Fire managers on the Sierra Vista Ranger District, Coronado National Forest expect to ignite the Carr Barn West (148 acres) and Carr Barn East (160 acres) prescribed fires in the early morning on April 21, 2017. Ignitions are contingent upon conditions falling within prescriptive parameters such as temperature, wind speed and direction, relative humidity, fuel moisture, and fire behavior.
The 308-acre Carr Barn Prescribed Fire is located at the Carr Barn Administrative Site, on the east side of State Highway 92 near the Sierra Vista Ranger District office. The burn will be ignited by firefighters from local, state and federal agencies and will be monitored until the it has been completed and the fire extinguished. The project is expected to be completed in one day.
Prescribed fires are among the most effective tools available to resource managers to restore fire-adapted ecosystems. They mimic natural fires by reducing forest fuels, recycling nutrients and increasing habitat diversity. Each prescribed fire is designed to meet specific goals and objectives.
Carr Barn Prescribed Fire Goals:
- Continually evaluate and maintain firefighter and public safety.
- Maintain fire within the boundaries of the Carr Barn Prescribed Fire Planning Area.
- Reduce the risk of high-severity wildfire occurring within the project area by reducing fuel accumulations to more natural levels.
- Maintain vegetation in areas to support desired future conditions.
- Reduce risk of unplanned ignitions in the Wildland/Urban Interface to minimize risk to fire personnel and the public.
Carr Barn Prescribed Fire Resource Objectives:
- Encourage the reestablishment of native grasses.
- Reduce desert broom.
- Support U.S. Forest Service stock animals that use the project area to forage. Fire recycles nutrients stored in aging and decadent vegetation back into the soil, improving the quality of forage plants such as grasses and shrubs.
Carr Barn Prescribed Fire Objectives:
- Consume 60 to 100% of the one-hour fuels (grasses).
- Decrease herbaceous density by 20 to 50% in all herbaceous and woody cover.
- Increase average canopy base height by removing the decadent lower canopy of the existing oak trees.
A combination of low to moderate fire behavior will be used to meet the Prescribed Fire Resource and Fire Objectives for the project. Lower intensity fire (blacklining) will be used to secure the boundaries of the unit, providing a solid buffer to hold the fire within the project area and maintain firefighter safety. Greater fire intensities will be utilized on the interior of the unit to accomplish objectives.
Visitors are cautioned to avoid the project area for safety purposes and to allow fire managers to safely and effectively perform their work.
Prescribed Fire signs will be posted along State Highway 92. The northbound lane of State Highway 92 will be closed between the approximate hours of 5:30 to 10:00 a.m. for firefighter safety. Smoke may be visible from outlying areas, including Sierra Vista. Motorists should drive with caution as smoke may impair visibility during daylight or nighttime hours.
Cooperators include Fry Fire Department, Huachuca City Fire Department, Palominas Fire Department, Sonoita Fire Department, Arizona Department of Forestry and Fire Management, Douglas and Nogales ranger districts.
