Invasive non-native plants can have devastating impacts on fish and wildlife habitat, timber and agricultural yields, recreational opportunities, native plant communities, and local economies. Garlic mustard, purple loosestrife, Phragmites, giant and Japanese knotweed, common and glossy buckthorn, non-native honeysuckles, leafy spurge, and Eurasian water milfoil are species targeted by the NCWMA.
Because these invasive plants disperse widely across the landscape and across property boundaries, it makes sense to work together to manage them. In addition, the number of new invasive species being introduced into local ecosystems continues to out-pace control activities, and is too much for any one agency or person to manage alone.

See the Wisconsin DNR Invasive Species page for more information on terrestrial and aquatic invasive species.
Emerald Ash Borer has now been found in the City of Superior reslulting in a quarantine for Douglas County. See the City's EAB page for more information.
Another new invader to northwest Wisconsin has been found in SW Ashland County, Japanese hedge-parsley. If you find any evidence of this plant or the emerald ash borer, please contact us.
