East Gros Ventre Butte Treatment & Process:
On September 28
, 2017, the pilot program launched with the first-ever aerial spraying with herbicide to mitigate invasive species in Teton County. Application was performed by a low-flying helicopter eliminating the “drift” by taking advantage of the helicopter’s rotor wash to effectively push the herbicide to the ground. Combined with support and excitement from Teton County residents, the Jackson Hole Weed Management Association looked forward to this spring to view the results of the treatment.
Both Bayer Esplanade and BASF Plateau herbicide were chosen for this project to combat cheatgrass. “Based on effective treatment in other test areas which resulted in no signs of impact to native vegetation, wildlife, or people we anticipated the cheatgrass mitigation pilot project would be successful”, said Mark Daluge, Teton County Weed and Pest Assistant Supervisor.
