California Oak Mortality Task Force
http://nature.berkeley.edu/comtf/

The California Oak Mortality Task Force (COMTF) focuses on the plant pathogen Phytophthora ramorum, the cause of Sudden Oak Death. Outbreaks of P. ramorum have killed hundreds of thousands of native oak and tanoak trees in 14 coastal California counties and Curry County, Oregon. The pathogen also infects the leaves and twigs of common ornamental nursery plants, such as rhododendrons and camellias, which serve as vectors for dispersal. The website offers:

• Information about Phytophthora ramorum and the plants susceptible to infection
• Information for nurseries, growers, and other plant care and propagation industries
• Maps of affected land in California
• Photos of diseased plants and of the P. ramorum organism itself
• Regulatory information - County, State, Federal, and International
• Management recommendations for professionals and for homeowners
• A library of publications, research, newsletters, etc
