Name: Populus tremuloides / Amelanchier alnifolia - Symphoricarpos oreophilus / Mixed Graminoid Forest Reference: Western Ecology Working Group of... Description: This aspen forest is found in northwestern Colorado and southwestern Wyoming on moderate to moderately steep slopes (10-30%) of mountains, plateaus and buttes between 2242 and 2724 m elevation. It occurs in small stands on toeslopes, slump slopes, benches, and ridges often with north aspects or in other areas that collect snow or have a higher soil moisture throughout the growing season (seeps). The unvegetated surface generally has low cover of small and large rocks and high cover of leaf litter and downed wood, although in some stands the cover by large rocks may be as high as 40%. Soils are well-drained to poorly drained with soil textures ranging from sandy loam to silt to clay loam. The vegetation is characterized by an open to dense tree canopy 2-10 m tall that is dominated by <i>Populus tremuloides</i> with open to dense shrub layers dominated by tall shrubs <i>Amelanchier alnifolia</i> or <i>Amelanchier utahensis</i> and short shrub <i>Symphoricarpos oreophilus</i>. Scattered <i>Pseudotsuga menziesii</i> or <i>Pinus flexilis</i> may be present in some stands. Other tall shrubs may include <i>Salix scouleriana</i> and <i>Prunus virginiana</i>. Short- and dwarf-shrub associates, such as <i>Artemisia tridentata ssp. tridentata, Artemisia tridentata ssp. vaseyana, Juniperus communis, Mahonia repens, Paxistima myrsinites, Rosa woodsii, Shepherdia canadensis</i>, and <i>Ribes cereum</i>, may be present with low cover. The herbaceous layer is characterized by mixed graminoids, such as <i>Achnatherum lettermanii, Hesperostipa comata, Bromus</i> sp., <i>Carex geyeri</i>, and <i>Poa secunda</i>, and low cover of diverse forbs. Exotic species <i>Poa pratensis</i> and <i>Taraxacum officinale</i> are common in some stands.  Accession Code: VB.CC.31932.CEGL002816 Plot-observations of this Community Concept: 0
