Precious Habitat

A tiny remnant of a once-extensive system of sand dunes along the San Joaquin River's southern banks, Antioch Dunes is unique among national wildlife refuges in that it was specifically established to protect three endangered organisms endemic to the area: the Lange's metalmark butterfly, the Antioch Dunes evening primrose, and the Contra Costa wallflower. The refuge's 55 acres provide these and other species precious real estate along an otherwise heavily developed shoreline.

Although the refuge isn't normally open to the public--the dunes are too vulnerable--you can visit on monthly guided tours and other organized events. Any nature lover interested in the Bay Area's native ecosystems should definitely make the effort!
