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.

 The Jackson Ranger District plans to resume prescribed fire operations at Munger Mountain as early as April 8, 2026. These operations are part of a multi-year effort to reduce overgrown vegetation and protect local communities from future wildfires.

Key Details

• Start Date: As early as April 8, 2026, depending on weather and fuel conditions.
• Location: The Munger Mountain unit is located approximately five miles south of Jackson, WY.
• Location: The Munger Mountain unit is located approximately five miles south of Jackson, Wyoming, near Highway 89/191 and Evans Road.
• Project Scope: Fire crews aim to treat portions of the 1,663-acre unit using a "mosaic pattern" to create a diverse landscape.
• Primary Objective: To decrease hazardous fuel loads and improve wildlife habitat for species like elk, moose, and mule deer. 

Public Impact & Safety

• Smoke Visibility: Smoke will likely be visible from the surrounding area, including Highway 89/191 and parts of Jackson Hole.
• Road Safety: Drivers are advised to slow down and use headlights if smoke is present
• Area Access: No formal closures are currently anticipated, but fire personnel may briefly pause traffic for public safety during active burning.

Monitoring: Real-time air quality updates can be found via the AirNow Fire and Smoke Map.

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.

Grand Teton National Park is planning a prescribed fire for 196 acres near Mormon Row, on part of the Hayfields Restoration Management Area near Mormon Row starting April 9, 2026.

Key Details

• Start Date: April 9, 2026
• Location: East of Blacktail Butte and west of Mormon Row, between the Gros Ventre and Antelope Flats roads
• Project Scope: The 196 acre prescribed fire area is part of the larger 4,000 acre Hayfields Restoration Management Area.
• Primary Objective: The burn aims to restore fallow hayfields in Grand Teton National Park to native vegetation. Removing non-native vegetation will also benefit wildlife, such as bison, elk, pronghorn, sage grouse, and songbirds, and will reduce fuels near historic park structures in case of a wildfire.

Public Impact & Safety

• Smoke Visibility: Smoke will be visible on the day of the burn, mostly during the warmest part of the day. With cooler temperatures in the evening, smoke may linger and accumulate in low-lying areas. Visit https://fire.airnow.gov/ to monitor smoke.
• Road Safety: Drivers are asked to slow down and use caution as fire vehicles and personnel may be working near the roadway. 
• Area Access: No area closures are expected but park staff may pause traffic briefly to allow firefighters to safely work along the road, if necessary.

Monitoring: Safety factors, weather conditions, air quality, personnel availability, and environmental regulations are continually monitored as part of any fire management operation.
