Pest Management

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 40 rule 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.
