Audubon Canyon Ranch

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 a system of nature preserves spanning 26 properties in Marin, Sonoma and Lake counties. These 5,000 acres provide significant habitat to wildlife and have been placed in our care by generous donors to steward and protect in perpetuity. ACR works to improve global environmental health by conserving and stewarding valuable natural resources, managing for ecological resiliency, providing scientific solutions to ecosystem management, and teaching generations of conservationists in ways that strengthen natural and human communities. ACR's programs are made possible thanks to the contribution of thousands of hours of volunteer service, and donations from caring individuals, foundations and businesses. ACR is an independent non-profit organization with 501(c)3 status. Our tax ID number is 94-6069140.
