​In 2012, the South Bay Salt Pond Restoration Project constructed 16 new nesting islands in Pond A16 in Alviso to provide nesting habitat for waterbirds. Forster's Terns, once abundant nesters in Pond A16, have not returned to nest there since the construction of the new islands. The U.S. Geological Survey (USGS), San Francisco Bay Bird Observatory, and U.S. Fish and Wildlife Service, with funding from Valley Water, are using social attraction on six islands to help re-establish Forster's tern breeding colonies at Pond A16.
