Located off the 1,100 miles of California coastline, the California Coastal National Monument comprises more than 20,000 small islands, rocks, exposed reefs, and pinnacles between Mexico and Oregon. The scenic qualities and critical habitat of this public resource are protected as part of the National Landscape Conservation System, administered by the Bureau of Land Management, U.S. Department of the Interior. The Monument provides forage, breeding grounds and haul-outs for significant populations of birds and sea mammals.
