Name: Abies lasiocarpa / 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. 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. Abies lasiocarpa dominates or codominates the tree canopy with Pseudotsuga menziesii or Pinus contorta in seral stands, and occasional Picea engelmannii. Populus tremuloides may also be present in the tree canopy. Amelanchier alnifolia forms a sparse, tall-shrub layer in some stands. The diagnostic understory vegetation is composed of a sparse short-shrub layer dominated by Symphoricarpos albus with lesser amounts of Spiraea betulifolia and Mahonia repens. The graminoid Calamagrostis rubescens dominates the typically sparse herbaceous layer. Other common herbaceous species include Arnica cordifolia, Geranium viscosissimum, and Carex geyeri.
