BLM OR/WA Curry County Sudden Oak Death Treatment

archived

In 2001, the Oregon Department of Agriculture (ODA) established an emergency quarantine (ORS 603-052-1230) to limit the spread of Sudden Oak Death (SOD). This quarantine prohibits the movement of host material out of the quarantine area, and requires mandatory eradication. . In 2010, the Oregon Department of Agriculture and United States Department of Agriculture - Animal and Plant Health Inspection Service (USDA-APHIS) established quarantines to limit the spread of SOD. In 2015, the quarantine was expanded, and now encompasses 515 square miles of Curry County which is approximately 31% of the county. Sudden Oak Death (SOD) is caused by the pathogen Phytophthora ramorum, and due to aggressive treatments by the BLM and numerous partners is currently limited in Oregon to the United States Department of Agriculture (USDA) quarantine zone in Curry County. SOD is lethal to tanoak, and has also infected evergreen huckleberry, pacific rhododendron, and Douglas-fir. Symptoms vary from plant to plant, and may include leaf spots, needle and tip blight, shoot-tip dieback, and canker formations. Many other plant pathogens cause the same symptoms. The only way to confirm the presence of sudden oak death is through laboratory testing. BLM has funding available to partner with an organization to assist in the continuation treatment of Sudden Oak Death in Curry County. The goal of this project is to control the spread of Sudden Oak Death, and keep it contained within the USDA quarantined area.
