History

edit

It was founded in 1974 as the first urban National Wildlife Refuge established in the United States, and it is dedicated to preserving and enhancing wildlife habitat, protecting migratory birds, protecting threatened and endangered species, and providing opportunities for wildlife-oriented recreation and nature study for the surrounding communities.

As of 2004, the refuge spanned 30,000 acres (120 km2) of open bay, salt pond, salt marsh, mudflat, upland and vernal pool habitats located throughout south San Francisco Bay. About 9,000 acres (36 km2) of salt ponds within the refuge are managed by Cargill Salt, which has perpetual salt-making rights. Cargill uses the salt ponds to concentrate brines as part of its solar salt operation which produces salt for food, agriculture, medical, and industrial uses throughout the Western United States.[3]

Located along the Pacific Flyway, the refuge hosts over 280 species of birds each year. The variety of birds that may call the refuge home or use it as a stopover include white pelicans, white-tailed kites, hawks, ospreys, and eagles. Millions of shorebirds and waterfowl stop to refuel here during the spring and fall migration. It also provides critical habitat to resident species like the endangered California clapper rail and salt marsh harvest mouse. Hundreds of thousands of people visit its diverse wildlife and habitats each year.

The DESFBNWR is one of six wildlife refuges in the San Francisco Bay Area. The others are: Antioch Dunes, Ellicott Slough, Farallon, Marin Islands, and San Pablo Bay. It was renamed in 1995 in recognition of Congressman Don Edwards and his efforts to protect sensitive wetlands in south San Francisco Bay.

With the exception of the red ponds in the foreground, most of the wetlands visible are in the refuge, including the dark green area by the Mowry Slough in the lower left, the area on both sides of the meandering Plummer Creek near the east end of the Dumbarton bridge, and areas on the far side of the bridge on both sides of the bay, up through the brightly reflecting Bair Island area in the top center.
