The article "Stand structure and acorn production in island scrub oaks (Quercus pacifica)" has been accepted to the California Island Symposium Monograph of the Western North American Naturalist. Together with our colleagues from The Nature Conservancy, the island scrub-jay crew has been surveying oak trees across S. Catalina, S. Rosa and of course S. Cruz islands. We found that the three island populations vary tremendously in their stand densities and acorn production, but that the variation does not seem associated with the presence of seed predators and dispersers. We also present the first five years of acorn count data that we collected to figure out if island scrub oaks are classic masting oaks. We will continue counting acorns in the future, in order to understand the effect of varying acorn crops on Santa Cruz wildlife.
