Public Gardens as Sentinels of Invasive Plants (PGSIP) Resources: The PGSIP initiative has issued its first Plant Alert, highlighting Amur corktree. PGSIP is a network of public gardens pro-actively identifying non-native plants within their collections that are exhibiting invasive tendencies. We have also created a public data dashboard, so anyone interested in early detection can see the most commonly reported taxa in a given state or region. Watch our new video to learn more and find out how your garden or arboretum can participate.

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 and other land managers. If your business would like to be added to our directory, please fill out our Google form.
Landscape Alternatives – This free mobile app is available for iOS and Android and provides alternatives for over 40 invasive plants found in the Great Lakes region. Search "Landscape Alternatives" in your app store to download. We also have a print version, with alternatives to 13 common invasive plants.
Free Publications: Revegetating with Natives – MIPN worked with the USFS to develop two guides on revegetating with native plants to ward off invasives; one for homeowners and one for natural area managers. Download accessible pdfs free here or customize and co-brand these as outreach materials here.
