Audubon Canyon Ranch protects the natural resources of its sanctuaries while fostering an understanding and appreciation of these environments.

Audubon Canyon Ranch properties include the Cypress Grove Research Center on Tomales Bay, the 535-acre Bouverie Preserve in Sonoma and the 1,000-acre Martin Griffin Preserve in Stinson Beach, which is home to one of the San Francisco Bay Area's most significant and most studied Great Egret and Great Blue Heron nesting sites. 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.
