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).

In drier wetlands of the PPR, the vegetation varies from spikerush, which is found in the wetter areas of the wetland, to foxtail barley and wheatgrass on the outer edges of the wetland. [7] The variable availability of water in the Prairie Pothole Region is buffered by an abundant seed bank under the soil, comprising species that thrive under ...
Major remaining wetlands of the United States. Red dots indicate critical wetlands. The U.S. Fish and Wildlife Service's National Wetlands Inventory (NWI) produces and provides information on the characteristics, extent, and status of U.S. wetlands and deepwater habitats and other wildlife habitats. The NWI also produces periodic reports on the ...
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.
Marjory Stoneman Douglas described the area as a "River of Grass" in 1947, though that metaphor represents only a portion of the system. The area recognized as the Everglades, prior to drainage, was a web of marshes and prairies 4,000 square miles (10,000 km 2) in size. [36] Borders between ecosystems are subtle or imperceptible.
There are a number of environmental issues in Florida.A large portion of Florida is a biologically diverse ecosystem, with large wetlands in the Everglades.Management of environmental issues related to the everglades and the larger coastal waters and wetlands have been important to the history of Florida and the development of multiple parts of the economy of Florida, including the influential ...
For example, wetland plants may produce dense canopies that cover large areas of sediment—or snails or geese may graze the vegetation leaving large mud flats. Aquatic environments have relatively low oxygen levels, forcing adaptation by the organisms found there. For example, many wetland plants must produce aerenchyma to
The ecoregion provides important habitat for fish and wildlife, and includes the largest continuous system of wetlands in North America. It is also a major bird migration corridor used in fall and spring migrations, known as the Mississippi Flyway. Potential natural vegetation is largely southern floodplain forest and is unlike the oak ...
