Name: Pseudotsuga menziesii / Vaccinium membranaceum Forest Reference: NatureServe Biotics 2019 Description: This association occurs in the mountains of northern and eastern Idaho, western and central Montana, and western Wyoming. It occurs from 1310 to 2286 m (4300-7500 feet) in elevation on mostly north-facing slopes but can occur on any aspect; slopes are moderately steep to steep (12-82%). Soils are well-drained, generally acidic, with gravelly sandy loam to gravelly silty loam textures. These tall forests are dominated by mature <i>Pseudotsuga menziesii</i>. Other conifers often present in the subcanopy include <i>Pinus contorta, Abies lasiocarpa, Picea engelmannii, Abies grandis, Pinus albicaulis, Pinus ponderosa</i>, and <i>Larix occidentalis</i>. <i>Pinus contorta</i> is the most common co-associate. The understory is relatively open; the short- (1-3 feet tall ) and dwarf-shrub layers (&lt;1/2 foot tall) are dominated by <i>Vaccinium membranaceum</i>. Other shrubs that may be present include <i>Spiraea betulifolia, Lonicera utahensis, Paxistima myrsinites, Sorbus scopulina, Acer glabrum</i>, and <i>Mahonia repens</i>. In the northern part of the range, stands may lack <i>Vaccinium membranaceum</i> but have another indicator species, <i>Xerophyllum tenax</i>, and few other shrubs present. <i>Calamagrostis rubescens</i> is the most common graminoid in the herbaceous undergrowth.  Accession Code: urn:lsid:vegbank.org:commConcept:29375-{BA94DE03-B91C-4732-92D3-BCCA21AFC36E} Plot-observations of this Community Concept: 0
