Garlic mustard is a non-native, extremely invasive plant that has just begun to show up in the Copper Country. It has been found in six Calumet-Laurium locations and eight other sites in Houghton County, mostly in the Houghton-Hancock area. It is not currently known to be in Keweenaw or Baraga Counties.

Marr will show a 12-minute film titled Stemming the Tide: Garlic Mustard ID and Control. She will explain how to get rid of garlic mustard as well as discuss what not to do with the plants. Marr will also have live garlic mustard plants for people to look at plus various brochures about invasive species including garlic mustard. She will also talk about a short field trip to a garlic mustard site in Laurium.
Second-year leaves of the invasive garlic mustard are heart-shaped to triangular, 1-3 inches wide, coarsely toothed on the edges. They give off a garlic odor when crushed. (Photo by Steven Katovich, U.S. Department of Agriculture Forest Service)
The best time to find and report garlic mustard is when it’s relatively sparse in our area and eradication is still possible. Please report any suspected garlic mustard plants in Houghton, Keweenaw, and Baraga counties to Janet Marr at 906-337-5529 or firstname.lastname@example.org or call the Houghton Keweenaw Conservation District at 906-482-0214. People may also contact Marr about RRIP-IT-UP, the Rapid Response Invasive Plant Intervention Team of the Upper Peninsula.
Eradicate Garlic Mustard in Michigan’s Upper Peninsula is a new UP-wide garlic mustard eradication program that is funded by a grant from the National Fish and Wildlife Foundation, which includes funding from the US Fish and Wildlife Service.
