Description: This alliance occurs at middle elevations (1800-2500 m) of mountains in the Intermountain West. These shrublands occur on all aspects of mesic sites, but are generally best developed on north-facing slopes in xeric areas. Soils are variable, from shallow and skeletal near rock outcroppings, to moderately deep with abundant organic matter. These shrublands are typically dense and tall with multiple vegetation layers. The upper shrub layer is dominated by ~Amelanchier utahensis$, often with ~Quercus gambelii$ and ~Prunus virginiana$ as tall-shrub associates. Other shrubs, such as ~Symphoricarpos oreophilus, Purshia tridentata, Chrysothamnus viscidiflorus, Artemisia tridentata, Rosa woodsii$, or ~Cercocarpus montanus$, often form a second, lower shrub layer. The herbaceous layer is typically species-rich and well-developed. Common herbaceous associates include ~Elymus glaucus, Balsamorhiza sagittata, Achnatherum nelsonii ssp. dorei (= Stipa columbiana), Lathyrus pauciflorus, Carex geyeri$, and ~Collinsia parviflora$. Adjacent communities are typically ~Quercus gambelii$ shrublands, ~Pinus ponderosa$ forests, ~Pinus edulis - Juniperus osteosperma$ woodlands, or ~Artemisia$ shrublands.
