Current through June 24, 2024
(1) CLASSIFICATION CATEGORIES. For purposes
				of this chapter, invasive species are classified into the following categories:
				prohibited and restricted.
Note: For informational and educational purposes, the
				  department informally maintains and updates as needed a caution list of
				  invasive species and a list of non-restricted invasive species. Caution list
				  invasive species are either not found in the state, or if they are, the extent
				  of their presence or impact is not sufficiently documented. Caution list
				  species may have shown evidence of invasiveness in similar environments in
				  other states and could potentially spread in Wisconsin. Unlike the prohibited
				  and restricted categories, caution list category invasive species are not
				  regulated under this chapter. Additional information is needed to determine if
				  caution list species belong in another category. Any person finding a caution
				  list species or knowing of its spread or lack thereof is encouraged to report
				  the location, spread and impact (if known) to the department and to contain the
				  spread of the species. Any person selling or distributing a caution list plant
				  species is encouraged to distribute educational materials asking that the
				  plants not be planted near wild, natural or environmentally sensitive areas.
				  Non-restricted invasive species may have beneficial uses, but they also may
				  have adverse environmental, recreational or economic impacts or cause harm to
				  human health. Most of the non-restricted species are already integrated into
				  Wisconsin's ecosystems, and state-wide control or eradication is not practical
				  or feasible. Non-restricted category invasive species are not regulated under
				  this chapter. All other non-native species recommended for listing as invasive
				  but not yet assessed for this rule are put on an informal pending list. Future
				  rule revisions will involve assessing some species from this list.

				  list may be obtained at no cost at

(2) CRITERIA. The department shall consider
				the following criteria in classifying a nonnative species as an invasive
				species for the purpose of this chapter:
(a)
				The species' potential to directly or indirectly cause economic or
				environmental harm or harm to human health, including harm to native species,
				biodiversity, natural scenic beauty and natural ecosystem structure, function
				or sustainability; harm to the long-term genetic integrity of native species;
				harm to recreational, commercial, industrial and other uses of natural
				resources in the state; and harm to the safety or well being of humans,
				including vulnerable or sensitive individuals.
(b) The extent to which the species is
				already present in the state, or in portions of the state, including whether
				there are isolated pioneer stands.
(c) The likelihood that the species, upon
				introduction, will become established and spread within the state.
(d) The potential for eradicating the species
				or controlling the species' spread within the state, including the
				technological and economic feasibility of eradication or control.
(e) The socio-economic value afforded by the
				species, including any beneficial uses or values the species may provide for
				recreation, commerce, agriculture or industry within the state.
