Upper Snake River CWMA

Together we can make a difference

The Upper Snake River Cooperative Weed Management Area (USRCWMA) is 

 comprised of Bonneville, Jefferson and Bingham County in partnership with the

 state and federal agencies that manage lands within those counties. The

 USRCWMA provides a forum to coordinate area wide activities to detect,

 prevent, contain, control, and eradicate noxious weeds on public and private

 lands. In the USRCWMA, we believe that sharing funds, equipment, staff, and

 ideas across jurisdictional boundaries in a coordinated and cooperative weed

 fighting strategy will result in more effective "on-the-ground" weed control. 

 The USRCWMA  supports an area wide integrated noxious weed control

 program that uses all available tools and techniques  to combat noxious

 weeds. A steering committee provides the local leadership. 

  Noxious weeds of major concern include Leafy Spurge, Spotted Knapweed, Diffuse Knapweed, Russian Knapweed, Canada

  Thistle, Musk Thistle, Plumeless Thistle, Hoary Cress, Dalmation and Yellow Toadflax, Purple Loosestrife, Dyer’s Woad,

 Rush Skeletonweed,  Houndstounge and Tamarisk.  The rapid spread of these noxious weeds is a serious threat to the

  ecology and economy of eastern Idaho.

  The USRCWMA places a high priority on:

• Developing a coordinated area-wide information and education program.

• Initiating a noxious weed-mapping program using GPS and GIS technology.

• Targeting and funding large scale weed treatment initiatives as well as smaller projects.

• Implementing a research and monitoring program to locally evaluate the effectiveness of weed fighting techniques.

• Early detection and rapid response to new infestations.
