Cooperative Weed Management Area Program (CWMA)
Noxious Weed Inventory Is Now Complete!
The noxious weed inventory for Pennington County has been completed and can be found HERE. Common Tansy is more abundant on the eastern half of the county while Canada Thistle and Spotted Knapweed are more dominant on the western half.
It is important to know what noxious weeds are present in your area and know which methods of control are the most effective. If you choose to mow noxious weeds, do so prior to seed development and DO NOT mow when seed is present. To dispose of noxious weeds, it is best to let the plant lay and decay. Transporting plants could accidentally spread the weed to new locations and burying the plant parts could allow regeneration.
For more information on weed management, or you would like report infestations of noxious weeds, please contact the Pennington CWMA (218-683-7075) or the Pennington County Agricultural Inspector.
