The Listing Process for the Washington State Noxious Weed List

Every year, the Washington State Noxious Weed Board adopts a new Noxious Weed List (WAC 16-750).

  • Weed species may be added or removed, the Class (A,B,or C) can be changed, or the required control area of a Class B Designate may be changed.
  • The Noxious Weed Committee meets several times a year to review and discuss proposed changes, and they present their recommendations at the November Board meeting so that the Board can make a well-informed decision.

Anyone in Washington state can request that a plant species be added or removed from the Noxious Weed List.

  • To submit a request, you should provide the following information:
    1. The common and scientific name of the plant species, if known
    2. The specific change request (addition, removal, class or designation change)
    3. The reason why you are requesting the change.
    4. It is very helpful if you can also provide any background information, for example, its distribution in Washington (where, when, and how much), and any biology or ecology about the plant
    5. Whether there have been any attempts to control the plant.
    6. Any plant samples or pictures, or any literature or links to web pages about the plant are also very useful.
  • You can download the document explaining how to submit a report here.
  • The request must be submitted between November and April for consideration.
  • You can see the calendar for the listing process here.
