Audubon Canyon Ranch (ACR)

Audubon Canyon Ranch is a 501(c)(3) not-for-profit environmental conservation and education organization. It was founded in 1962 to safeguard Bolinas Lagoon from irresponsible development, leading the way for the protection of Tomales Bay. 

Today, Audubon Canyon Ranch acts as guardian of four main nature preserves in Marin, Sonoma and Lake counties. These 5,000 acres of tidal flats, marshlands, coastal prairie, oak woodlands and redwood groves provide significant habitat to wildlife and have been placed in our care by generous donors to steward and protect in perpetuity.

ACR's programs and preserves are made possible thanks to the contribution of thousands of hours of volunteer service, and donations from caring individuals, foundations and businesses. Consider becoming a member of ACR today!
