The California Oak Mortality Task Force (COMTF) focuses on the plant pathogen Phytophthora ramorum, which can have devastating effects in the wildlands it inhabits and has had substantial impacts on the nursery industry internationally. In 14 coastal California counties and Curry County, Oregon, P. ramorum has caused outbreaks of Sudden Oak Death, killing over a million native oak and tanoak trees. The pathogen also infects the leaves and twigs of common ornamental nursery plants, such as rhododendrons and camellias, which serve as vectors for pathogen dispersal.
