Project Description

In responding to the Deepwater Horizon (DWH) oil spill, the decision to release fresh water from the Davis Pond structure to Lake Cataouatche resulted in the loss of 50 acres of submerged aquatic vegetation (SAV) in the nearshore waters of Barataria Preserve a unit of the Jean Lafitte National Historical Park and Preserve. The PDARP states, “Areas with suitable water quality conditions for SAV growth should be selected and water quality maintained. Additionally, existing SAV should be protected from wave energy and, ideally, restoration should take place where SAV has previously existed.” The preserve meets these conditions except for SAV protection from wave energy. The SAV community in the injured area has not recovered since the original injury occurred, despite the presence of adjacent SAV beds that are reproducing via seeds and vegetative spreading and are not dispersal limited. Contiguous SAV beds reduced erosion on the adjacent marsh shoreline and decreased the resuspension of sediments in the water column by stabilizing the benthic substrate and reducing wave action. The reduced coverage of these SAV beds has likely created a positive feedback loop where reduced cover has further increased sediment suspension and wave energy, thereby increasing erosion to the nearshore and making additional recruitment by new plant material impossible. The objective of this project is to help protect existing SAV from wave energy and create favorable conditions for reestablishment of at least 50 acres of SAV in the park. Additionally, the project would prevent future erosion to the area by reducing wave action to the shorelines. The prin...click on "More Info" link below
