Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is expanding the Phytophthora ramorum quarantine area in Curry County, Oregon. APHIS is taking this action in response to the confirmation of Phytophthora ramorum in additional areas. The Oregon Department of Agriculture has established an intrastate quarantine for the areas in Curry County that mirrors the federal regulatory requirements as specified in 7 CFR 301.92. This Federal Order will expand the current quarantine area in Curry County from 264 square miles to 515 square miles.

Phytophthora ramorum is the pathogen that causes sudden oak death (SOD), ramorum leaf blight, or ramorum dieback. Sudden oak death was first reported in 1995 on tan oak in Mill Valley (Marin County), California. Since that time, APHIS has quarantined portions of Curry County, Oregon and the following counties in California for Phytophthora ramorum: Alameda, Contra Costa, Humboldt, Lake, Marin, Mendocino, Monterey, Napa, San Francisco, San Mateo, Santa Clara, Santa Cruz, Solano, and Sonoma.

Through ongoing surveys, APHIS continues to define the extent of the pathogen's distribution in the United States and uses quarantines and public education to limit its artificial spread beyond infected areas. Details on APHIS-designated P. ramorum quarantined and regulated areas and the conditions to move regulated articles are in 7 CFR 301.92 and at:

Under IPPC Standards, Phytophthora ramorum is considered a pest that is present: only in some areas and subject to official control in the United States.
