Sudden Oak Death

Throughout California's coastal counties, tanoaks, coast live oaks and black oaks are dying in large numbers. University of California researchers have isolated a previously unknown fungal species that causes Sudden Oak Death. The fungus is a member of the genus Phytophthora. UC scientists are conducting far-ranging research to determine how the fungus spreads and how it can be stopped.
