Noxious Weeds

Understanding Wisconsin’s Noxious Weed Regulations

What Are Noxious Weeds?

Noxious weeds are invasive plant species that threaten agriculture, natural ecosystems,

and property values. These weeds spread aggressively, outcompeting native vegetation

and reducing crop yields.

Wisconsin’s Noxious Weed Law

Under Wisconsin Statute 66.0407, property owners, including government entities, are

required to control the spread of noxious weeds. Local municipalities are responsible for

enforcing this law to protect both agricultural productivity and environmental health.

Responsibilities of Property Owners

Identification & Control: Property owners must identify and manage the presence of

noxious weeds on their land. Methods of Control: Includes mowing, chemical

treatments, hand removal, and prescribed burning where applicable. Penalties for Non-

Compliance: If weeds are not controlled, the local municipality may take action and

charge the property owner for removal costs.

Reporting & Enforcement

If you suspect a property is non-compliant, let us know! We will inspect and notify

landowners of their obligation to remove the weeds. If no action is taken, we may

arrange for weed removal and bill the property owner on their tax bill.
