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. Jumping worms will be prohibited invasive species effective July 1, to provide additional time for outreach to businesses and others who may be impacted by the rule change.

  • Jumping Worms have negative impacts on plants and soils. Jumping worms have been confirmed in some Minnesota urban areas but not in most of Minnesota.

  • Non-native Common Reed reduces biological diversity by crowding out native plant and animal species. The rule does not apply to Minnesota’s native subspecies of common reed.
  • Mitten Crabs, Nile Perch, Snakehead Fish, and Walking Catfish are now classified as prohibited invasive species in Minnesota due to their environmental impacts and for consistency with the federal injurious wildlife species list.

  • Yellow Floating Heart (an aquatic plant), Tench (a fish), Golden Mussel, and Marbled Crayfish are all identified as “least wanted” species by the Conference of Great Lakes and St. Lawrence Governors and Premiers Aquatic Invasive Species Task Force.
  • Golden Clams can block water intake pipes and interfere with environments needed by native species. Populations of golden clams have been found in some Minnesota waters.

  • Tubenose Gobies are non-native to North America and have the potential for negative impacts.
  • Eastern Mosquitofish. Eastern mosquitofish have been stocked for mosquito control in other states in the U.S. and have become invasive in places they were introduced. Eastern mosquitofish are not known to now be in Minnesota.

The DNR has authority to protect Minnesota’s environment, economy and natural resources from potential harm from non-native species of wild animals and aquatic plants.

Other, previously listed, prohibited invasive species in Minnesota include zebra mussels, Eurasian watermilfoil, silver carp, and European wild boar. You can see Minnesota's full list here.

LOOK: The states with the most UFO sightings

For each state, we’ve also included details of famous UFO sightings in that state. Of note is that almost three-quarters of all UFO sighting reports in the United States occur between 4 p.m. and midnight, and tend to peak between 9 and 10 p.m. Food for thought next time you're out scoping for alien life. Keep reading to see which states have had the most UFO sightings.

LOOK: The most expensive weather and climate disasters in recent decades

Stacker ranked the most expensive climate disasters by the billions since 1980 by the total cost of all damages, adjusted for inflation, based on 2021 data from the National Oceanic and Atmospheric Administration (NOAA). The list starts with Hurricane Sally, which caused $7.3 billion in damages in 2020, and ends with a devastating 2005 hurricane that caused $170 billion in damage and killed at least 1,833 people. Keep reading to discover the 50 of the most expensive climate disasters in recent decades in the U.S.
