Cooperative Weed Management Area Program (CWMA)

Common Tansy

High Landing Township

In 2020, the Pennington Soil & Water Conservation District (SWCD) received a grant from the Minnesota Board of Water and Soil Resources (BWSR) to form a Cooperative Weed Management Area Program (CWMA).  The goal for this program is to create a unified approach to weed management in Pennington County.  We will create a baseline map of the current invasive and noxious weeds in Pennington County in order to prioritize the infestations for proper control and management. Best management practices will be compiled to provide education, outreach, and technical assistance to landowners struggling to control invasive or noxious weeds on their property.  Lastly, we want to start a gravel pit certification program where we can encourage the county, townships, and residents to purchase gravel from the certified pits that are taking action to control the spread of noxious and invasive weeds.


Our next meeting will be held via Zoom Video Conferencing on March 17, 2021, at 1 p.m.  If you would like to join this meeting, please contact Bryanna Grefthen at 218-683-7075 or
