"The Gulf of Mexico coastal region (Gulf Coast) stretches over the shoreline areas of five U.S. states: Texas, Louisiana, Mississippi, Alabama, and Florida. The coastal environment has been altered over time due to changes in hydrology, loss of barrier islands and coastal wetland habitat, issues associated with low water quality, human development, and natural processes, among other things. The federal government has addressed these changes through ecosystem restoration activities in the region over the past few decades. Major restoration projects led by the U.S. Army Corps of Engineers (Corps), the Fish and Wildlife Service (FWS), the National Oceanic and Atmospheric Administration (NOAA), and the Environmental Protection Agency (EPA) have been implemented. Significant state and local efforts to restore the Gulf Coast have also been undertaken, in some cases in consultation with the federal government."
