dominance (by area) starting with the wetland type with the largest area. The Ramsar Classification System for Wetland Type (see Annex I of this Explanatory Note and Guidelines) provides the description of what types of wetland are covered by each of the wetland type codes. Note that the wetland types are grouped in three major categories: marine-coastal, inland, and human-made wetlands, and that wetland types under two or more of these categories may be present within a Ramsar site, particularly if it is large.

Since some Marine/Coastal wetland types (e.g. Estuarine waters (type F) or Intertidal Forested Wetlands (type I)) can occur far inland from the coastline, and conversely Inland Wetlands types can occur close to the coastline, please also indicate with additional text in this section the general geographical location of the site relative to the coastline, as either inland or marine/coastal.

When listing the areal dominance of the wetland types, if possible provide the area or percentage of the total area of the designated site composed of each wetland type, although it is recognised that this may be difficult for large sites with a wide variety of wetland types. If the site is composed of more than one discrete unit and different wetland types or different dominance of types occur in different site units, also list the wetland type dominance for each unit (see also the guidance on sections 5. Map, 6. Geographical coordinates, and 9. Area).

If the designated site includes areas of non-wetland habitat, for example where such parts of a catchment are included, it is helpful here to also list the area, or percentage of the total area, of the site formed of these habitats.

18. General ecological features: A description of the main habitats and vegetation types, listing the dominant plant communities and species, and describing any zonation, seasonal variations, and long-term changes. Include a brief note on the native natural plant communities in adjacent areas, as well as the present plant communities (including cultivation) if different from the native vegetation. Information on specific food chains should be included in this section.

19. Noteworthy flora: Additional/supplemental information on plant species or communities for which the wetland is particularly important or significant should be provided here. Do not duplicate information that has already been provided in support of the site’s international importance (in section 12. Justification of Criteria) or in section 18. General ecological features. Specify why each species or community listed is considered noteworthy (e.g., if it is an economically important species).

Endemic plant species, if they have not been considered towards the application of Criterion 3 at the site (e.g., if the number of endemic species was not considered “significant”, following the guidance for that Criterion) can be listed here.

Also list here plant species that have been introduced (accidentally or intentionally) and/or those that are invasive. (Description of the impacts by invasive and/or alien species on the site should be provided in section 24. Factors adversely affecting the site’s ecological character).

General species (occurrence) lists should not be included here or under other RIS sections, but such lists (properly labelled with site details) should be appended to the RIS when they are available.

20. Noteworthy fauna: Additional/supplemental information on animal species or communities for which the wetland is particularly important or significant should be provided here. Do not duplicate information that has already been provided in support of the site’s international importance (in section 12. Justification of Criteria) or in section 18. General ecological features. Specify why each species or community listed is considered noteworthy (e.g., if it is an economically important species, or a “keystone” species, or a species associated with high wetland biodiversity values, e.g., turtles, crocodiles, otters, dolphins).

Endemic animal species that have not been considered towards the application of relevant Criteria at the site (e.g., because either the number of endemic species was not considered “significant” (Criterion 3) or the percentage of endemic fish did not reach the threshold percentage for the application of Criterion 7) should be listed in this section. Noteworthy zoogeographical features (relict populations, unusual range extensions, etc.) should be noted here.

Also list here animal species that have been introduced (accidentally or intentionally) and/or those that are invasive. (Description of the impacts by invasive and/or alien species on the site should be provided in section 24. Factors adversely affecting the site’s ecological character).

General species (occurrence) lists should not be included here or under other RIS sections, but such lists (properly labelled with site details) should be appended to the RIS when they are available.

21. Social and cultural values: An account of the site’s principal social and economic values and functions and “wise use” features presented in Ramsar Handbooks 1 to 6 (e.g., tourism, outdoor recreation, education and scientific research, agricultural production, grazing, water supply, fisheries production) and cultural values and functions (e.g., archaeological sites, historical associations and/or religious significance including its significance to indigenous peoples). For more information see the Guiding principles for taking into account the cultural values of wetlands for the effective management of sites, annexed to Resolution VIII.19. Whenever possible, indicate which of these values are consistent with the maintenance of natural wetland processes and ecological character. Details about values derived from non-sustainable exploitation or which result in detrimental ecological changes should be described in section 24. Factors adversely affecting the site’s ecological character.

22. Land tenure/ownership: Details of ownership/tenure both of the Ramsar site and of the areas surrounding the site. If possible, express different tenure/ownership categories as the percentage of the site to which each applies (e.g., “50% state-owned”). Explain any complex tenure arrangements or formulas. Also explain terms which have a special meaning in the country or region concerned. In the next section (23. Current land use), describe the linkages between the different land tenures described in this section and specific land uses.

23. Current land (including water) use: All of the principal human activities in (a) the Ramsar site itself and (b) in the surroundings and catchment. Give information on the human population in the area, with a description of the principal human activities and main forms of land and water use at the wetland, e.g., water supply for domestic and industrial use, irrigation, agriculture, livestock grazing, forestry, fishing, aquaculture and hunting. Also mention here activities and uses related to research, education and recreation/tourism at the site, but provide the details about each of these in sections 27, 28 and 29, respectively). Some indication of the relative importance, scale and trend of each land and water use should be given whenever possible. Make note if activities or uses are restricted to certain distinct parts of the site (e.g., in only part of a large site or in distinct zones or within particular wetland types). In (b), summarize land and water use in the areas surrounding the site and in its greater catchment that may directly or indirectly affect the status of the designated wetland, and any land uses in downstream areas likely to be affected by the wetland. For further reference on water use, see the Guidelines for the allocation and management of water for maintaining the ecological functions of wetlands adopted by Resolution VIII.1.

