In the last century, coastal Louisiana has lost an estimated 4,833 square kilometers (1,866 sq mi) of land, approximately the size of Delaware's land area. [1] Coast wide rates of wetland change have varied from −83.5 square kilometers (−32.2 sq mi) to −28.01 square kilometers (−10.81 sq mi) annually, with peak loss rates occurring ...
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).
Currently the Wetlands Geodatabase contains over 34,500 7.5 minute map areas in a seamless ArcSDE geodatabase format. This represents wetland map data for approximately 64 percent of the conterminous U.S., 30 percent of Alaska, 100 percent of the windward islands of Hawaii, 77 percent of Puerto Rico and the U.S. Virgin Islands and, 100 percent ...
The Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) is a 1990 United States federal law that provides funds for wetland enhancement. [1] The law is implemented by federal and state agencies, focusing on restoration of lost wetlands of the Gulf Coast , as well as protecting the wetlands from future deterioration.
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).

Given the public benefits provided by wetland ecosystem services, such as flood control, nutrient farming, habitat, water filtration, and recreational area, [3] the estimations that over half the acreage of wetlands in the United States has been lost within the last three centuries is of great concern to local, state, and federal agencies as ...
For example, it is closely linked to land change science, the interdisciplinary of land use and land cover change and their effects on surrounding ecology. Another recent development has been the more explicit consideration of spatial concepts and principles applied to the study of lakes, streams, and wetlands in the field of landscape limnology .
