Phytophthora ramorum, a recently discovered plant pathogen, has caused widespread mortality in certain native tree species in 14 counties in coastal California and in 1 southern Oregon county. It also causes a less-severe foliar blight of native under story species, and of numerous ornamental hosts such as Camellias. Much has been learned about the diagnosis, management, and biology of this pathogen since its first detection in the late 1990s.
