Sudden Oak Death Research and Education Program
Welcome to the WSU Sudden Oak Death program website. Here you will find information about Sudden Oak Death and other diseases caused by Phytophthora ramorum. We aim to provide resources and services for educators, managers, industries and landowners. More information about the services we provide are available at the links below.
Sudden Oak Death is a disease caused by Phytophthora ramorum, a non-native microbe that harms plants (plant pathogen).
Sudden Oak Death has killed hundreds of thousands of oak and tanoak trees in California, and it has affected larch plantations in the UK.
Phytophthora ramorum has only been recovered from Washington, California, Oregon, several European countries, the United Kingdom, and Vietnam. In Washington and Oregon, P. ramorum is found in mainly ornamental plant nurseries.
Phytophthora ramorum has been present in Washington state since 2004, yet no forest outbreaks have occurred as they have in California, Oregon, and the UK. This may not be the case with the next invasive plant pathogen, therefore the use of Best Management Practices (BMPs) for growing clean plants is important for nurseries to adopt.
