Areas of land that are wet by surface water or groundwater for long periods of time so that the animals and plants adapt to them for a part of their lifecycle are considered Wetlands. This includes areas that are inundated with fresh or saline water. Lagoons, lakes, rivers, estuaries, swamps, coral reefs and seagrass beds are examples of ...
Example of land loss in coastal Louisiana between 1932 and 2011; detail of Port Fourchon area. Coastal erosion in Louisiana is the process of steady depletion of wetlands along the state's coastline in marshes, swamps, and barrier islands, particularly affecting the alluvial basin surrounding the mouth of the Mississippi River.
Biomass can refer to species biomass, which is the mass of one or more species, or to community biomass, which is the mass of all species in the community. It can include microorganisms, plants or animals. [3] The mass can be expressed as the average mass per unit area, or as the total mass in the community.
Inorganic sediments found within the ecoregion are soft and have high water contents. They will shrink dramatically upon draining. The wetlands and marshes act as a buffer to help moderate flooding and tidal inundation during storm events. Lack of sediment input, delta erosion, land subsidence, and rising sea levels threaten the region.
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).

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.
Permits developments in wetlands that do not cause adverse effects on water quantity, water quality, hydrologic functions, and terrestrial and aquatic habitats in wetlands [44] Policy for Development in Wetlands: Criteria for issuing permits under Section 48 of the Water Resources Act for all development activities in and affecting wetlands [45]
Wetlands can be part of the lentic system, as they form naturally along most lake shores, the width of the wetland and littoral zone being dependent upon the slope of the shoreline and the amount of natural change in water levels, within and among years. Often dead trees accumulate in this zone, either from windfalls on the shore or logs ...
