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.


Be on the Lookout for Garlic Mustard Aphids: We are calling all 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. Please see this informational flyer for instructions on how to report your observations. 

2022 Membership Drive: You can help MIPN enact its mission by becoming a member or renewing your membership. All the details are here!

Do you have questions about how to identify or control woody invasive plants? Or about how they are regulated? Visit the website for the Woody Invasives of the Great Lakes Collaborative at Find your answers with WIGL.

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

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.
