Invasive Plants of the Midwest: Plants that are not native to the Midwest, and which cause (or are likely to cause) harm to environmental, economic, and/or human health.


Emerging Invasive Plants in the Midwest – In the Fall of 2022, MIPN issued a survey to invasive plants experts across our region of Iowa, Illinois, Indiana, Kentucky, Michigan, Minnesota, Missouri, Ohio, Ontario, and Wisconsin and asked them to identify early detection species for the Midwest region. The ten most frequently reported species are highlighted HERE, along with information about which species are of greatest concern to each individual state/province. You can also check out our Invasive Plants of the Future Midwest page that will connect you to tools in EDDMapS (and tutorials on how to use them) that predict range shifts of terrestrial invasive plants and what they tell us about potential future invaders of the Midwest. 

Attention Public Garden Staff: Public gardens and arboreta can play a unique and pro-active role in assessing which non-native plants exhibit invasive tendencies. The Public Gardens as Sentinels of Invasive Plants (PGSIP) project is building a collaborative network of public gardens to lead on this issue. Learn more and find out how your garden can participate

Update on Garlic Mustard Aphids: In 2022 we asked you to be on the lookout for garlic mustard aphids (Lipaphis alliariae) after these garlic mustard specialists, originally from Europe, were detected by staff at Holden Forests and Gardens in Ohio. Because these aphids may help control invasive garlic mustard plants, there is an effort to map their distribution. The aphid seems to negatively affect the plants by creating twisted seed pods (siliques) and a wrinkled effect on the leaves. A total of 77 reports were submitted in 2022, including 48 positive reports of garlic mustard aphids from 6 states, including 4 Midwest states: Ohio, Michigan, Wisconsin, and Minnesota. Reports were also submitted from Massachusetts, and Connecticut. This effort will continue in 2023. See our informational flyer for more information.

Updated Invasive Plant List – We finished our 2022 update to our listing of Midwest Invasive Plant Species. Check it out here. This page has a 46 page spreadsheet of invasive plants that indicates how species are categorized by each state/province in MIPN's region, as well as links to available plant lists and regulations for every state/province.

Garlic Mustard in the Midwest: An Overview for Managers – Spring is around the corner. If garlic mustard management is on your to-do list, we recommend reviewing this document. MIPN synthesized recent garlic mustard research and used it to develop recommendations on how to prioritize management and whether/how to conduct large pull events. Download the PDF

Resources to Locate Native Plant and Ecological Service Providers in the Midwest Click here to access two directories intended to promote post-control revegetation with native plants. The directories were compiled by MIPN with support from the US Forest Service and are intended for CWMAs/CISMAs/PRISMs and other land managers.

Landscape Alternatives App – This free mobile app, available for iOS and Android, provides alternatives for over 40 invasive plants found in the Great Lakes region. View and share this informational flier with more information, and search "Landscape Alternatives" in your app store to download. We also have a print version, with alternatives to 13 common invasive plants. To access this Landscape Alternatives brochure, visit our publications page. 

Woody Landscape Alternatives Brochure –  This brochure is designed to help home and business owners choose beautiful alternatives to invasive trees, shrubs and woody vines. Download the pdf free here and learn more about how to order free copies for local distribution at the WIGL website

Free Publications: Revegetating with Natives – MIPN recently worked with USFS to develop two short guides for people looking to revegetate with native plants to ward off invasives; one for homeowners/gardeners and one for managers of larger natural areas. Download the pdfs free here or read about how you can customize and co-brand these as outreach materials here.

UMISC 2022, October 25-27, 2022, Green Bay Wisconsin – MIPN was the Administrative Lead for 2022 Upper Midwest Invasive Species Conference, in partnership with the Invasive Plants Association of Wisconsin and the Minnesota Invasive Plant Advisory Council. This conference has been held biennially since 2008, but this was our first hybrid event. We had 523 total participants. 350 traveled to Green Bay and 173 participated virtually. Attendees came from 18 U.S. states, 3 Canadian provinces, and and even from as far away as Switzerland. We are grateful to all of our sponsors and exhibitors who supported this event, which consisted of 40 sessions, over 160 presentations, 2 workshops, 4 field trips, and 23 poster presentations. We thank our excellent plenary speakers Oneida Nation Chairman Tehassi tasi Hill, Carrie Brown-Lima with the New York Invasive Research Institute at Cornell University, Dr. Greg Ruiz with the Smithsonian Environmental Research Center, and Dr. Ajay Sethi with the University of Wisconsin Madison Public Health Program for sharing their expertise with us. Feedback from the event has been overwhelmingly positive. We look forward to seeing everyone again for UMISC 2024 which will be held in Duluth, Minnesota November 12th - 14th.
