Teton Interagency Fire

The Greys River Ranger District of the Bridger-Teton National Forest plans to implement a 2,000-acre prescribed burn, southern portions of Unit 2B and 2A, in the spring of 2025. Unit 2B and 2A are within Unit 2 of the Star Valley Front Vegetation Treatment Project is located on the Forest Service between Afton and Grover, Wy. Additional units are targeted for implementation this fall. These units include the Unit 9 (Strawberry unit) and unit 8. More information will be shared via a press release when the prescribed burning opportunity becomes available.

The Star Valley Front Vegetation Treatment Project is located east of Star Valley and consists of a 72,577-acre project area with 31,477 acres of proposed burn units extending from Strawberry Creek south to Cottonwood Creek, from the forest boundary to the top of the Salt River Range. The main purpose for treating vegetation in the Star Valley Front Project Area is to begin restoring a balance of age classes in mountain shrubland, mountain big sagebrush, aspen, and conifer communities.

This vegetation treatment is a cooperative effort between the U.S. Forest Service, Wyoming Game & Fish Department, Wyoming Wildlife and Natural Resources Trust, and other partners.

Packsaddle prescribed burn is located in the La Barge drainage between Forest road 10138 and Forest road 10128. This prescription will target 477 acres. Prescribed burning is planned for fall implementations.

Beginning spring of 2025, north zone fuels staff plans to begin implementation of Munger Mountain Prescribed Fire Unit (1,663 acres). This unit involves a multi-phase/multi-year approach, treating smaller segments of the overall unit at a time. Unit field work including ongoing monitoring and protection of values through fuels reduction activities will begin onsite this spring and summer. When conditions are met in 2025, fire personnel will begin burning within the unit as snow recedes, targeting lighter fuels including grass and brush within the unit and heavier fuels along the unit boundary. Completion of this initial stage will allow for safer and more manageable firing operations in future entries that will involve burning timbered areas of the unit that create more active fire behavior.

The Monument Ridge Vegetation and Recreation Management Project, proposed by the Sublette County Collaborative, is multifaceted. It addresses vegetation management within the wildland urban interface, wildlife habitat enhancement activities, along with safety and access improvements for recreation. These activities are set to improve forest health and promote wildlife populations for elk, mule deer, and sage grouse. This project will provide positive wildlife benefits and recreation opportunities well into the future.

Little Hornet, windrow, is a prescribed burn, in unit 7, consisting of 52 acres of slash which has been piled into large piles.  Prescribed burning is planned for fall implementations.

Grand Teton National Park is planning prescribed fire operations for 105 acres 
in mid to late May on a portion of the Slough South unit of the Hayfields Restoration Management Area (HMRA). The unit is located east of Blacktail Butte and west of Mormon Row, between the Gros Ventre and Antelope Flats roads.

Prescribed fire is a key component of a multi-stage effort to restore abandoned pastureland in Grand Teton National Park to native vegetation. In collaboration with park vegetation ecologists, this project utilizes prescribed fire, herbicide applications, and other treatments to transition non-native grasses back to native rangeland species across 18 small units.

Since the early 1900s, agricultural activities and livestock grazing significantly impacted the area. Jackson Hole’s early homesteaders converted large tracts of the local sagebrush grasslands to pasture and hay field grasses for agricultural use. These irrigated crops eventually became known as the Kelly Hayfields.

The primary vegetation in the HMRA now consists of invasive agronomic grasses and noxious weeds, including non-native smooth brome and thistle. The restoration process of removing formerly cultivated and other non-native plant species and replacing them with native grasses and shrubs will benefit bison, elk, pronghorn, sage grouse, songbirds, and other native wildlife.   

This multi-unit project area covering approximately 74,267 acres is a result of the Hams Fork decision which includes timber sales, aspen restoration, hazard tree removal and prescribed burning.  Units 6 and 8 approximately total 200 acres and are located within the Hams Fork Vegetation Project and are target to be prescribe burned spring of 2025.
