Noxious Weeds 

What is a noxious weed?

Noxious weeds are plants designated by the state or county as being a menace to public welfare, including agricultural and recreational resources as well as the health of humans and wildlife, and presenting a need for management. The responsibility of weed management is recognized to be shared by private landowners and all levels of government.

Impacts of noxious weeds:

  • Displacement of or competition with valuable crops and native plants

  • Damage to important natural resources within the region such as fish, wildlife, waterways, and recreational areas

From the Jefferson County Noxious Weed List:

Class A weeds are those with the highest priority for eradication (not yet abundant)

Class B weeds are found in abundance and need to be localized

Class C weeds are widespread and in need of control (eradication is unlikely)

Both Oregon state statutes and Jefferson County code emphasize the importance of noxious weed management.

Jefferson County code includes an ordinance providing for the enforcement of weed control efforts by the Jefferson County Board of Commissioners, in the interest of public health, safety, and welfare. By this ordinance, landowners are required to remove noxious weeds from their property and can be fined for refusing to comply with noxious weed removal notices from the Weed Inspector.
