The War Against Weeds

Invasive plants in Oregon include knapweed, poison hemlock, and butterfly bush. The author presents a profile of the vegetation management efforts in one area of the state, Clark County. In addition to controlling listed weeds in state- and county- owned areas, Clark County's Weed Management Division is responsible for re-establishment areas (10,900 acres of surface water, parks, and roadsides on the county's 1,325 lane miles). Clark County also has had a public education program in place since 1992 to relate the importance of weed control, including herbicide use, to private property owners. Clark County vegetation management funding includes grants from the Oregon Department of Agriculture. An insert describes Clark County, Oregon's three-tier zone system controlling the spread of weeds along roads.
