*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

Management Handbooks

Managing Invasive Plants: Concepts, Principles, and Practices, U.S. Fish and Wildlife Service, 2009. This modular training guide provides an overview of the scientific and management concepts that underpin successful invasive plant management. It includes case studies, quizzes, references to scientific literature, and links to other web-based resources.

Integrated Vegetation Management Handbook - H-1740-2, United States Bureau of Land Management, 2008. (pdf - 5 MB). Integrated vegetation management is the practice of integrating multiple invasive plant management and revegetation strategies to meet plant community management goals. Although this guide focuses on the specific program elements used by BLM, many of the approaches are broadly applicable.

Weed Control Management Handbook: Tools and Techniques for Use in Natural Areas, The Nature Conservancy, 2003 (pdf - 1.5 MB). This guidebook includes overviews and important considerations for a number of invasive plant control and natural area management methods, including physical removal, grazing, prescribed fire programs, biological control and herbicide use.

Identifying and Managing Aquatic Vegetation - APM-3-W, Purdue Extension, 2009 (pdf - 2.5 MB). This guide discusses ecological problems caused by an over-abundance of aquatic vegetation and provides information on aquatic invasive plant identification and control methods. 

Targeted Grazing: A natural approach to vegetation management and landscape enhancement, University of Idaho, 2006 (pdf - 11.5 MB). Targeted gazing, also known as prescribed grazing, is the strategic employment of livestock to meet land management objectives. This guidebook describes the basic framework and considerations for the use of grazing as a tool to control unwanted vegetation. 

Wildland Fire in Ecosystems: Fire and Non-Native Invasive Plants, U.S. Forest Service, 2008 (pdf - 14.5 MB). This guide explores the use of prescribed fire as a management tool for nonnative invasive plants. 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.
