What Are Noxious Weeds?

Noxious weeds are non-native plants introduced to Washington through human actions. 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 and poison humans and livestock.

What Is The State Noxious Weed Law?

Washington’s noxious weed law (RCW 17.10) requires public and private landowners, including city, county, state and federal land agencies, to control and prevent the spread of designated noxious weeds on their property. Control is defined in WAC 16-750 as the prevention of all seed production. Federally owned lands are also subject to the Federal Noxious Weed Act (Public Law 93-629). Since many people are unfamiliar with noxious weeds, the county weed program is available to provide information on identification and control option(s). Landowners can choose the control option(s) they feel is most appropriate for their noxious weed site.

Why Is There A Law To Control Noxious Weeds?

Noxious weeds affect everyone. Weeds do not obey property lines or jurisdictional boundaries. It takes a coordinated effort to prevent new noxious weeds from establishing and to control and eradicate the weeds already here. The noxious weed law provides a tool to quickly and effectively stop the spread of the new and most damaging weeds. Early Detection and Rapid Response is the ultimate goal.

Which Weeds Should Be Controlled?

To help protect the county’s resources, the Lincoln County Noxious Weed Control Board adopts a County Weed List each year (WAC 16-750). This list categorizes weeds into three major classes: A, B and C based on distribution, abundance and level of threat (how dangerous the plant is to humans, animals, private and public lands, and native habitats).

The goal is to prevent the spread of new and recently introduced weeds while it is still cost-effective. Class A weeds are the most limited in distribution and therefore the highest priority for control. Class B and C weeds vary in priority based on local distribution and impacts. Noxious weeds that are widespread in Lincoln County are called non-designated noxious weeds and control of these is also required.

What Is The Role of The Lincoln County Noxious Weed Control Program?

We educate property owners on identification, impacts and control methods for state-listed noxious weeds. It is also our job to locate noxious weed infestations that are not being effectively controlled. To achieve this, the program conducts annual surveys and follow-up checks on existing noxious weed locations.

What Does The County Do When Noxious Weeds Are Found?

Program staff provides the landowner with information on how to identify and control noxious weeds on their property. If requested, we will meet with the owner or property manager to review the weed locations and discuss site-specific noxious weed control plans. We also offer backpack sprayers for rent.

What Will Happen If The Noxious Weeds Are Not Controlled?

We will make several attempts to contact the landowner to achieve control. If there is no control when we return to survey at the specified time, landowners may be issued a Notice of Violation (NOV) giving them 10 days (or 48 hours if weeds are in flower or seed) to control the noxious weeds. If the noxious weeds are not adequately controlled by the end of the NOV time limit, the program is authorized by Washington’s noxious weed law (RCW 17.10) to control the noxious weeds and bill the owner for the cost to control and/or issue a non-traffic Civil Infraction whose penalties are assigned as described in the Schedule of Monetary Penalties (WAC 16-750-020).
