Name: Amelanchier utahensis / Pseudoroegneria spicata Shrubland
Reference: Western Ecology Working Group of...
Description: This shrubland association occurs on steep colluvial sites between 2400 and 2625 m (7875-8610 feet) elevation on south- and west-facing mountain slopes in Middle Park of north-central Colorado and between 1650 and 1800 m (5410-5900 feet) on north-facing canyon slopes in northwestern Colorado and adjacent Utah. Soils tend to be coarse and gravelly, with a high percentage of surface rock. The vegetation is somewhat heterogeneous but is characterized by a moderate to dense shrub layer that is usually dominated by <i>Amelanchier utahensis</i>, with <i>Symphoricarpos oreophilus</i> and the perennial bunchgrass <i>Pseudoroegneria spicata</i> always present in the herbaceous layer. Other shrubs may include <i>Artemisia tridentata ssp. wyomingensis, Cercocarpus montanus, Ephedra viridis, Holodiscus dumosus, Philadelphus microphyllus, Prunus virginiana, Purshia tridentata, Rhus trilobata</i>, and <i>Ribes cereum</i>. The herbaceous layer is variable among sites but often includes <i>Achnatherum hymenoides (= Oryzopsis hymenoides)</i>. Commonly associated forb species include <i>Astragalus convallarius, Delphinium x occidentale, Delphinium bicolor ssp. bicolor (= Delphinium nuttallianum), Castilleja flava, Linum lewisii, Packera cana (= Senecio canus)</i>, and <i>Mertensia lanceolata</i>.
