Joseph Plains Weed Management Area - End of Year Report FY 2009

The Joseph Plains Weed Management Area (JPWMA) encompasses approximately 180,000 acres located south of the Salmon River (common boundary with the Tri-State WMA), east of the Snake River, north of the Forest Service boundary, and west of the Salmon River WMA. The majority of land located within the JPWMA is privately owned. Consequently, the role of private landowners in the cooperative efforts of weed control is very large. In addition to private landowners, JPWMA cooperators include the Bureau of Land Management (BLM) Cottonwood office, Idaho Department of Lands (IDL) Craigmont office, Idaho Department of Fish and Game Lewiston office (IDFG), and Idaho County Weed Control. 

The goals and mission of the JPWMA are for cooperators to work together in order to successfully:

  • Establish control priorities
  • Establish specific weed management objectives
  • Create treatment zones within the Management Area
  • Treat individual weed species/infestations
  • Coordinate the use of resources and manpower
  • Develop common inventory techniques and mapping
  • Manage designated noxious weeds with an integrated approach
  • Test the feasibility of new techniques and management strategies
