Audubon Canyon Ranch owns and acts as guardian of four nature preserves in Marin and Sonoma counties, California. These 5,000 acres are made up of tidal flats, marshlands, coastal prairie, oak woodlands, grassland, chaparral, mixed evergreen forests and redwood groves. They provide significant habitat to wildlife and have been placed in our care by generous donors to steward and protect in perpetuity.
