Noxious Weed Control Event Held

Grand Teton National Park

National Park News

The Jackson Hole Weed Management Association hosted the Greater Yellowstone Coordinating Committee’s first-ever noxious weed spray days on July 31st and August 1st.

Nearly 70 volunteers came from all around the Greater Yellowstone Area to team up for invasive weed control at the Laurance S. Rockefeller Preserve and along the Snake River within Grand Teton National Park. Organized by Jason Brengle, vegetation biologist at the 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 Greater Yellowstone Area,” said Mary Cernicek, president of the association. “Working across jurisdictional boundaries for the betterment of the entire ecosystem is what the association and the coordinating committee’s terrestrial invasive species committee are all about.”

Crews treated roughly 14.5 acres of 1,106-acre preserve and about 31 acres along the Snake River. Herbicide spot treatment was used on St. John’s wort on the preserve; mechanical treatment of a variety of invasive plants was the primary method used along the Snake River.

Several local agencies and organizations assisted with the project.

“We were so pleased with the large turnout and all of the hard work that the volunteers contributed,” said Brengle. “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 Greater Yellowstone Area.”

The Greater Yellowstone Coordinating Committee was formed to allow representatives from the National Park Service, US Forest Service, the US Fish and Wildlife Service and the Bureau of Land Management to pursue opportunities for mutual cooperation and coordination in the management of core federal lands in the Greater Yellowstone Area.

Their terrestrial invasive species committee includes invasive species coordinators from each Greater Yellowstone Area unit, county weed and pest staff, BLM, and other state, county and federal weed managers. They 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.
