Non-Native Invasive Species on the Chequamegon-Nicolet

Non-native invasive species (NNIS) have the capacity to transform or dominate native plant communities. Although these "weeds" may be found anywhere, disturbed areas tend to be more susceptible to invasion and retention of many weed species. Activities that disturb the ground, such as road and trail building or skidding timber create an environment that encourages establishment invasive non-natives. Seeds arespread via equipment and motor vehicles, humans, animals, and wind.

Currently, 20 of these plants have been found on the Forest and are considered species of immediate concern because they are currently invading native plant communities on the forest. An additional 10 species have been identified as invasive and present within the forest, but the invasion in natural communities is uncertain. These are being monitored.

The Chequamegon-Nicolet has prepared three documents that are "helps" for weed treatments:

On July 7, 2005, a Decision Notice was issued to implement a 10-year Forest-wide non-native invasive plant management program on about 700 sites 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. For more information, see the NNIS Environmental Assessment Page and the NNIS Supplemental Assessment Page
