We have written in the past about Cargill’s attempt to mislead the public and government agencies about the ecological value of the Redwood City salt ponds. While Cargill and its development partner, DMB Pacific, have withdrawn their original plan to build as many as 12,000 houses on the site, the companies consistently say they intend to submit another plan to fill the below-sea-level, restorable salt ponds with housing. As Cargill is busy lobbying federal agencies to exempt the ponds from the Clean Water Act and other important environmental regulations that protect the Bay, now seems like a good time to remind ourselves of the beauty and diversity of bird life found on these salt ponds.
The San Francisco Bay salt ponds support hundreds of thousands of migratory shorebirds who rely on the Bay as a key stop on their route along the Pacific Flyway. The San Francisco Bay, in fact, is a recognized site of hemispheric importance for migratory shorebirds, and the Bay’s salt ponds provide important habitat for dozens of species, including several that are threatened or endangered.
Studies from Point Blue Conservation Science (formerly Point Reyes Bird Observatory), a leader in studying shorebirds along the Pacific Flyway, document that the Redwood City salt ponds are home to at least 24,800 shorebirds annually, including the federally threatened Western Snowy Plover, a species whose surviving Pacific coast population now numbers just 1,500-2,000 birds. In addition, Point Blue describes the Redwood City ponds as having “among the highest [bird] counts from the West side of the Bay between the Bay and Dumbarton bridges” making up more than a quarter of the total shorebird population of the region.
The Environmental Protection Agency has called the Redwood City salt ponds a “critically important aquatic resource that warrants special protection,” as has the San Francisco Bay Regional Water Quality Control Board. Even Cargill’s own environmental consultants have observed over 70 different species at the Redwood City salt ponds, and have documented the federally-threatened Western Snowy Plover breeding on site.
Save The Bay has shared photos of the large numbers of birds that live on the Redwood City salt ponds in the past, but to really appreciate the beauty and fascinating behavior of these birds, you have to see them up close and personal.
Cargill has restricted access to the site, so we have turned to Bob Cossins and other talented local photographers for a good look at a few of the species that have been observed on the Redwood City salt ponds. Take a look at the slideshow and learn a little bit more about the shorebirds that are at risk of losing their home if Cargill is successful in their plans to pave over these 1,400 acres of San Francisco Bay. Help us protect the Redwood City salt ponds from development – sign our petition telling Cargill “Don’t Pave My Bay” and spread the word with your friends and neighbors!
