Wisconsin has no defensible-space wildfire law, but Wis. Stat. 66.0407 requires every landowner to destroy noxious weeds (Canada thistle, leafy spurge, field bindweed and locally designated weeds) on their land. Removal by open burning must still follow DNR NR 429 rules.
Unlike western states, Wisconsin does not mandate wildfire brush-clearance zones. The controlling vegetation rule is Wis. Stat. 66.0407, which makes each person owning, occupying or controlling land destroy all noxious weeds on it. Noxious weeds include Canada thistle, leafy spurge, field bindweed, any weed the DNR designates by rule, and any weed a municipality or county board declares noxious. Towns appoint weed commissioners who may order abatement. Rock County's Land Conservation Division administers related erosion-control and land-management ordinances. If you clear brush by burning, you must still obtain any required burn permit and follow DNR open-burning limits.
Weed commissioners may destroy noxious weeds not abated by the owner and assess the cost to the property (often as a tax lien). Fines are set by local weed ordinances.
