Permit information for Chapter NR 40 invasive species

To limit the introduction and spread of invasive species in Wisconsin, the department established Wisconsin's Invasive Species Identification, Classification and Control Rule, Chapter NR 40, Wis. Adm. Code, in 2009. With certain exceptions, it is unlawful for a person to transport, possess, transfer or introduce a "prohibited invasive species" without a permit from the department. It is also unlawful for a person to transport, possess, transfer or introduce a "restricted invasive" fish or crayfish species or transport, transfer or introduce any other "restricted invasive species" without a permit. 

View the full list of species regulated under the rule.

The department may issue permits for research or public display of any listed invasive species. For species other than invasive fish and crayfish, permits may also be granted for additional purposes. Permits are not needed to possess, transport or transfer non-viable specimens.
