Atchafalaya Basin. The wetlands of Louisiana are water-saturated coastal and swamp regions of southern Louisiana, often called "Bayou".. The Louisiana coastal zone stretches from the border of Texas to the Mississippi line [1] and comprises two wetland-dominated ecosystems, the Deltaic Plain of the Mississippi River (unit 1, 2, and 3) and the closely linked Chenier Plain (unit 4).

The NWI relies on trained image analysts to identify and classify wetlands and deepwater habitats from aerial imagery. NWI started mapping wetlands at a small scale (1:250,000 map which covers an area the size of 128-1:24,000 USGS topographic maps or approximately 7,400 square miles).
The Wetlands Geodatabase and the Wetlands Mapper, as an Internet discovery portal, provide technological tools that allow the integration of large relational databases with spatial information and map-like displays. The information is made available to an array of federal, state, tribal, and local governments and the public.
In 1965 the San Luis Resource Area of the Bureau of Land Management began a project to restore some of the dry playas in the San Luis Valley to their former condition as wetlands. [6] The Blanca Wildlife Habitat Area covers almost 10,000 acres (4,000 ha) south of San Luis Lakes and near to the Great Sand Dunes National Park and Preserve.
Wildlife Management Areas may be owned or managed by the Louisiana Department of Wildlife and Fisheries. The Enforcement Division ensures compliance of laws and rules and regulations regarding the management, conservation, protection of natural wildlife and fisheries resources, and providing public safety.
The Mississippi River Delta is the 7th largest river delta on Earth and is an important coastal region for the United States, containing more than 2.7 million acres (4,200 sq mi; 11,000 km 2) of coastal wetlands and 37% of the estuarine marsh in the conterminous U.S. [1] The coastal area is the nation's largest drainage basin and drains about ...
A wetland (aerial view) Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species.
Wetlands make up about 5-8% of Earth's terrestrial land surface but contain about 20-30% of the planet's 2500 Gt soil carbon stores. [49] Peatlands contain the highest amounts of soil organic carbon of all wetland types. [50] Wetlands can become sources of carbon, rather than sinks, as the decomposition occurring within the ecosystem emits ...
