Working Together to Protect Northern Wisconsin from Invasive Species

The Northwoods Cooperative Weed Management Area (NCWMA) is a

collective group of state and federal agencies, municipalities, tribes, nonprofits, community organizations, and individuals who have come together to combat invasive species in Douglas, Bayfield, Ashland, and Iron counties in northern Wisconsin.  Anyone can participate!


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.


The Northwoods Cooperative Weed Management Area provides a forum to share information and resources, collaborate on planning, and cooperate on invasive species management in northern Wisconsin.  Learn more about us and check out our upcoming events!
