Name: Cercocarpus montanus - Quercus x pauciloba Shrubland Alliance
Reference: NatureServe Biotics 2019
Description: The vegetation of this alliance is characterized by shrublands most commonly dominated by <i>Cercocarpus montanus</i>, but in the southern portion of its range is codominated by <i>Quercus x pauciloba</i>. Structure varies from dense to having little to no canopy overlap with lush herbaceous layers. Shrub associates may include <i>Ceanothus greggii, Dasylirion leiophyllum, Quercus grisea</i> (shrub form), and <i>Quercus turbinella</i>. The understory is most commonly graminoid-dominated by <i>Bouteloua curtipendula, Hesperostipa neomexicana, Muhlenbergia montana</i>, or <i>Petrophytum caespitosum</i>. Additional species may include <i>Achnatherum scribneri, Bouteloua gracilis, Carex geyeri, Elymus albicans, Festuca arizonica</i>, and the perennial forbs <i>Helianthus pumilus, Heterotheca villosa, Potentilla fissa</i>, and <i>Scutellaria brittonii</i>. Introduced annual grass <i>Bromus tectorum</i> is often present. This alliance primarily occurs in the southern Rocky Mountains, northern Chihuahuan Desert and east to the Southern Shortgrass Prairie, but has outlying occurrences in adjacent ecoregions. It occurs on montane slopes at 915 to 2440 m (3000-8000 feet) elevation. Stands are found on various aspects, but typically the higher elevation and northern sites are on warmer, southern exposures, and lower elevation and southern stands are restricted to more mesic north slopes.
