DescriptionTens of thousands of tanoak (Lithocarpus densiflorus), coast live oak (Quercus agrifolia), California black oak (Quercus kelloggii), Shreve oak (Quercus parvula var. shrevei), and madrone (Arbutus menziesii) have been killed by a newly identified species, Phytophthora ramorum, which causes Sudden Oak Death. Sudden Oak Death was first reported in 1995 in central coastal California. The pathogen also infects rhododendrons (Rhododendron spp.), huckleberry (Vaccinium ovatum), bay laurel (Umbellularia californica), California buckeye (Aesculus californica), and other tree and shrub species, but usually causes only leaf spots and twig dieback on these hosts.
