Habitat restoration is necessary when natural or human-made degradation of habitat threatens natural ecosystems.
All living creatures are directly tied to the habitats that sustain them. Barataria-Terrebonne contains some of the most diverse and fertile habitats in the world. The 4.2-million-acre wedge-shaped area between the Mississippi and Atchafalaya Rivers contains agricultural lands, forests, swamps, marshes, levees, islands, bays, bayous, ridges, and other habitats. Strictly speaking, the BTES consists of two different estuaries, Barataria and Terrebonne, separated by Bayou Lafourche which runs generally north to south. This estuary is the youngest part of the United States and was built by accumulating Mississippi River sediment over thousands of years.
