November 2015: Japanese knotweed control: It takes a community

Japanese knotweed, now a state prohibited plant, is spreading explosively in some areas of southern Michigan. Due to its attractiveness in flower and former intentional planting in many landscapes as a cultivar, the insidiousness and particular challenges of managing this plant are often not recognized until infestations are extensive. Common first approaches like using over-the-counter herbicides and pruning or mowing can actually stimulate its spread. Effective treatments for Japanese knotweed ARE available and involve a combination of community and municipality education and using the right herbicides at the right time. We will present lessons learned and successes in managing Japanese knotweed in Ingham and Clinton Counties, which have taught us how to manage other invasive species more effectively, too!

Dr. Leslie Kuhn - Field Projects Coordinator and Co-founder, Mid-Michigan Stewardship Initiative. Successes include partnering with MDNR, Ingham County Parks, Meridian Township and private landowners to acquire and protect 120 acres of woods and wetlands in the Lake Lansing area. Mid-Michigan Stewardship provides public workshops and demonstration native gardens, and is currently working with 104 different private, commercial and municipal landowners on our regional Phragmites, Japanese knotweed, and swallow-wort control projects (including real estate companies DTN and Eyde; ITC Transmission Line Co; MDOT; MSU; Meridian Township Parks, Land Preservation Advisory Board, and Public Works; Lake Lansing Special Assessment District/ Watershed Advisory Committee; East Lansing Parks and Public Works; Lansing Parks; MDNR Rose Lake State Wildlife Area; Wild Ones; several neighborhood associations, and the Road Commissions in Ingham, Clinton, and Shiawassee Counties). Dr. Kuhn received her Ph.D. in Biophysics from the University of Pennsylvania, followed by a postdoctoral fellowship in structural biology and molecular design at The Scripps Research Institute in La Jolla, CA. As Professor of Biochemistry & Molecular Biology at Michigan State University, Dr. Kuhn collaborates on blocking pheromone reception in the invasive sea lamprey and Asian longhorned beetle, and reducing the allelopathic effects of garlic mustard to enhance the restorability of natural areas.
