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 on February 28. 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 will burn near the base of Carr Canyon in the Huachuca Mountains. The area will be ignited by firefighters from local, state and federal agencies and will be monitored until the fire is completely out. 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 Prescribed Fire Goals:
- 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 dessert 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:
- Continually evaluate and maintain firefighter and public safety.
- Maintain fire within the boundaries of the Carr Barn Prescribed Fire Planning Area.
- Consume over 60% of the one-hour fuels.
- Decrease density of herbaceous and woody cover in the burn area.
- Increase average canopy base height of the stand.
A combination of low to moderate fire behavior will be used to meet the prescribed fire and resource objectives for the project. Lower intensity fire (blacklining) can 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 can be utilized on the interior of the unit to accomplish the resource and prescribed fire 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 in appropriate locations along the Highway 92. 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 Division of Forestry and Fire Management, Douglas and Nogales ranger districts.
