Channel Islands National Park (CINP) includes the five northern islands off the coast of southern California and the surrounding waters out one nautical mile. Approximately 176 miles of coastline surround the islands; 80% of which is composed of rock. The diverse and undisturbed nature of the tidepools of this rocky coastline was recognized as a special feature of the islands in the enabling legislation. To conserve these communities unimpaired for future generations, the NPS has been monitoring the rocky intertidal communities at the islands since 1982. Sites were established between 1982 and 1994 using judgment sampling and considering visitation, accessibility, presence of representative organisms, wildlife disturbance, and safety. This report summarizes the 2007 sampling year efforts (from March 2007 to January 2008) and findings of the CINP Rocky Intertidal Monitoring Program.

“Intertidal ecologists have been struggling with how to adequately monitor the tremendous diversity and heterogeneity of rocky shores for decades. Finally three of the most experienced and established people in the field have done it. Monitoring Rocky Shores will serve as THE central reference guide for scientists intent on understanding the complexities of intertidal ecology.”—John Pearse, coauthor of Animals Without Backbones “The incredibly high taxic, morphological, ecological, as well as biotic diversity of rocky shores makes them ideal sites for ecological studies; however this same diversity also presents innumerable challenges. Monitoring Rocky Shores is long overdue in helping investigators tackle these innumerable challenges. This book provides a broad and important introduction to the habitat, the animals, the methods, and the analyses required constructing informed hypotheses and scenarios for life on rocky shores.”—David R. Lindberg, Museum of Paleontology, co-editor of Phylogeny and Evolution of the Mollusca
