This project will continue the construction of oyster barrier reef along the eastern shore of the Biloxi Marsh. The Biloxi Marsh platform is relatively stable geologically as it has a fairly low rate of subsidence. However, erosion on the marsh edge by wave action has resulted in significant loss of this productive habitat. Reestablishment of vertical oyster reefs in conjunction with the reintroduction of small amounts river water via West Maurepas and Central Wetlands diversions will help slow marsh deterioration. In addition to providing protection against waves and storm surge, oyster reefs also provide a broad range of other ecosystem and economic benefits. Once established, these reefs are naturally self-maintaining.
