Abstract

Since the discovery of Phytophthora ramorum in southern Oregon forests in 2001, newly infested areas are located each year. We tracked the spread and dispersal using DNA fingerprinting. While among site genetic variance was low, we did find changes in genotype presence and frequency at the site level. These genotypic differences allowed us to map the spread of some individual genotypes demonstrating long and short distance dispersal of P. ramorum in Oregon Forests.
