Field Survey Report

(Revised November 26, 2014)

Abstract. A small survey plot in the White Rock State Marine Conservation Area at Cambria, California, exhibits less diversity than might be expected of the rocky intertidal along the Pacific coast. The middle and lower intertidal zones are dominated by Brillo Pad algae (Endocladia muricata), stunted Turkish towel (Mastocarpus papillatus) and black turban snails (Tegula funebralis), and about half the rock surface in those zones is encrusted with tar spot algae (Petrocelis). Moreover, animals common in the intertidal of immediately surrounding areas are not found at the location surveyed. Continue reading White Rock SMCA Survey Report, March 13, 2014
