Invasive Species Blitz Program Materials

As you may know, invasive species such as buckthorn, garlic mustard, and wild parsnip pose serious threats to Minnesota’s natural resources, ecosystems, and economy. These materials help new volunteers to join in a statewide effort to tackle the growing problem of invasive species.

The tools in on this page and the links below will help you make a plan to manage invasive species at a site of your choosing and host local invasive plant removal events. You may even wish to adopt a local natural area you can regularly monitor and provide stewardship for into the future.
