About Us
The nation's first urban national wildlife refuge national wildlife refuge
A national wildlife refuge is typically a contiguous area of land and water managed by the U.S. Fish and Wildlife Service for the conservation and, where appropriate, restoration of fish, wildlife and plant resources and their habitats for the benefit of present and future generations of Americans.
Learn more about national wildlife refuge sits on the southern end of San Francisco Bay. It is indeed a wildlife oasis in an urban sea. The refuge, created in 1972, was largely the result of grassroots efforts by the local community to protect the San Francisco Bay ecosystem. Today, it provides not only critical habitat for threatened and endangered species, but opportunities for people to enjoy the benefits of nature.
What We Do
Don Edwards San Francisco Bay National Wildlife Refuge was established to preserve and enhance wildlife habitat; protect migratory birds and threatened and endangered species; and provide opportunities for wildlife-oriented recreation and nature study for the surrounding communities.
Our Species
Fifteen habitat types exist on the Don Edwards San Francisco Bay National Wildlife Refuge, contributing to the diversity of wildlife on the refuge. More than 340 plant species and 280 species of birds call the refuge home, and millions of individual birds fly through the area during peak migrations. In addition to plants and birds, the refuge provides habitat for fish, mammals, reptiles, amphibians, and invertebrates!
