BLM and Sublette County plans to implement cheatgrass treatments
PINEDALE, Wyo. – The Bureau of Land Management Pinedale Field Office, in coordination with the Sublette Country County Weed and Pest Control District, Forest Service and the State of Wyoming, plans to implement cheatgrass treatments on multiple BLM-managed lands, partner and private lands throughout the county starting July 15. Treatments depend on weather conditions meeting application requirements.
The Sublette County Weed and Pest’s aerial contract applicator will treat areas along the Wind River front and Wyoming Range daily through August, using multiple helicopters.
The roads leading to active treatment areas will be marked in the field with signs. Please avoid these active treatment areas to allow for work to continue. Updates will be posted weekly on the Sublette County Weed and Pest facebook page.
Cheatgrass, a non-native invasive annual grass, competes with native vegetation for resources. It grows in the interspace between native plants where it competes for resources, causes an increase in fine fuels and fire frequency, and changes the landscape for sagebrush obligate species, and reduces grazing opportunities. This treatment is part of a large-scale landscape level project to control cheatgrass and limit its spread, protecting native vegetation.
Treatments are a part of an ongoing project of the Sublette Invasive Species Taskforce managing cheatgrass. 2025 treatments are a culmination of many years of planning to acquire funding, environmental authority, and permissions. The scale is widespread and across multiple land jurisdictional boundaries. Most treatments occur on south facing slopes.
In the Wyoming Range, treatments generally will occur in the foothills from Black Canyon down through Lake Mountain, the little Colorado Desert and the Calpet Road. On Forest Service managed lands, treatments will be on the ridges and adjacent hillsides of Fremont, Halfmoon and Boulder Lakes. On BLM, north and south of Fremont, Halfmoon, Warren Bridge, Boulder, Scab Creek, Irish Canyon, Muddy Creek, Little and Big Prospect areas and towards Elk Mountain and the Sublette County Line. Along Highway 1919/189 down the rim. State and private lands in these areas will also be treated. The treatments around Silver, Pocket and Cottonwood Creeks will begin August 14 and continue until completed pending favorable weather conditions.
