RM-RN-418: Stand, fuel, and potential fire behavior characteristics in an irregular southeastern Arizona ponderosa pine stand


Harrington, Michael G. 1982. Stand, fuel, and potential fire behavior characteristics in an irregular southeastern Arizona ponderosa pine stand. Res. Note RM-RN-418. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Forest and Range Experiment Station. 6 p.

Arizona's natural ponderosa pine stands are characterized by open, mature groups and adjacent closed, dense thickets. The open structure of the mature groups permits a warm, dry environment, resulting in very low fuel moisture during much of the fire season and creating high ignition and fire spread potentials in the abundant fuels. The large woody fuel component of the adjacent closed groups contributes to a high crown fire potential in the low, dense sapling crowns. These findings suggest a need for fuel management activities where values-at-risk are high.

Keywords: fuel loadings, stand characteristics, fire behavior potential, Pinus ponderosa var. arizonica
