Other Priorities Lists
Noxious Weed ListsNoxious weeds are managed by the Washington State Noxious Weed Control Board. The board advises the Washington State Department of Agriculture about noxious weed control in Washington State. It also serves as the state's noxious weed coordination center. Through actions and policy decisions, the board coordinates and supports the activities of the 48 county noxious weed control boards and weed districts of Washington.
Each year, the State Noxious Weed Control Board adopts, by rule (Washington Administrative Code 16-750), the state noxious weed list. This list determines which plants will be considered noxious weeds and where control will be required in Washington State. This approach allows control activities of landowners - both public and private - to be prioritized towards the protection and enhancement of Washington's agriculture and natural areas in the most cost-effective manner.
Class A WeedsNon-native species that are limited in distribution in Washington. State law requires that these weeds be eradicated. To see images of class A noxious weeds, please visit Washington State Noxious Weed Control Board's Class A Noxious Weeds page.
Class B WeedsNon-native species that are either absent from or limited in distribution in some portions of the state but very abundant in other areas. The goals are to contain the plants where they already are widespread and prevent their spread into new areas. To see images of class B noxious weeds, please visit Washington State Noxious Weed Control Board's Class B Noxious Weeds page.
Class C WeedsNon-native plants that already are widespread in Washington State. Counties can choose to enforce control, or they can educate residents about controlling these noxious weeds. To see images of class C noxious weeds, please visit Washington State Noxious Weed Control Board's Class C Noxious Weeds page.
Monitor listPutting plants on the Monitor List allows the state to gather more information about noxious weeds, such as their distribution, observable impacts, spread rate, and more.
