Cooperative Weed Management Area

The CWMA was formed due to concern of threats to native wetland, and terrestrial systems posed by invasive plant species in Wright County. Currently, Wright County Townships, Wright County Highway and Parks Departments, Minnesota Department of Natural Resources, Minnesota Department of Transportation, Wright Soil and Water Conservation District, and some private landowners have partnered to control the spread of Wild Parsnip and a few other noxious weed species. More participation from private landowners and other entities could improve results long-term.

What is being done?

We continue with what was started in 2008 and work within our cooperative system, to control Wild Parsnip, Common Teasel, Round Leaf Bittersweet, Common Tansy, Leafy Spurge, Non-native Phragmites and Wild Carrot through education, and management options. An annual meeting is held each winter to educate and discuss issues of concern.
