Controlling Invasive Species
Nonnative and invasive species can alter ecological relationships among native species and can affect ecosystem function, economic value of ecosystems, and human health. Successful pest management effectively controls the infestation and spread of nonnative and invasive animal and plant species.

Insect & Plant Control
Wisconsin’s Invasive Species Identification, Classification and Control Rule, Chapter NR 40, Wis. Adm. Code helps citizens learn to identify and minimize the spread of plants, animals and diseases that can invade our lands and waters and cause significant damage. The Chapter NR 40rule creates a comprehensive, science-based system with criteria to classify invasive species into two categories: "Prohibited" and "Restricted." With certain exceptions, the transport, possession, transfer and introduction of Prohibited species is banned. Restricted species are also subject to a ban on transport, transfer and introduction, but possession is allowed, with the exception of fish and crayfish.
The Southeastern Wisconsin Invasive Species Consortium
The Southeastern Wisconsin Invasive Species Consortium (SEWISC) is a broad-based coalition that promotes efficient and effective management of invasive species throughout an eight-county region.

- The University of Wisconsin’s Weeds Information website provides useful information to the public that is specific to weedy plants of the midwest; specifically Wisconsin. You can use known traits to search for and identify 280 of the most common weeds of Wisconsin.
- A YouTube video series that provides key characteristics for the identification of invasive plants listed in Wisconsin’s invasive species administrative rule Chapter NR 40 (PDF).
- The Great Lakes Early Detection Network is a collaboration among multiple stakeholders working to rapidly respond to new invasive species sightings in the Great Lakes states (Minnesota, Wisconsin, Illinois, Indiana, Michigan, Ohio, Pennsylvania, and New York). To accomplish this, they have developed a web-based alert system that emails users when new sightings for species or areas of interest are reported and verified.
