An excellent book is now out on invasive plants of aquatic and wetland habitats of Michigan. The 58-page book can be viewed here. The book includes a pictorial key for identification and species accounts with several photos for each species including the plant in the landscape, flower and other defining characteristics. The field guidebook includes a chart of invasive species by communities and a timeline of the best survey period.
Many of these plants are found in Wisconsin, or may be headed this way, and this book can help guide us in identifying invasive plants for early detection. This guide is a great resource for land managers and educators. Thanks to the Michigan Department of Natural Resources and Environment, Michigan Natural Features Inventory and Michigan State University Extension for producing this field guide. To order the book see their website.
