Despite the hardships the Antioch Dunes has faced over the years, this unique habitat still survives today, as do many of its native, endemic, and common plant and wildlife species. U.S. Fish and Wildlife biologists, together with the Friends of the San Pablo Bay National Wildlife Refuge and other volunteers, carefully monitor and manage the refuge’s populations of Antioch Dunes evening primrose, Contra Costa wallflower, and Lange’s metalmark butterfly through weeding and habitat restoration, propagating primrose, wallflower, and buckwheat plantings, rearing and releasing captive-bred Lange’s metalmark butterflies, and organizing butterfly counts during the fall.

These activities take time and manpower – but you can help refuge staff with many of these activities. To volunteer, contact refuge staff at (707) 769-4200 or visit: http://www.fws.gov/refuge/Antioch_Dunes/what_we_do/get_involved.html.
