UC Cooperative Extension provides information about sudden oak death and other disease symptoms caused by the pathogen Phytophthora ramorum. We also monitor for the presence of this pathogen in Mendocino, Humboldt, and Del Norte Counties and are currently working on developing silvicultural techniques for reducing pathogen presence in forested settings. The following links and downloads present some of the information we've found most relevant to sudden oak death management and monitoring in the North Coast. For more information about Phytophthora ramorum in general, as well as information about how it is affecting other California counties, visit the California Oak Mortality Task Force web site at www.suddenoakdeath.org. You can also obtain more information from Yana Valachovic, Humboldt-Del Norte Forest Advisor, or from Dan Stark, Sudden Oak Death Program Coordinator.
