Northwoods Cooperative Weed Management Area

About Us

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.


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. 

Range of the Northwoods Cooperative Weed Management Area

The Northwoods CWMA includes the four counties that border Lake Superior in Wisconsin:  Ashland, Bayfield, Douglas, and Iron Counties.  Here is a map of this area.

Our Mission
Working together to protect northern Wisconsin from invasive species.


What We Do

  • Coordinate community work days to control invasive plants

  • Educate the public about invasive species through trainings, presentations, and informational materials

  • Provide technical assistance and equipment

  • Collaborate with agency staff, municipalities, and others on projects

  • Hold regular monthly meetings open to the public


Have Invasive Species on your Property?

The NCWMA can provide technical assistance, such as plant identication and management options for various species. We have a tool shed with tools and equipment available for free public use.


What's the Big Deal?

Invasive non-native plants can have devastating impacts on native plant communities, fish and wildlife habitat, agriculture yields, recreational and subsistence opportunities, and ultimately, local economies. It is estimated that damages from invasive species cost the U.S. 35 billion dollars per year.



Invasive plants disperse widely across the landscape. Effective management requires cooperative efforts across jurisdictional boundaries.


What you can do:

  • LEARN about new and existing invaders.

  • REMOVE, dispose of, and control any invasive plants on your property.

  • PREVENT the spread of plants by removing seeds, mud and plant fragments from clothes, shoes, pets and equipment.

  • PLANT native, non-invasive species when landscaping.

  • JOIN the NCWMA.

  • Have project ideas for us? Let us know!

Our History
The NCWMA started as a small group of staff from different agencies in Wisconsin's Lake Superior region who shared a growing concern about the spread of invasive species in the area.  The group was originally called the Northwoods Weed Initiative. In 2005, they began following the model of Cooperative Weed Management Areas in the western U.S., and formally adopted the name "Northwoods Cooperative Weed Management Area" (NCWMA).  This marked the beginning of an effort to bring in additional members and expand the scope of the group.  By 2007, they had developed a management plan, annual operating plan, and a Memorandum of Understanding (MOU). In 2007, the group secured its first grant and launched a series of programs in pursuit of its mission.  


NCWMA is one of many Cooperative Weed Management Areas (CWMA) and Cooperative Invasive Species Management Areas (CISMA) in Wisconsin.  Learn more about these groups in Wisconsin.
