USGS research in the Bay-Delta assesses and informs habitat-restoration activities and contributes to comprehensive ecosystem planning documents for the Bay-Delta, such as the Delta Plan.
More than 90 percent of tidal wetlands found in the Bay-Delta before 1820 have been lost to development or converted to other uses such as agriculture and commercial salt-evaporation ponds. USGS is providing essential science to inform the adaptive management for the restoration of more than 15,000 acres of diked salt ponds in San Francisco Bay.
The USGS has multiple interconnected and interdisciplinary projects associated with the South Bay Salt Pond Restoration Project in South San Francisco Bay. These projects are examining restoration-management actions and their potential for impacts on (1) birds, mammals, and fish and other aquatic species; (2) the sediment supply needed to rebuild tidal marshes; (3) the effects associated with breaching of levees to restore natural tidal flows and marsh processes; (4) the accumulation of sediment-bound contaminants within the restoration; and (5) ground subsidence (sinking of the land surface) due to groundwater pumping. The South Bay Salt Pond Restoration Project can be used as a model of how interdisciplinary science, policy, and management efforts can address complex issues associated with large-scale estuarine restoration and help to provide a mosaic of diverse habitats for wildlife, quality public access, and environmental education.
