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.


2022 Membership Drive: You can help MIPN enact its mission by becoming a member or renewing your membership. Note that MIPN Members are eligible for a $30 discount on UMISC registration. All the details are here!

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 May 2022 we put out the call for citizen scientists to be on the lookout for garlic mustard aphids (Lipaphis alliariae). These garlic mustard specialists, originally from Europe, were recently detected by staff at Holden Forests and Gardens. 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. During this first reporting season, a total of 72 reports were submitted, including 39 positive reports of garlic mustard aphids from 4 states in MIPN's area of coverage Ohio, Michigan, Wisconsin, and Minnesota. Reports were also submitted from Massachusetts, and Connecticut. See our informational flyer for more information.

Resources to Locate Native Plant and Ecological Service Providers in the Midwest Click here to access two new 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.
