Description: Coast live oak (Quercus agrifolia) is a major species at risk in the current Phytophthora ramorum epidemic in CaliforniaÂ’s oak woodlands. To search effectively for resistant genotypes, it is imperative to have an understanding of the existing host population genetic structure in these forests, and how its reproductive capacity may be affected by major losses. The purpose of our study is to assess and quantify the distribution of genetic variation of coast live oak in central California. To understand the factors that may limit the ability of these populations to recover, we will compare the current mating system in relatively dense coastal populations to open woodland populations in the interior.

Keywords: mating system, pollen flow, Quercus agrifolia, stand structure
