Greyhound Rock State Marine Conservation Area (SMCA) is one of two adjoining marine protected areas off the coast of San Mateo County and Santa Cruz County, on California’s central coast. The area is approximately 55 miles (89 km) south of San Francisco. The SMCA is 11.81 square miles (30.6 km2). Within the SMCA fishing and take of all living marine resources is prohibited except the recreational take of giant kelp, squid, salmon, and other finfish, subject to various conditions. Also permitted is the commercial take of giant kelp, salmon, and squid, subject to various conditions.
Greyhound Rock State Marine Conservation Area was established in September 2007 by the California Department of Fish & Game. It was one of 29 marine protected areas adopted during the first phase of the Marine Life Protection Act Initiative. The Marine Life Protection Act Initiative (or MLPAI) is a collaborative public process to create a statewide network of marine protected areas along the California coastline.
Greyhound Rock SMCA is adjacent to Ano Nuevo State Park. Año Nuevo State Marine Conservation Area adjoins the site to the north.
This marine protected area is bounded by the mean high tide line, the offshore boundary of 3 nautical miles (5.6 km) and straight lines connecting the following points in the order listed except where noted:
Point Año Nuevo is used by thousands of breeding seabirds and marine mammals and supports a world-famous elephant seal haul out and breeding ground. The waters surrounding the point attract a concentration of great white sharks and include documented “hotspots” for depleted canary rockfish. Threatened marbled murrelets rest on shore and forage in the lee of the point.
Greyhound Rock SMCA provides habitat for a variety of marine life, and includes rocky intertidal, sandy beach, estuary, offshore rocks and islands, shale reef, bull kelp and giant kelp forest.
The adjacent Ano Nuevo State Reserve and Ano Nuevo State Park have extensive docent programs (including docent lead tours to the elephant seal colony during the months of December through March in Ano Nuevo State Reserve), outreach and interpretive facilities, parking, and an on-site ranger presence to assist with management and enforcement.
