Landels-Hill Big Creek Reserve

Black abalone are a proposed Endangered Species. Withering disease has been responsible for major population declines in the Southern part of their range, but predation by sea otters, another endangered species, is also a cause of mortality. I am looking at possible relationships among the quality of available habitat refuge (sufficiently deep crevices), local otter density, and abalone size and abundance. I am interested in whether the abalone are restricted to deep refuges in areas with high otter density, thus limiting their population. Is there more habitat available to abs when there is less threat of predation? Does this affect the population structure?
