Engle JM and Davis GE. 2000. Ecological Condition and Public Use of the Cabrillo National Monument Intertidal Zone, 1990-1995. Open-File Report 00-98. U.S. Geological Survey. Sacramento, California
Results of 6 years of monitoring 11 index species in the rocky intertidal communities in Cabrillo National Monument. Used fixed plots, photoplots, bird censuses and transects. The results indicate significant human impact (from visitors - trampling, frightening birds, collecting, and more general impacts - pollution and litter washed up from the ocean). Species monitored are boa kelp (Egregia menziesii), red algal turf (mostly Corallina spp.), surf grass (Phyllospadix spp.), aggregating anemone (Anthopleura elegantissima), white acorn barnacles (Chthamalus fissus/dalli), pink thatched barnacle (Tetraclita rubescens), goose barnacles (Pollicipes polymerus), owl limpet (Lottia gigantea), black abalone (Haliotis cracherodii), California mussel (Mytilus californianus), ochre sea star (Pisaster ochraceus).
