Background: Grassy uplands overlook salt ponds, salt marshes, mudflats, and meandering tidal channels at this south bay refuge. A nature trail winds through the uplands, where northern harriers and peregrine falcons look for prey. The path descends to salt ponds and mudflats teeming with western sandpipers, dunlins, and other shorebirds. Pickle weed and cordgrass line slough channels and ponds favored by willets, black-necked stilts, egrets, and herons, endangered salt marsh harvest mice and California clapper rails hide amoung this vegetation. Thousands of ducks raft up in the open water, including concentrations of northern pintails, northern shovelers, and canvasbacks. Harbor seals may be seen near shore. Watch for terns hunting fish, including the California least tern, an endangered species on the West Coast.

The Habitat: The refuge encompasses grassy uplands (3%), salt ponds (60%), salt marshes (15%), mudflats (20%), and seasonal wetlands (2%).

The Experience: Salt marshes are the most productive ecosystem on earth. Only 15% of the the San Francisco Bay salt marshes remain. It is home to two federally-listed endangered species that live no where else in the world, the California clapper rail and the salt marsh harvest mouse.
