Cheatgrass treatments to begin in Bridger-Teton National Forest

AFTON, Wyo. (KIFI) - Aerial operations to control and eradicate cheatgrass infestations within the Star Valley Front of the Bridger-Teton National Forest could begin as early as August 7, 2023. 

Aerial treatments are expected to occur along south facing slopes of the Forest from Alpine to Salt Pass and include Big Ridge.

Treatments will occur via helicopter using the herbicide, Rejuvra. All treatments will occur via label direction and according to the Forest Plan and Environmental Impact Statement for Invasive Plant Management for the Bridger-Teton National Forest. Total acres to be treated are not expected to exceed 2,500 acres. No treatments will occur at or adjacent to waterbodies. Treatments will be accomplished via a participating agreement with Lincoln County Weed and Pest.

The intent of the project is to restore, maintain, and enhance habitat within the Greys River Ranger District currently infested with this annual invasive or threatened by this invasive.

Cheatgrass (Bromus tectorum) germinates in autumn which makes treatment in August imperative. This invasive grass outcompetes native forbs and grasses for water and nutrients. This significantly diminishes the quality of wildlife habitat, especially in the critical mule deer and bighorn sheep winter range.
