Frank Church-River of No Return Wilderness (FC-RONRW), Cooperative Weed Management Area

The FC-RONRW CWMA was formed in the spring of 2003. The “Signing Parties” to this CWMA are: Custer, Idaho, Lemhi and Valley Counties; Idaho Departments of Lands, Fish and Game, and Transportation (Division of Aeronautics); the University of Idaho; the Nez Perce and Shoshone-Bannock Tribes; and the Bitterroot, Payette, Nez Perce and Salmon-Challis National Forests. The majority of area within the CWMA is managed by the Bitterroot, Payette, Nez Perce and Salmon-Challis National Forests as designated wilderness. The boundary of the FC-RONRW CWMA is primarily the existing wilderness boundary. The CWMA boundary also encompasses various corridors and in holdings, and adjacent tracks of non-wilderness National Forest lands to the northwest and to the southwest. Intermingled private lands and lands owned by Idaho Department of Fish and Game and the University of Idaho are found within the boundaries of the FC-RONRW. 

The purpose of the FC-RONRW CWMA is to bring together groups and individuals responsible for and interested in weed management within the FC-RONRW. The primary goal of the CWMA is to promote efficient and effective integrated weed management across the FC-RONRW. Specifically the stated goals of the CWMA are to:

  • Prevent the introduction, reproduction and spread of invasive weeds into and within the FC-RONRW.
  • Reduce the extent and density of established invasive weeds to a point that impacts to wilderness resources is minimized.
  • Maintain and protect existing native plant communities.
  • Implement economical and effective weed control methods for the target weed.
  • Implement an integrated management system using appropriate treatment methods authorized by the 1999 Environmental Impact Statement (EIS).
  • Rehabilitate priority areas following treatment to reduce the susceptibility of reinvasion.
