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 invastion and ret ention 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 are spread 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.

July 7, 2005. Forest Supervisor Anne Archie has issued a Decision Notice and Finding of No Significant Impact to implement a 10-year Forest-wide non-native invasive plant management program on about 700 sites within the Forest. The purpose of the action 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. This decision is not subject to appeal pursuant to 36 CFR 215.12.

NNIS Events:

The Chequamegon-Nicolet National Forest hosted a Cooperative Weed Management Area Workshop in May at the Northern Great Lakes Visitor Center in Ashland, Wisconsin. The term CWMA refers to a local orgainzation that integrates all noxious weed management resources across jurisdictional boundaries in order to benefit entire communities.
