non-profit organization dedicated to protecting Greater
Farallones National Marine Sanctuary's wildlife and habitats through
the development of a diverse community of informed and active ocean
stewards. We collaborate closely with the Sanctuary staff and coordinate

Designated in 1981 because of its rich biological diversity, Greater Farallones National Marine Sanctuary (GFNMS) surrounds the wind-swept peaks of the Farallon
Islands off of the Golden Gate.
The Sanctuary encompasses
3,295 square miles of open ocean and coastal waters
as well as bays and estuaries—from Bodega Head in Sonoma
County all the way down along the San Mateo County coast.
The islands in its midst serve as breeding grounds for more
seabirds than any other area in the contiguous United States.
The Sanctuary contains vital nursery and spawning grounds
for many fish and shellfish. At least 36 species of marine
mammals have been observed within its borders, including 25
endangered species, such as the blue and humpback whales. The sanctuary was expanded from 1,286 to 3,295 square miles in 2015.
