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 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 Deltaic Plain contains numerous barrier islands and headlands, such as the Chandeleur Islands, Barataria Basin Barrier Islands, and Terrebonne Basin Barrier Islands. The Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) program, through the NOAA Habitat Conservation National Marine Fisheries Service funded $102 million in construction for deteriorated wetlands and barrier island habitats.
