Dynamics: Historically, fires probably occurred about every 10 to 20 years in oak woodlands adjacent to semi-desert grasslands. 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 occurs on canyon and piedmont hillslopes of highly variable parent materials and soils at elevations from 1460 to 1890 m (4800-6200 feet).
Geographic Range: This association is found in the Animas, Peloncillo, and Burro mountains of southwestern New Mexico and adjoining southeastern Arizona; being extensive south of the Mogollon Rim in Arizona, and very local elsewhere.
