Name: Abies lasiocarpa - Picea engelmannii / Symphoricarpos albus Forest Reference: Western Ecology Working Group of... Description: This forest association has been found locally from mountains in eastern Idaho, western Wyoming and western Montana. Elevation ranges from 1737-2316 m (5700-7600 feet) . Stands are found on benches, lower slopes and dry alluvial terraces on rocky substrates derived from sandstone and less commonly limestone or andesite parent materials. This forest type has a moderately dense to dense canopy (>60% cover) of evergreen needle-leaved trees over 30 m tall. <i>Abies lasiocarpa</i> dominates or codominates the tree canopy, with <i>Pseudotsuga menziesii</i> or <i>Pinus contorta</i> in seral stands, and occasional <i>Picea engelmannii</i>. <i>Populus tremuloides</i> may also be present in the tree canopy. <i>Amelanchier alnifolia</i> forms a sparse, tall-shrub layer in some stands. The diagnostic understory vegetation is composed of a sparse short-shrub layer dominated by <i>Symphoricarpos albus</i> with lesser amounts of <i>Spiraea betulifolia</i> and <i>Mahonia repens</i>. The graminoid <i>Calamagrostis rubescens</i> dominates the typically sparse herbaceous layer. Other common herbaceous species include <i>Arnica cordifolia, Geranium viscosissimum</i>, and <i>Carex geyeri</i>.  Accession Code: VB.CC.32060.CEGL000337 Plot-observations of this Community Concept: 0
