Northern Mississippi River Delta, Louisiana

Salt marsh near Venice, Louisiana, on a northern portion of the Mississippi River Delta is experiencing high rates of sea-level rise, subsidence, fragmentation, and disturbance from oil and gas exploration. Dredged material was placed on the marsh to restore elevation and provide opportunities for emergent marsh to recolonize fragmented areas. Both emergent marsh and shallow open water areas responded positively to the thin-layer placement project, and new marsh was able to grow successfully. Partners on this project include Johnson Controls World Services, Inc., the US Geological Survey, and the National Wetlands Research Center.
