Hayward Regional Shoreline

Existing islands at Hayward Regional ShorelineHayward Regional Shoreline is in southern San Francisco Bay, near the east end of the Dumbarton Bridge, and is owned and managed by the East Bay Regional Parks District. The site consists of numerous inactive salt ponds that are now managed for various wildlife species, including California least terns, which are listed as endangered under the U.S. Endangered Species Act. A single pair of Caspian terns nested on islands in the ponds during 1997-2002, but has not nested there since. In 2008, the U.S. Army Corps of Engineers began implementing the plan “Caspian Tern Management to Reduce Predation of Juvenile Salmonids in the Columbia River Estuary,” which seeks to redistribute a portion of the East Sand Island tern colony to alternative colony sites in Oregon and California. Hayward Regional Shoreline is one of three sites in the San Francisco Bay Area where resource managers plan to create or enhance nesting habitat for Caspian terns, as part of this plan. Current plans are to enhance the habitat on one or two small islands in the coming years.
