COVID-19 Update

The King County Noxious Weed Program office is currently closed to the public and employees are working from home. The program is continuing to perform critical noxious weed survey and control work to protect human and environmental health. Noxious weed program staff are available to help through email or by calling 206-477-9333. To learn more about COVID-19, visit kingcounty.gov/covid.

 

Noxious weeds are a danger to our environment and the economy. These introduced species cost our region millions of dollars in lost agricultural production, environmental degradation and added maintenance costs.  Once invasive plants spread to natural areas, they harm native plants and wildlife and can be impossible to eradicate.
