Celebrate 20th Anniversary with JHWMA


Where have 20 years gone?

  • MOU & Cooperative Agreement finalized in 1999
  • Funding:
    • 2000 – $70,750
    • 2018 – $805,380




The Jackson Hole Weed Management Area (JHWMA) comprises nearly 2,290,000 acres of public and private lands within Wyoming. Approximately 11% of the area is made up of public lands administered by Yellowstone National Park, 15% by Grand Teton National Park, 62% by the Bridger-Teton National Forest, 8% by the Targhee National Forest, 1% by the National Elk Refuge, and less then 1% by the Bureau of Land Management, and the Bureau of Reclamation, combined. The remaining 3% of the area is in state and private ownership primarily in the Jackson Hole area. The general area is commonly know as the Greater Yellowstone Area and for the most part, the area is defined as the South Fork of the Snake River watershed including all of its tributaries within the State of Wyoming. The watershed begins at its headwaters in Yellowstone National Park and ends in the Snake River Canyon at the Wyoming/Idaho border (see map Appendix A).

This area has been acclaimed as one of the most intact and important ecosystems in the United States. It hosts world renowned flora and fauna, Wilderness areas, National Parks, threatened plant and wildlife species, and the nationally acclaimed Jackson Hole resort area. These unique attributes have attracted millions of people and development to the area. Unfortunately this growth and use has brought with it an invasion of noxious weeds which are now a significant threat to the economy and ecosystem.


The purpose of the Jackson Hole Weed Management Association is to establish common long and short-term management policies, goals, and objectives necessary for cooperatively managing and funding noxious weed activities across all jurisdictional boundaries in the JHWMA. Cooperators include federal, state, county, and private land management agencies as well as other interested organizations and individuals.  This mutual aid approach to weed management will insure that the maximum efficiency and effectiveness for prevention and control is realized.
