Weed Laws

The term "noxious" is a legal term used to describe non-native plants that have been introduced to Washington from other parts of the world. Because of their aggressive growth and lack of natural enemies in the state, these species can be highly destructive, competitive or difficult to control. These exotic species can reduce crop yields, destroy native plant and animal habitat, damage recreational opportunities, clog waterways, lower land values, create erosion problems and fire hazards, and poison humans and livestock.

Cooperation with landowners and the public is integral to the management of noxious weeds. It is the desire of the Lewis County Noxious Weed Control Board that everyone look beyond jurisdictional boundaries and take an active role in the management of noxious weeds and the stewardship of Lewis County. –LCNWCB

Lewis County Noxious Weed Control Board carries out the mandates of the Washington State Weed Law RCW 17.10. The weed law was instituted to control the introduction and spread of invasive, non-native plants. The primary responsibility for noxious weed control is placed on the landowner whether private, State or County lands. For more information see the links below.
