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.
