Southern Mississippi River Delta, LA

Forty-three acres of salt marsh in the Southern Mississippi River Delta near Venice, Louisiana was restored using thin-layer placement. Dredged material was placed on the marsh to combat sea-level rise, subsidence, and sediment deficiencies. The project successfully reduced vegetation stress and increased elevation. This project was monitored for 15 years, and at the end of the monitoring period the marsh areas that received intermediate sediment depths were stable and resilient to disturbances. Partners on this project included Louisiana State University, the US Environmental Protection Agency, Louisiana Sea Grant College Program, and the US Department of Commerce.
