Midwest Invasive Plant List

Over 270 plant species are listed as invasive, noxious, or pest species in the Midwestern U.S. The following list is a compilation of state law invasive plant lists and DNR invasive plant lists in the MIPN area. The list is alphabetical by Latin name.

Currently Indiana, Ohio and Wisconsin have invasive plant councils that have a scientific assessment process to determine if a plant is invasive. The Indiana, Ohio and Wisconsin "lists" here are taken from these respective organizations.

Links to the appropriate state laws or DNR webpages that contain a state's list of invasive plants are included in the index below. If you are aware of an updated list or amended law please help MIPN out by letting us know (email mipninfo at gmail.com). It is our goal to keep this information as up to date as possible.
