Name: Picea engelmannii / Juniperus communis Forest Reference: Western Ecology Working Group of... Description: This late-seral subalpine conifer association is found in the mountains of northwestern Wyoming, eastern Idaho and northwestern or north-central Montana. Elevation ranges from 2000 to 3140 m. Stands usually occur on cooler northern and eastern aspects on a variety of terrain on dry, rocky substrates derived from calcareous, volcanic, or granitic parent materials. In Montana, stands occurred on steep, south-facing talus slopes, with rocky, poorly developed soils. Otherwise, the soil surface typically has high cover of litter with low cover of bare soil and rock. This association has an open to moderately dense to dense (30% to over 60%) canopy of conifer trees over 30 m tall that is dominated by Picea engelmannii or Picea engelmannii X glauca hybrids. Other trees in the canopy may include Pseudotsuga menziesii, Pinus flexilis, or Pinus contorta depending on substrate. Pinus albicaulis is sometimes present in the northerly stands in Montana. Abies lasiocarpa is absent from the tree canopy and regeneration layer. The understory is composed of large, dense, short-shrub patches of Juniperus communis with Shepherdia canadensis common in seral stands. The sparse herbaceous layer is composed of the forbs Arnica cordifolia, Astragalus miser, Solidago multiradiata, Chamerion angustifolium (= Epilobium angustifolium), Frasera speciosa, and the graminoids Carex rossii and Poa nervosa.  Accession Code: VB.CC.28084.PICEAENGELMANNI Plot-observations of this Community Concept: 0
