San Francisco Bay NERR

The San Francisco Bay National Estuarine Research Reserve (NERR) encompasses over 3,700 acres of tidal marshes and undeveloped uplands that serve as research sites, outdoor classrooms, and recreation destinations. Reserve staff work to restore tidal marshes and strengthen the coastal community through research, monitoring, training, and education. As a staff we are working to be strong allies and provide stewardship for our local frontline communities around our reserve sites and throughout the Estuary.
