Non-Native Invasive Species on the Chequamegon-Nicolet

weeds logo 2015 nu Non-native invasive species (NNIS) have the capacity to transform or dominate native plant communities. 

Currently, 24 plants have been found on the Forest and are considered species of immediate concern because they are invading native plant communities. An additional 20 species have been identified as invasive and present within the forest, but the invasion in natural communities is uncertain. These are being monitored.

Please note: some documents are very large and may take some time to download.

The “New Invaders” newsletter (pdf) is the Forest’s new approach to inform the public about non-native invasive species treatments.  This is part of the Administrative Change to the 2005 Chequamegon-Nicolet Invasive Plant Control Project made in 2014. Maps and other data can be found here.

Other NNIS News:

On July 7, 2005, a Decision Notice was issued to implement a Forest-wide non-native invasive plant management program within the Forest. The purpose is to prevent the further spread of non-native invasive species (NNIS) into native ecosystems and to keep these sites in their desired condition. This project will integrate several control methods to achieve results.

The NNIS inventory is updated annually. We utilize the newest information on best available treatment methods. We monitor past treatment sites and adapt our methods accordingly. We work with partners across boundaries through Cooperative Weed Management Area groups.
