We are one of the four regional Plant Councils established through the National Association of Invasive Plant Councils. Originally formed as the Pacific Northwest Exotic Pest Plant Council (PNW EPPC) in December of 1993, the council was later revived and renamed in 2007 to be the Pacific Northwest Invasive Plant Council (PNW IPC) who we are today. The PNW IPC region includes the states of Oregon, Washington, and Alaska, and the Provinces of British Columbia and Yukon.
