San Francisco Bay National Estuarine Research Reserve

San Francisco Bay National Estuarine Research Reserve protects 10,000 acres of tidal marshes, mudflats, and open water where fresh meets salt. This isn’t just scenic waterfront—it’s a living laboratory studying how estuaries filter pollution, buffer storms, and support countless species. While tourists flock to the Golden Gate, this reserve does the quiet work of keeping the Bay ecosystem alive. Rep the wetlands that protect our coasts and prove conservation happens in urban backyards too.
