Noxious Weeds:

  • Displace and compete with native and desirable economic plants
  • Impact agricultural and forest economies and resources such as fish, wildlife, recreation, and overall watershed health

The noxious weed policy and classification system includes Oregon’s official noxious weed priority list as designated by the Oregon State Weed Board (OSWB). Oregon Department of Agriculture has compiled profiles of the weeds listed by OSWB. Profiles include information about the weed, images, and locations in Oregon.
