If the weed species is on the list of regulated noxious weeds in King County, Washington, we will follow up with the property owner or government agency responsible to help make sure the weeds are controlled. If the weed species is not regulated (meaning that control is not required under the state noxious weed law), the information is still helpful for us to have so we can understand more about the distribution and impacts of all noxious weeds in King County.

For more information, please contact our office by email at noxious.weeds@kingcounty.gov or by phone at 206-477-WEED (206-477-9333), or visit our home page for more resources.

Thank you for helping us locate noxious weeds.
