Habitat Restoration and Enhancement
The Terrebonne Basin supports about 155,000 acres of swamp and almost 574,000 acres of marsh, grading from fresh marsh inland to brackish and saline marsh near the bays and the Gulf of Mexico. This project represents a large-scale restoration strategy for the Terrebonne Basin that would rebuild ridge and intertidal marsh habitat that has degraded due, in part, to the Deepwater Horizon oil spill. The project would restore approximately 5,000 acres of marsh and ridge habitat and would be implemented in four increments through multiple design and construction phases. The Bayou Terrebonne Increment is a ridge restoration and marsh creation project located in western Terrebonne Parish. The ridge restoration feature of this project will restore 126 acres of earthen ridge. The marsh creation feature of this project will dredge sediment from offshore to create 1,370 acres of marsh.
