  • Mission:
  • Audubon Canyon Ranch's mission is to protect the natural resources of its sanctuaries while fostering an understanding and appreciation of these environments. We educate children and adults, promote ecological literacy that is grounded in direct experience, and conduct research and restoration that advances conservation science. ACR's vision is for all adults and children to feel a strong connection with the wonder and beauty of the natural world. We are working to support the development of a community of people who restore and preserve the natural environment. We also strive to help the scientific community and community-at-large have a greater understanding of conservation science and a shared commitment to habitat management.

  • History:
  • Audubon Canyon Ranch was founded in 1962 to save one of the largest heron and egret nesting sites on the west coast. Following the campaign to save Canyon Ranch, those early pioneers of Marin's conservation movement began a grassroots crusade to preserve the open spaces of Marin County. This success changed the area's land-use forever. ACR became the only local non-governmental organization purchasing land and creating sanctuaries. By 1970, ACR was also addressing the threat of development to Tomales Bay by purchasing critical tidelands, In 1979, David Bouverie donated a large land holding, which would become the 500 acre Bouverie Preserve in Sonoma County. ACR now protects 2,000 acres in 27 properties in Marin and Sonoma Counties. These lands serve as wildlife sanctuaries and centers for environmental education and conservation-based research, and every year we learn more about these natural ecosystems and their unique value within the ecological landscape.
