Audubon Canyon Ranch

Audubon Canyon Ranch

Audubon Canyon Ranch protects 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.

The ACR encompasses two preserves and the Cypress Grove Research Center.

1. Bolinas Lagoon Preserve

This thousand-acre wildlife sanctuary has a rich mosaic of natural communities. Forests of Douglas fir, coast redwood, and California bay blanket the steeper slopes. Open hillsides support grasslands, coastal scrub, and chaparral, redwoods, streams, ponds, and freshwater marsh habitats nestle in the canyon floors. Bolinas Lagoon Preserve supports a major heronry of Great Blue Herons and Great and Snowy Egrets. Audubon Canyon Ranch was founded in 1962 to save the heron and egret nesting colony at this site, which would have been destroyed by development planned for this area. Herons and egrets return each spring to nest in the tops of the tall redwood trees in Picher Canyon. In the shallow waters of Bolinas Lagoon and nearby tidelands, they find ample food for themselves and their young.

The number of nests in this colony varies from year to year but usually totals more than 100 pairs, with Great Egrets making up the majority in recent times. The egrets and herons nesting at Bolinas Lagoon Preserve are a main attraction of this preserve, but you can also find black-tail deer, bobcat, badger, gray fox, raccoon, brush rabbit, meadow mouse, etc. There are also numerous landbirds, reptiles, and amphibians. The Preserve’s frontage along Bolinas Lagoon brings more than 60 species of water and shore birds into view – from sandpipers to osprey to pelicans – as well as some of the resident harbor seals.

2. Bouverie Preserve

This magnificent 500-acre property was donated to Audubon Canyon Ranch by David Bouverie in 1979. Oak woodlands, mixed evergreen forest, riparian, and chaparral are present in this landscape dominated by Stuart Creek Canyon. This location is known for its amazing spring wildflowers. Because of its diversity, Bouverie Preserve is home to a rich and distinct combination of plants and animals, including more than 130 species of birds, 350 species of flowering plants, and numerous large mammals such as the bobcat, grey fox, and coyote.

ADA Accessibility Notes

Access for people with disabilities is provided at Bolinas Lagoon Preserve through the Ranch yard, which takes you to the bird hide, an excellent area for viewing the nesting birds with specially designed picnic tables, the display hall, and the bookstore. Access for people with disabilities is also provided to the teaching ponds where newts and other pond life can be found.

At Bouverie Preserve, an accessible path leads from the parking lot through an oak woodland to a viewing area with benches, which is good for bird watching, is near a seasonal stream, and overlooks a meadow covered with wildflowers in the spring. The path is short, about 300 feet long. There is also access for people with disabilities to the Gilman Hall Education Center.
