San Francisco Bay National Estuarine Research Reserve

California’s San Francisco Bay reserve is comprised of more than 3,700 acres over two sites at Rush Ranch and China Camp State Park. The reserve’s expansive tidal marshes and undeveloped uplands serve as research sites for scientists; classrooms for teachers, land managers and naturalists; and inspiring places for Bay Area residents to visit. The reserve is home to abundant wildlife, including the endangered California red-legged frog, river otters, foxes, raccoons, badgers, deer, bobcats, great blue heron, ruddy ducks, red-tailed hawks, northern harriers, and the endangered clapper rail. Reserve staff work with partners to support tidal marsh restoration and community resilience through research, monitoring, training, and education.
