The Pacific Northwest nursery and Christmas tree industries are reaffirming our commitment to provide safe, high-quality products by providing this comprehensive educational Web site about the plant disease caused by Phytophthora ramorum. P. ramorum is a fungus-like organism affecting susceptible trees and woody shrubs. This plant disease has commonly been referred to as Sudden Oak Death.

The Oregon Association of Nurseries (OAN) and the Pacific Northwest Christmas Tree Association (PNWCTA) are hopeful that this Web site will provide you with more information about the evolving science, regulatory prevention and education efforts on this topic.

Please explore this Web site thoroughly. We hope that it answers many of your questions and provides valuable resources for you in understanding this issue. We welcome your feedback at info@oan.org.
