Invasive Plant Management Factsheets

The Renz Lab has created a series of factsheets discussing the identification and control of many common invasive plant species problematic to natural areas. Mechanical, cultural, and chemical control methods are discussed in detail, including effectiveness of the control method and appropriate rates and timings of chemical control applications.

Hazardous Plant Identification

The Renz Lab has helped produce a brochure describing the identification of Wisconsin plants that are hazardous to human health, whether through contact or consumption. These plants are often found in natural areas and roadsides, although they may also be found in agricultural settings.
