Abstract

We are studying how P. ramorum survives and spreads in Oregon tanoak forests. The Oregon outbreak is similar to the epidemic in redwood-tanoak forests of California, with several important differences, however. The disease is confined to scattered stands within a 12 m² area, and it is subject to an ongoing eradication effort. While eradication has not yet eliminated the disease, inoculum levels are low. As a consequence, myrtlewood is seldom infected and is not important in the epidemic.
