Michigan Invasive Plant Species Accounts

Species accounts are available for a number of plant species that have been noted as invasive or having invasive tendencies in Michigan. Some of these are commonly recognized invasive species such as Garlic Mustard, Purple Loosestrife or Phragmites (Giant Reed). Others are emerging threats in Michigan such as Black Jetbead, Swallow-wort, Water Hyacinth or European Frog-bit. A few, such as Hydrilla and Mile-a-Minute, are not yet in the state but are nearby and considered particularly destructive.

Early detection and eradication of these species is critical in preventing further damage to Michigan's natural areas.

Species Accounts were developed with funding from the Michigan Department of Natural Resources.
