Offshore the small island cluster, “Sea Lion Rocks,” is a portion of the California Coastal National Monument system. The property contains significant natural resources, including important wildlife habitat, several riparian corridors, extensive wetlands, ponds and other water sources, cypress groves, meadows and sand dunes. The Garcia River is prime Coho and Chinook salmon habitat and is a key recovery area in recent Endangered Species Act listings. Migratory waterfowl, shorebirds, raptors, and several special status species may be found on the property. The Black Oyster Catcher feeding here on mollusks in the splash zone is one of the birds of special concern.
