Noxious Weed Control

Noxious Weeds Are a Serious Problem in Washington State

Noxious weed refers to invasive or non-native plants in Washington that are so aggressive they harm our local ecosystems or disrupt agricultural production. These plants crowd out the native species that our livestock, fish, and wildlife depend on. They also cost farmers billions of dollars in lost production and control efforts. Noxious weeds are both terrestrial and aquatic and include non-native, invasive plants, shrubs, and trees that grow both on land and in wetlands, lakes, shorelines and streams. Noxious Weeds can be aggressive in growth. Most of these plants often cause adverse health effects when ingested or touched by humans or animals.

Washington’s State weed law established the State Noxious Weed Control Board, and authorized counties to establish County Noxious Weed Control Boards. Under Washington State law, Landowners are required to control or eradicate noxious weeds on their land or property (RCW 17.10, RCW 17.10.140, etc.).

Why Control Noxious Weeds?

Noxious weeds are non-native plants that can be toxic, destructive, competitive and difficult to control once established.

Economics – Noxious weeds cost the United States on average $30.6 billion each year in decreased land value, money and time spent on control efforts, lower crop yields, reduced forage quality and impacts on animal health.

Environmental health – Noxious weeds displace native species, destroy natural habitat, clog waterways and increase erosion and fire risk.

Human and animal health – Many noxious weeds are toxic to humans and livestock. Contact or ingestion of some species can lead to serious health problems or even death.

Recreation – Noxious weeds hurt recreation opportunities, such as bird watching and fishing, through reduced accessibility and destruction of native landscapes.

Legal – Washington State laws, RCW 17.10.140, requires landowners to eradicate Class A noxious weeds that have limited distribution across the state and to control and prevent the spread of Class B noxious weeds and Class C noxious weeds.
