Noxious Weed Laws

In recognition of the economic and ecological threats caused by invasive, non-native plants, Washington State has enacted laws to control the introduction and spread of these noxious weeds. The original goal of RCW 17.10 was to limit Washington's economic loss due to noxious weeds in and around agricultural areas. In 1987, this law was revised to incorporate noxious weed control in all natural areas, since the ecological impacts of noxious weeds are so closely tied with Washington's economy.

  • Chapter 17.10 RCW - Noxious Weeds - Control Boards.

    This is the primary noxious weed law, and it holds landowners - including state and county land agencies - responsible for controlling noxious weeds on their property. It also establishes a program for administering the noxious weed law, which is carried out by three groups:

    • Washington State Noxious Weed Control Board

    • Washington Department of Agriculture

    • County and District Noxious Weed Control Boards

  • Chapter 16-750 WAC - State Noxious Weed List and Schedule of Monetary Penalties.

    This WAC contains the Noxious Weed List, which is updated every year, definitions, and descriptions of region boundaries for Class B designate weeds.
