CONTROL & MANAGEMENT

*Click Here* for MIPN's Invasive Plant Control Database

Check out our database of control techniques, which compiles and ranks the effectiveness of control methods for many invasive plants common to the Midwest. Information in the database reflects scientific literature review, consultation with experts in the field, and user input. In fact, if you have experience controlling any of the species listed below, you can help improve the database by submitting a case study. Each case study includes details about the control method used, the specific location treated, and the effectiveness of the treatment. We are happy to receive case studies for methods included in the database that either support or counter the effectiveness ranking in the database, and we are happy to receive case studies for methods not currently included in the database as well. The project is the result of a partnership between MIPN and the Weed Science Program at the University of Wisconsin-Madison's Cooperative Extension.

Plants included in the database are:

Amur honeysuckle
Asian bittersweet
Autumn olive
Bird's-foot trefoil

It synthesizes scientific information, addresses plants of concern by bioregion, and discusses emerging issues.

Best Practices Handbook for Roadside Vegetation Management, Minnesota Department of Transportation, 2008 (pdf - 5 MB). This handbook describes best strategies and practices for managing roadside vegetation, including management planning, public relations, weed/invasives control, and use of native plant species.

Roadside Revegetation: An Integrated Approach to Establishing Native Plants and Pollinator Habitat, U.S. Department of Transportation, 2017. This technical guide addresses roadside vegetation management based on goals related to pollinator habitat enhancement. In addition to special considerations related to pollinator needs, it includes broadly applicable information on site preparation, weed management, implementation and monitoring.
