Jackson, Wyoming (2012): The Jackson Hole Weed Management Association (JHWMA) hosted the first ever Greater Yellowstone Coordinating Committee’s (GYCC) noxious weed spray days on July 31 and August 1, 2012.  Nearly 70 volunteers came from all around the Greater Yellowstone Area (GYA) to team up for invasive weed control in the Laurance S. Rockefeller Preserve and along the Snake River within Grand Teton National Park.  Organized by Jason Brengle, vegetation biologist at Grand Teton National Park, the group targeted St. John’s wort, hound’s-tongue, and musk thistle, all invasive weeds that compete with native vegetation and adversely impact wildlife habitat.

“This was a great opportunity to team up with partner organizations and highlight the importance of managing invasive species across the GYA”, said Mary Cernicek, JHWMA President.  “Working across jurisdictional boundaries for the betterment of the entire ecosystem is what the JHWMA and the GYCC Terrestrial Invasive Species Committee are all about”.

Crews treated roughly 14.5 acres of over a little more than a thousand acre area at the Laurance S. Rockefeller (LSR) Preserve and about 31 acres along the Snake River. In the LSR herbicide spot treatment occurred on St. John’s wort while mechanical treatment of a variety of invasive plants was the main treatment method along the Snake River.

Agencies and organizations that assisted with the project are:

Teton County Weed and Pest, Natrona County Weed and Pest, Sublette County Weed and Pest, the Bridger-Teton National Forest, Caribou-Targhee National Forest, Beaverhead-Deerlodge National Forest, Shoshone National Forest, the National Park Service’s Northern Rockies Exotic Plant Management Team, National Elk Refuge, Teton Science School, the University of Wyoming, Triangle X Ranch, and Hold the Line.

“We were so pleased with the large turnout and all of the hard work that the volunteers contributed.  We hope this will become an annual event that will rotate around the ecosystem each summer, allowing the federal, state and county agencies, as well as private stakeholders, to team up, help one another, and collectively reduce the spread of noxious weeds in the GYA,” said Jason Brengle.

The GYCC Terrestrial Invasive Species Committee includes invasive species coordinators from each GYA unit, county weed and pest staff, BLM and other state, county and federal weed managers who work together on the creation of common inventories, establishment of cooperative weed management areas, promotion of best management practices, and development of education and information materials and integrated management plans to manage and prevent the spread of noxious weeds.
