Sudden Oak Death

sudden_oak_death2_h
UC Cooperative Extension provides general information about sudden oak death (SOD) caused by the pathogen Phytophthora ramorum. We also monitor for symptoms of SOD in Mendocino, Humboldt, and Del Norte counties and frequently near western edge of Trinity County. UCCE-Humboldt/Del Norte, together with their partners, is currently working on slowing the spread of the pathogen in forested settings. The following links and downloads present some of the information we've found most relevant to SOD management and monitoring in the North Coast.
