The Conservation Science and Habitat Protection programs of Audubon Canyon Ranch are headquartered at ACR's Cypress Grove Research Center located on Tomales Bay. ACR scientists and volunteers study wintering shorebirds, monitor waterbirds, investigate processes for restoration of coastal marshes, and track heron and egret colonies throughout the northern San Francisco Bay Area.

The Tomales Bay estuary offers extraordinary opportunities for conservation biology, thanks to its simple shape, intermediate size, biological richness and undisturbed quality relative to the nearby San Francisco estuary.