24. Factors (past, present or potential) adversely affecting the site’s ecological character, including changes in land (including water) use and development projects: The human and natural factors affecting the ecological character of the site, from both within and around the site (including the greater catchment, if relevant). These may include new or changing activities/uses, major development projects, etc., which have had, are having, or may have a detrimental effect on the natural ecological character of the wetland. For all adverse and change factors reported, supply measurable/quantifiable information (when such data exist), as well as information on the scale, extent and trend of the change factor and its impact: this information should provide a basis for monitoring of ecological character of the site.

It is important to specify both the agent for the change (e.g., diversion of water, drainage, reclamation, pollution, over-grazing, excessive human disturbance, or excessive hunting and fishing, etc.) and the resulting change and its impact (e.g., siltation, erosion, fish mortality, change in vegetation structure, habitat fragmentation, disturbed reproduction of species, physical or ecological change due to climate change, etc.). It is also important to differentiate between factors coming from within the site itself and those factors emanating from outside the site, but which are having or may have an impact on the site. One should also distinguish between potential and existing adverse factors.

When reporting on pollution, special notice should be taken of toxic chemical pollutants and their sources. These should include industrial and agricultural-based chemical effluents and other emissions.

Natural events, including episodic catastrophes (e.g., an earthquake or volcanic eruption) or natural vegetative succession which have had, are having, or are likely to have an impact on the ecological character of the site should be detailed, in order to facilitate monitoring.

Provide information on the history of introductions (accidental or deliberate) of invasive and/or alien species identified in sections 19. Noteworthy flora and 20. Noteworthy fauna and the impacts of any invasions.

25. Conservation measures taken: Details of any nationally relevant protected area status, international conservation designations (in addition to Ramsar site status), and, in the case of transboundary wetlands, bilateral or multilateral conservation measures which pertain to all or part of the site. If a reserve has been established, give the date of establishment and size of the protected area. If only a part of the wetland is included within a protected area, the area of wetland habitat that is protected should be noted. Also describe any other conservation measures taken at the site, such as restrictions on development, management practices beneficial to wildlife, closures of hunting, etc.

Describe here the management planning process, including any management plan, for the site, if this has been developed and is being implemented, including whether it has been officially approved. Cite the management plan document(s) in section 32. Bibliographic references, and whenever possible provide a copy of the management plan as supplementary information to the RIS.

Include information here on any monitoring schemes and survey methods in place at the site. Describe any application at the site of the Ramsar Guidelines for the implementation of the wise use concept (Recommendation 4.10), Additional guidance for the implementation of the wise use concept (Resolution 5.6), or any other instance of the application of other more recently advanced wise use guidelines (“wise use” is a central concept of the Ramsar Convention).

When updating the RIS for an existing Ramsar site, mention if the site is included on, or has been removed from, the Montreux Record and provide details of any Ramsar Advisory Missions that have been undertaken to the site.

Any application of integrated basin-scale/catchment management planning, or integrated coastal/marine zone management planning, involving or affecting the site should be noted. Provide a brief assessment of the effectiveness of protected area legislation or status of any protected areas whenever possible. Involvement of local communities and indigenous people in the participatory management of the site should also be described, in the context of the Ramsar guidelines on this process (Resolution VII.8).

26. Conservation measures proposed but not yet implemented: Details of any conservation measures that have been proposed, or are in preparation, for the site, including any proposals for legislation, protection and management

Summarize the history of any long-standing proposals which have not yet been implemented, and differentiate between those proposals which have already been officially submitted to the appropriate government authorities and those which have not as yet received formal endorsement, e.g., recommendations in published reports and resolutions from specialist meetings. Also mention any management plan which is in preparation but has not yet been completed, approved or implemented.

27. Current scientific research and facilities: Describe here any current scientific research programmes, including monitoring, and projects taking place in the site, and provide information on any special facilities for research that were mentioned in section 23. Current land (including water) use.

Criteria for Identifying Wetlands of International Importance

Adopted by the 7th Meeting of the Conference of the Contracting Parties (1999), superseding earlier Criteria adopted by the 4th and 6th Meetings of the COP (1990 and 1996), to guide implementation of Article 2.1 on designation of Ramsar sites.
Criterion 1: A wetland should be considered internationally important if it contains a representative, rare, or unique example of a natural or near-natural wetland type found within the appropriate biogeographic region.
Criterion 2: A wetland should be considered internationally important if it supports vulnerable, endangered, or critically endangered species or threatened ecological communities.
Criterion 3: A wetland should be considered internationally important if it supports populations of plant and/or animal species important for maintaining the biological diversity of a particular biogeographic region.
Criterion 4: A wetland should be considered internationally important if it supports plant and/or animal species at a critical stage in their life cycles, or provides refuge during adverse conditions.
Criterion 5: A wetland should be considered internationally important if it regularly supports 20,000 or more waterbirds.
Criterion 6: A wetland should be considered internationally important if it regularly supports 1% of the individuals in a population of one species or subspecies of waterbird.
Criterion 7: A wetland should be considered internationally important if it supports a significant proportion of indigenous fish subspecies, species or families, life-history stages, species interactions and/or populations that are representative of wetland benefits and/or values and thereby contributes to global biological diversity.
Criterion 8: A wetland should be considered internationally important if it is an important source of food for fishes, spawning ground, nursery and/or migration path on which fish stocks, either within the wetland or elsewhere, depend.
