RM-RN-402: Preliminary burning prescriptions for ponderosa pine fuel reductions in southeastern Arizona


Harrington, Michael G. 1981. Preliminary burning prescriptions for ponderosa pine fuel reductions in southeastern Arizona. Res. Note RM-RN-402. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Forest and Range Experiment Station. 7 p.

Natural ponderosa pine fuels can be safely burned with air temperatures between 55° and 75° F, relative humidities between 25% and 50%, and windspeeds less than 10 miles per hour. The moisture content of the surface L layer needles should be between 5% and 10%. Total fuel reduction will depend on H layer moisture. Burning under these conditions will lessen the wildfire hazard by reducing fuel loadings, thinning the stand, removing ladder fuels, and raising the canopy level.

Keywords: fuel reduction, hazard reduction, burning prescription, Pinus ponderosa var. arizonica.
