Pacific Rocky Intertidal Monitoring: Trends and Synthesis

Study Regions

Intertidal surveys are distributed along the Pacific coast of North America from south-eastern Alaska, USA, to central Baja California Sur, Mexico, spanning two major biogeographical provinces: the Oregonian and Californian. Survey sites have been grouped into 14 study regions, which vary in oceanographic, geologic and other abiotic factors that affect the biology of each site. These large scale factors tend to drive similarities among sites within a given region, but local features such as topography, geology, and wave exposure can also be important drivers of community composition, and can create striking differences in community composition among sites in close proximity to one another.
