Who we are
Learn about the goals, people, and work of the King County Noxious Weeds program.
Program staff work with all land managers in the county to reduce the impacts and spread of noxious weeds, with a focus on direct service, efficiency, and technical expertise. Our goal is to help everyone find the best control options for noxious weeds on each site and to reduce the overall impact of noxious weeds throughout the county. Program staff focus on all regions of the county, public lands, aquatic weeds, rivers, conservation lands, and education.
This is who we are.
Regional specialists
King County includes a diverse range of landscapes, from the cascade crest to the shores of Vashon. To support cities and residents in tracking noxious weeds across this landscape, our program has divided the county into regions & focus areas to tailor services to the needs of different communities.
