The Top 20 Invasive Plant Species in Northwest Michigan
The Top 20 Least Wanted Species, a list developed by ISN partners in October 2010, consists of those plants that pose the greatest threat to our region’s high-quality natural areas. Half the species listed below were imported for use in landscapes. For identification assistance, visit the Midwest Invasive Species Information Network. For control advice, visit either the Michigan Department of Natural Resources or the Midwest Invasive Plant Network Control Database.
