CEGL000589 Populus tremuloides / Juniperus communis / Lupinus argenteus Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Quaking Aspen / Common Juniper / Silvery Lupine Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This deciduous forest association is known from plateaus and mountain slopes on Fishland Plateau on the Colorado Plateau, and the southern and central Rocky Mountains from western Colorado and northern Utah to the Wind River Mountains in Wyoming. Elevations range from 2400-2745 m (8000-9000 feet). Stands occur on gentle slopes (<10%) on ridgetops and mesas often on northerly to southeasterly aspects. Substrates are variable and do not seem to restrict this type. Litter covers much of the ground surface. The vegetation is characterized by a moderately dense to dense tree canopy dominated by Populus tremuloides and a low-shrub layer (>10% cover) with Juniperus communis dominant or at least prominent. Several other shrubs, such as Arctostaphylos uva-ursi, Artemisia tridentata, Mahonia repens, Paxistima myrsinites, Symphoricarpos oreophilus, or Symphoricarpos rotundifolius, may be present in the low-shrub layer. Scattered conifers may be present in the tree canopy. Occasional tall shrubs Amelanchier alnifolia and conifer seedlings may also be present but do not form a tall-shrub layer. The moderate herbaceous layer is mostly forbs and is characteristically dominated by Lupinus argenteus with the absence or low cover of Carex geyeri and Calamagrostis rubescens. Other common forb species frequently include Achillea millefolium, Antennaria microphylla, Arnica cordifolia, Astragalus miser, Geranium viscosissimum, Thalictrum fendleri, and the introduced Taraxacum officinale.

Floristics: The association is characterized by a moderately dense to dense tree canopy dominated by Populus tremuloides and a low-shrub layer (>10% cover) with Juniperus communis dominant or at least prominent (Mueggler 1988). Several other shrubs, such as Arctostaphylos uva-ursi, Artemisia tridentata, Mahonia repens, Paxistima myrsinites, Symphoricarpos oreophilus, or Symphoricarpos rotundifolius, may be present in the low-shrub layer. Scattered conifers (Picea pungens, Pseudotsuga menziesii, Pinus contorta, and less often Pinus flexilis or Pinus ponderosa) may be present in the tree canopy. Occasional tall shrubs Amelanchier alnifolia and conifer seedlings may also be present but do not form a tall-shrub layer. The moderate herbaceous layer is mostly forbs and is characteristically dominated by Lupinus argenteus with the absence or low cover of Carex geyeri and Calamagrostis rubescens (Mueggler 1988). Other common forb species frequently include Achillea millefolium, Antennaria microphylla, Arnica cordifolia, Astragalus miser, Geranium viscosissimum, Thalictrum fendleri, and the introduced Taraxacum officinale. Other graminoids present include Achnatherum lettermanii, Achnatherum occidentale, Bromus porteri, Elymus trachycaulus, Festuca arizonica, Poa fendleriana, and the introduced perennial graminoid Poa pratensis.

Environmental Description: This deciduous forest association is known from plateaus and mountain slopes on Fishland Plateau on the Colorado Plateau, and the southern and central Rocky Mountains from western Colorado and northern Utah to the Wind River Mountains in Wyoming. Elevations range from 2400-2745 m (8000-9000 feet). Stands occur on gentle slopes (<10%) on ridgetops and mesas often on northerly to southeasterly aspects (Mueggler 1988). Substrates are variable and do not seem to restrict this type; they include silty and sandy loams derived from volcanics. Litter covers much of the ground surface.
