Palouse Cooperative Weed Management Area

The Palouse Cooperative Weed Management Area (Palouse CWMA) is located in the North Central region of Idaho, and it encompasses most of Latah County, some of Clearwater County, and small portions of Benewah and Nez Perce Counties. It essentially is the Palouse River drainage, the Potlatch River drainage, and Elk River drainage. The Palouse CWMA was formed because land ownership in the region varies among large and small private landowners, nonfederal government, and the federal government, and it is extremely intermingled.

The main goals of the Palouse CWMA are:

  • To prevent the introduction, reproduction and spread of noxious weeds and invasive plants in the CWMA.
  • Reduce the extent and density of established noxious weeds and invasive plants in the CWMA to levels that are acceptable.
  • Implement the most economical and effective Integrated Weed Management Programs to control noxious weeds and invasive plants in the CWMA.
  • Use GPS and GIS technology for a noxious weed mapping database and a noxious weed inventory within the CWMA.
  • Educate the public as to the importance of proper weed identification and weed management and control.
