Dynamics: Fires occur in this type with moderate frequency and are generally surface fires. Crowning is more likely if fuel ladders from dense pine regeneration or oak thickets exist. Swetnam and Dieterich (1985) found presettlement fire frequencies in the Gila Wilderness ranged from 1 to 22 years with mean fire intervals from 4 to 8 years.
Environmental Description: This woodland occurs on south-facing slopes at elevations of 2040 to 2680 m (6700-8800 feet) to 2879 m (9400 feet). Mean annual precipitation is 58-64 cm (23-25 inches) per year. It is found on many slopes and aspects.
Geographic Range: This ponderosa pine woodland occurs in southwestern and central New Mexico and southern to central Arizona (up to the San Francisco Peaks area).
