Invasive species identification, classification and control. This is the DNR administrative code. Regulation includes the movement of invasive plants or their seeds, either intentionally through planting or unintentionally through construction, mowing or other operations. To comply with NR 40, the need to control themovement of invasive plants and their seeds is essential.

ProhibitedNo person may transport (import/move) possess transfer (buy/sell) or introduce a prohibited
species without a permit.
The DNR may order or conduct the control effort.
RestrictedNo person may transport (import/move), transfer (buy/sell) or introduce a restricted
species without a permit.
Control encouraged but not required.
May possess or transport for control and disposal purposes
Permits may be available for certain cases Transport, possession, transfer or introduction NOT
considered a violation if the Department determines the action was incidental or unknowing AND the person took “reasonable precautions”

Generally, it recommends: Adhering to species specific mowing time
guidelines Not mowing heavily infested invasive
species areas when seed is mature or will ripen after being cut
Cleaning off mower decks and other seed collection
Clean boots off

“Round 1” – 2004 – 2009Included the species that were listed when the rule was established were widely recognized invasive species with little commercial value. Currently 64 regulated terrestrial invasive plants
“Round 2” – 2012 – 2015NR40 enforcement protocols are established, the process for including stakeholders has been tested, and some species proposed for listing have some level of commercial use.
Proposed 52 terrestrial invasive plants

Current Mowing
They are identified as roadways having all of the following attributes: Not a designated connecting highway Right of way within a municipality designated as a municipal extension. Roadway defined as curb and gutter sections and medians Highways with a speed limit of 50 mph or less
37
Urban STH Defined
They are identified as having all of the following attributes: Location inside a state defined MPO or within a state defined “Premier Resort Area,”
per s. 66.1113, Wis. Stats. Part of a controlled-access highway (Interstates, freeways, and freeway/expressway
mixes) The AADT on two interchange ramps is 5,000 or greater per ramp or the AADT on at
least one interchange ramp is equal to or greater than 7,500.
Urban Controlled-access Highway Interchanges and Access Roads Defined

Premier Resort Area
A political subdivision whose governing body enacts an ordinance or adopts a resolution under s. 66.1113(2)(a), Wis. Stats. Wisconsin law permits a municipality or county to impose a “premier resort area” tax if the municipality or county meets certain criteria as described in s. 66.1113, Wis.Stats.
Which municipalities have adopted the premier resort area tax?
The Village of Lake Delton The City of Wisconsin Dells The City of Bayfield The City of Eagle River
Prohibited Invasive Species Not yet in the state or only in a few
places Likely to cause environmental or
economic harm Eradication and prevention is feasibleRegulations: Cannot transport, possess,
transfer, or introduce without a permit. Control is required. DNR may order or conduct a control effort.
