The Minnesota Department of Natural Resources has classified 13 high-risk invasive aquatic plants, fish and invertebrates as prohibited invasive species. The DNR classifies invasive species as prohibited to prevent their introduction and spread in Minnesota and to protect the state’s environment, economy, natural resources and outdoor recreation. It is unlawful to possess, import, purchase, transport or introduce prohibited invasive species, except under a DNR-issued permit for disposal, decontamination, control, research or education.

The prohibition on 12 of the 13 species is effective immediately, with publication of the new listings in today’s State Register. Jumping worms will be prohibited invasive species effective July 1, 2024, to provide additional time for outreach to businesses and others who may be impacted by the rule change. A complete list is available on the DNR invasive species laws website.

To determine which pests posed immediate threats, MITPPC undertook an expansive evaluation process. It convened 15 expert panelists, who ultimately identified 124 significant invasive species threatening our state. This panel also identified 17 criteria that could be used to rate species in an objective, computerized ranking system. Criteria included factors like environmental and economic impact, ability to establish and spread and proximity to the state. Rankings are updated regularly, no later than every other year or as new threats emerge on a more urgent basis. The full whitepaper, Minnesota's Top Terrestrial Invasive Plants and Pests for Research: An Expanded Prioritization [Jan 2020; PDF, 3.64 MB], outlines all prioritization methods and results.

In September 2016, Palmer amaranth, Amaranthus palmeri, was found in Minnesota. To date, it has been documented in Douglas, Jackson, Lyon, Redwood, Todd, and Yellow Medicine counties. The Minnesota Department of Agriculture (MDA), University of Minnesota Extension, USDA, landowners and other partners are working to eradicate these infestations before they can spread to new areas. Be proactive and prevent Palmer amaranth establishment. Familiarize yourself with Palmer amaranth identification and actively look for it in crop fields, borders, ditches, conservation lands and around dairies. If you suspect Palmer amaranth on your property, immediately call your local U of M Extension Educator or IPM Specialist, crop consultant and/or the MDA’s Arrest the Pest (888-545-6684) to report locations.
