About This Reserve

This reserve is comprised of two areas—Rush Ranch and China Camp State Park—located 30 miles north and 50 miles northeast of San Francisco, along the salinity gradient of the San Francisco Bay. A primary focus of the reserve is supporting tidal marsh restoration through research, monitoring, and education. The reserve sites serve as valuable reference for the San Francisco region, where nearly 97 percent of the historic tidal wetlands have been lost to development. Reference sites provide a local baseline for scientific restoration activities.

The San Francisco Reserve is one of 30 sites in the National Estuarine Research Reserve System, and is protected for long-term research, water-quality monitoring, education, and coastal stewardship. Daily management is provided by the San Francisco State University with assistance from local partners. NOAA's Office for Coastal Management provides funding, national guidance, and technical assistance.
