Physiognomy and Structure: At El Malpais National Monument in New Mexico, the tree canopies of this woodland association are very open (25-35% cover) and are codominated by Pinus edulis and Juniperus monosperma. Typically Pinus ponderosa is also well-represented in the canopy. The understory of this woodland is characteristically shrubby (up to 15% cover), and is dominated by the diagnostic species Quercus x pauciloba. Opuntia polyacantha, Echinocereus coccineus, Fallugia paradoxa, and Opuntia phaeacantha are all frequent associates in this xeric woodland, though cover is usually low. The herbaceous layer cover is low (up to around 2%) and typically evenly distributed between forbs and graminoids. Xeric woodland species such as Bouteloua gracilis, Bouteloua curtipendula, Schizachyrium scoparium, Heterotheca villosa, Artemisia carruthii, Schoenocrambe linearifolia, and Glandularia bipinnatifida are most commonly represented in the herbaceous layer.

Environmental Description: This association is found in southern (Sacramento Mountains, Lincoln National Forest and Mescalero Apache Reservation), central New Mexico, and locally in northern New Mexico (including northeastern mesas) at 1830 to 2440 m (6000-8000 feet) elevation on moderate to steep mountain slopes, often on lithic skeletal soils. At El Malpais, it occurs between around 2085 and 2130 m (6840-7000 feet) in elevation, typically on gently rolling lava plateaus of the Bandera and McCarty''s flows, on substrates derived from basalt; it also occurs occasionally on the tops of low hills on Dakota sandstone substrates in the northeast part of the monument.
Geographic Range: This woodland association is found in New Mexico and Colorado.
