Name: Picea engelmannii / Linnaea borealis Forest Reference: Western Ecology Working Group of... Description: This forest association has been described from western and south-central Montana and northwestern Wyoming. Sites supporting stands of this association are in the habitat type of the same name, and include steep slopes, gentle northeastern slopes, alluvial terraces, and well-drained benches that shed cold air, in an altitude range of 1890-2500 m (6200-8200 feet). The soils are generally non-calcareous. The vegetation consists of a tree overstory dominated or codominated by <i>Picea engelmannii</i> and often containing the seral species <i>Pinus contorta</i> and <i>Pseudotsuga menziesii</i>. <i>Picea engelmannii</i> and/or the <i>Picea engelmannii x glauca</i> hybrid are the diagnostic tree species in this forest association. The shrub layer often is dominated by <i>Vaccinium membranaceum (= Vaccinium globulare), Vaccinium scoparium, Alnus viridis ssp. sinuata (= Alnus sinuata)</i>, or <i>Symphoricarpos albus</i>. <i>Juniperus communis</i> (typical of dry sites) may also be a common species in southern stands. <i>Linnaea borealis</i> contributes at least 5% of the undergrowth cover and often dominates or codominates the undergrowth. Other common species are <i>Calamagrostis rubescens</i> (which may dominate the undergrowth), <i>Arnica cordifolia, Chamerion angustifolium (= Epilobium angustifolium), Fragaria vesca, Osmorhiza berteroi (= Osmorhiza chilensis)</i>, and <i>Orthilia secunda (= Pyrola secunda)</i>.  Accession Code: VB.CC.33555.CEGL002689 Plot-observations of this Community Concept: 0
