Don Edwards National Wildlife Refuge
Don Edwards San Francisco Bay National Wildlife Refuge covers 19,000 acres around the edges of the South Bay from Redwood City to Fremont. The refuge is named after Congressman Don Edwards, who introduced legislation that established the refuge.
The headquarters and visitor center for the refuge is in Newark, south of Hwy 84. The visitor center building is an impressive multi-story wooden structure built on the side of a rocky hill with panoramic views of marshlands and salt ponds, sloughs, and the Bay to the west. There are exhibits on the wildlife, ecology, and history of the area along with a bookstore, auditorium, restrooms, and an observation deck.
The refuge is home to six endangered species: the California brown pelican, California clapper rail, California least tern, salt marsh harvest mouse, vernal pool tadpole shrimps, and Contra Costa goldfields.
