CEGL000466 Pseudotsuga menziesii / Vaccinium membranaceum Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Douglas-fir / Thinleaf Huckleberry Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: 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 Pseudotsuga menziesii. Other conifers often present in the subcanopy include Pinus contorta, Abies lasiocarpa, Picea engelmannii, Abies grandis, Pinus albicaulis, Pinus ponderosa, and Larix occidentalis. Pinus contorta is the most common co-associate. The understory is relatively open; the short- (1-3 feet tall ) and dwarf-shrub layers (<1/2 foot tall) are dominated by Vaccinium membranaceum. Other shrubs that may be present include Spiraea betulifolia, Lonicera utahensis, Paxistima myrsinites, Sorbus scopulina, Acer glabrum, and Mahonia repens. In the northern part of the range, stands may lack Vaccinium membranaceum but have another indicator species, Xerophyllum tenax, and few other shrubs present. Calamagrostis rubescens is the most common graminoid in the herbaceous undergrowth.
