Audubon Society
The Marin Audubon Society was established in 1956 as part of the effort to prevent development of houses on Richardson Bay tidelands. In its early years, Marin Audubon Society (MAS) was one of the founders of Audubon Canyon Ranch. MAS also was instrumental in protecting Bothin Marsh in Mill Valley, and the Marin Islands National Wildlife Refuge in San Rafael, which supports the largest heron rookery in San Francisco Bay.

San Francisco Bay Trail
If you have ever walked across the Golden Gate bridge, flown a kite along the waterfront in Tiburon, in-line skated on the Foster City levee, hiked through the San Francisco Bay National Wildlife Refuge, or windsurfed off Candlestick Point, you too have enjoyed the Bay Trail. The Bay Trail is a planned recreational corridor that, when complete, will encircle San Francisco and San Pablo Bays with a continuous 400-mile network of bicycling and hiking trails. It will connect the shoreline of all nine Bay Area counties, link 47 cities, and cross the major toll bridges in the region. To date, approximately 240 miles of the alignment—over half the Bay Trail’s ultimate length—have been completed.
