Weed Management Areas

Clearwater Basin Weed Management Area
Clearwater Basin South Sub-Basin Weed Management Area
Frank Church Weed Management Area
Joseph Plains Weed Management Area
The Joseph Plains Weed Management Area came into existence in the spring of 2000. Driving the organization were the several large private landowners wishing to take a stand against continued expansion of noxious weeds into valuable grazing and timberlands of the area.

The 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 Weed Management Area. A majority of the lands located within the JPWMA are privately owned. Additional cooperators include the Bureau of Land Management, Cottonwood office, Idaho Department of Lands Craigmont office, Idaho Department of Fish and Game Lewiston Office, and Idaho County Weed Control.

This WMA faces a common problem with the surrounding WMAs in that portions of the land base are currently infested with yellow star thistle. Other weed species that inhabit the area to some extent are Spotted Knapweed, Leafy Spurge, Dalmation Toadflax, Diffuse Knapweed, Italian Thistle, Scotch Thistle, and White Top.

Cooperators are working together to accomplish the following:

  • Categorize weed species into confine, contain, and control/eradicate categories
  • Establish specific weed management objectives
  • Create treatment zones and weed free zones within the JPWMA
  • Coordinate the use of resources and manpower
  • Develope an initial noxious weed inventory and map
  • Implement an integrated pest management approach
Salmon River Weed Management Area
The Salmon River Weed Management Area (SRWMA) has been together since 1994. The Salmon River Weed Management Area (SRWMA) is intended to bring together those responsible for weed management within the Salmon River drainage, to develop common management objectives, facilitate effective treatment and coordinate efforts along logical geographic boundaries with similar land types, use patterns and problem species. A general map of the Salmon River Weed Management Area, with acres summarized by land ownership, is included in the SRWMA plan, linked below. Cooperators include private landowners, county government, state agencies, federal land management agencies, and interested organizations and individuals. Cooperators jointly:

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