BLM High Desert District plans to implement cheatgrass treatments

ROCK SPRINGS, Wyo. – The Bureau of Land Management High Desert District Rock Springs Field Office, in coordination with the Sweetwater County Weed and Pest Control District, plans to implement cheatgrass treatments on multiple BLM- managed lands and partner lands during late July, and possibly early August 2025. This is contingent upon weather meeting the required application conditions. The treatments will only be implemented if specified parameters are present.

Aerial application of Indaziflam herbicide (trade name Rejuvra) will potentially occur on the following project:

South of Rock Springs treatment areas include areas of mixed ownership in Greasewood Draw, Currant Creek Ridge, Richards Mountain, and Laney Rim areas. Approximately 11,500 acres of cheatgrass infested foothills and rangelands will be treated.

These projects will manage and remove cheatgrass, an invasive, non-native, early-season annual grass from rangelands to remove competition to important native forage and browse. Cheatgrass treatments manage and mitigate hazardous fuels in the wildland urban interface, including threats to industrial energy infrastructure. These treatments improve vegetation conditions in critical big game habitat and improve forage for livestock.

During operations, application aircraft (rotary-wing, potentially fixed-wing) will be visible within and adjacent to defined project area boundaries at relatively low altitudes. Permittees, oil and gas field personnel, recreationists, and other public land users are urged to be aware of treatment operations.
