Dynamics: Historically, fires probably occurred about every 10 to 20 years in oak woodlands adjacent to semi-desert grasslands. Intense fires, as a disturbance factor, favor oak species. Small Quercus arizonica are top-killed by fire. Larger trees usually survive low-intensity fires. Its foliage is highly flammable. Fires move quickly through oak woodlands that have a continuous grass understory. Surviving stumps sprout vigorously. Acorns not buried in the soil probably do not survive even low-intensity fire.
Environmental Description: This association is known from a wide variety of landforms, parent materials, and soils; at elevations from 1540 to 2130 m (5000-7000 feet).
Geographic Range: This association occurs in southern New Mexico and Arizona, being more common south of the Mogollon Rim in Arizona.
