Washington State Noxious Weed Control Board.
The Washington State noxious weed list is updated every year, and all Washington residents can submit proposals to add or remove species, change the class of a listed noxious weed, or to change the designated area in which control is required for a Class B noxious weed. Anyone, including citizens, tribes, organizations, government agencies, and county noxious weed control boards may participate in the listing process by submitting a proposal or by submitting testimony about proposed changes to the noxious weed list. In fact, Washington's open, inclusive listing process is lauded by other states for its encouragement of public participation. Learn more about the listing process here.

To determine which pests posed immediate threats, MITPPC undertook an expansive evaluation process. It convened 15 expert panelists, who ultimately identified 124 significant invasive species threatening our state. This panel also identified 17 criteria that could be used to rate species in an objective, computerized ranking system. Criteria included factors like environmental and economic impact, ability to establish and spread and proximity to the state. Rankings are updated regularly, no later than every other year or as new threats emerge on a more urgent basis. The full whitepaper, "Minnesota's Top 124 Terrestrial Invasive Plants and Pests: Priorities for Research (PDF | 1.4 MB)," outlines all prioritization methods and results
