The information is made available to an array of federal, state, tribal, and local governments and the public.

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 ...
Wetlands are the home to a large number of bird, amphibian, insect, reptile, grass, and tree species that cannot inhabit any other system, making them at risk to endangerment, as wetlands are being destroyed for urban development and agriculture. [6] Wetlands help combat pollution and climate change, as they filter pollutants and store a large ...
