Sudden Oak Death Pathogen is Evolving, Says New Study that Reconstructs the Epidemic

A new UC Berkeley-led study finds that the pathogen responsible for Sudden Oak Death, a disease that has felled millions of oaks and tanoaks along the Pacific Coast, is evolving, suggesting that movement of infected plants between different quarantined regions should be minimized. The study also revealed that the pathogen got its first toehold in California's forests outside a nursery in Santa Cruz and at Mt. Tamalpais in Marin County.
