Name: Abies lasiocarpa - Picea engelmannii / Vaccinium caespitosum / Clintonia uniflora Forest Reference: Western Ecology Working Group of... Description: This forest association occurs in the lower subalpine zone in the northern Rocky Mountains. Sites are cool, relatively moist benches and may be frost pockets. Elevations range from 945-1250 m (3100-4100 feet). Substrates are typically well-drained, gravelly, sandy loam- to silt-textured soils derived from argillite, quartzite or glacial till. Litter dominates ground surface over 3 cm deep with low cover of bare soil and rock. The vegetation of this conifer association is characterized by Abies lasiocarpa and Picea engelmannii codominating the tree canopy with 5% cover or more of Vaccinium caespitosum and/or Arctostaphylos uva-ursi. Clintonia uniflora or Tiarella trifoliata are always present in stands and not confined to mesic microsites. The evergreen needle-leaved tree canopy is open to moderately dense (30-65% cover). The upper tree canopy is typically codominated by Picea engelmannii and mature seral tree species, with Abies lasiocarpa dominating the subcanopy and regeneration layers. Important seral species in the tree canopy are Pseudotsuga menziesii, Larix occidentalis, Pinus ponderosa, and Pinus contorta. Undergrowth is variable; however. an open to dense dwarf-shrub layer is present and is codominated by Arctostaphylos uva-ursi, Linnaea borealis, and Vaccinium caespitosum. The herbaceous layer is often dominated by Xerophyllum tenax or Calamagrostis rubescens.  Accession Code: VB.CC.26050.ABIESLASIOCARPA Plot-observations of this Community Concept: 0
