About the Washington State Noxious Weed Control Board

Who We Are

The Washington State Noxious Weed Control Board (the Board) consists of twelve volunteer members:

  • Five are elected by members of County and District Weed Boards from various regions in the state
  • Six are appointed by the Director of the state Department of Agriculture
  • One is appointed by the Washington State Association of Counties
  • Three of the six appointed by the Director of the state Department Agriculture are non-voting scientific advisers who provide expertise in weed identification, control methods, and aquatic invasive weed species


What We Do

The Noxious Weed Control Board advises the Washington State Department of Agriculture (WSDA) about noxious weed control in Washington State.

  • Coordinate Noxious Weed Control

Through its actions and policy decisions, the State Control Board helps coordinate and supports the activities of the 38 county Noxious Weed Control Boards and weed districts of Washington who enforce the control of noxious weeds on private and public lands. The State Board also works with neighboring states and British Columbia, and provides leadership on regional and statewide noxious weed projects. 

  • Update the Noxious Weed List

The Board maintains the state's official list of noxious weeds that landowners may be required to control. This list is established in the Washington Administrative Code, or WAC 16-750. The listing process, the schedule for adding a plant to the Noxious Weed list, is in WAC 16-750-022

  • Educate the Public About Noxious Weeds

The Board also publishes educational materials about noxious weeds that are used by local weed boards and districts and distributed free to the public.

Our Mission

To serve as responsible stewards of Washington by aiding in the protection and preservation of the land, water, and resources from the degrading impacts of noxious weeds.

We believe that the prevention of Noxious Weeds is the best approach and may be achieved through full implementation of the state Noxious Weed law. To further this approach, we strive for increased public awareness through improved educational efforts.

As the Board, we do not deal directly with control activities; rather, we work to achieve control through local county weed boards, weed districts. For that reason, we seek to improve communication, gain cooperation, and enhance coordination of the collective efforts of noxious weed control.

Finally, we believe that Noxious Weed control is best carried out by strong, adequately funded programs at the local level. Thus, we strive to build public support for local programs, and to empower those programs to be more successful.
