Laguna Point, MacKerricher SMCA, Fort Bragg CA
Field Survey Report

 Abstract. Laguna Point is on the western perimeter of MacKerricher State Park near Fort Bragg CA. MacKerricher is marine reserve designated as an State Marine Conservation Area under the California Marine Life Protection Act (MPA) and provides limited protection for intertidal life. Laguna Point is open coast with a western exposure that is frequented by tourists, abalone divers, and shellfish harvesters. The area was settled by Pomo and other hunter/gatherers thousands of years ago and at Laguna Point their descendents continue the old traditions of harvesting from the sea.

At minus tide, the area just south of Laguna Point’s north margin becomes a small inlet (where on higher tides doghole schooners loaded lumber in the 1880s) below a marine terrace composed of Quaternary sedimentary deposits. Abalone are common in the inlet and the Indians take them by hand from under exposed rocks. Much of the intertidal rock surface is encrusted by marine algae including Endocladia, Neorhodomela, Mastocarpus and Petrocelis. As with other sites in this survey, marine herbivores ̶ limpets, littorines, and chitons ̶ seemed low in proportion to the amount of rockweed, turfweed, and other algae that predominate here. Mussel beds exist outside of the inlet where they are exposed to the open ocean. Continue reading MacKerricher State Park Survey Report, June 14, 2014
