Amelanchier utahensis - Cercocarpus montanus - Cercocarpus intricatus Shrubland Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance is known from the southern Rocky Mountains, Wyoming Basins, Colorado Plateau and extending west to the Great Basin. Stands are characterized by mixed tall-shrub canopies dominated by <i>Amelanchier utahensis, Cercocarpus montanus</i>, or <i>Cercocarpus intricatus</i>. Species that may codominate in some stands include <i>Artemisia tridentata, Fendlera rupicola, Glossopetalon spinescens</i>, and <i>Rhus trilobata</i>. Total canopy cover ranges from sparse to moderately dense. Occasional trees, such as <i>Juniperus</i> spp., <i>Quercus</i> spp., <i>Pinus edulis, Pinus ponderosa</i>, or <i>Pseudotsuga menziesii</i>, may be scattered in some stands. The herbaceous layer is variable and may have sparse to moderate cover. The most typical dominants are graminoids and may include <i>Carex geyeri, Elymus lanceolatus ssp. lanceolatus, Hesperostipa comata</i>, and <i>Pseudoroegneria spicata</i>. Elevations range from 1800-2700 m. Sites are variable but are generally xeric and rocky with moderate to very steep slopes or on ridges. 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.
