Name: Pseudotsuga menziesii / Calamagrostis rubescens Woodland Reference: Western Ecology Working Group of... Description: This lower to mid montane woodland association occurs in the central and northern Rocky Mountains from western Montana to northeastern Washington and British Columbia, and south to western Wyoming, Idaho and eastern Oregon. Elevations range from 825 to 2400 m (2700-7900 feet). Stands occur on cool, dry sites on mid to upper slopes and benches on all aspects at middle elevations. At lowest elevations stands are restricted to north aspects, and at upper elevations stands are found on warm and dry southerly exposures. Substrates are variable (sandy to clayey), but are generally well-drained, coarser-textured gravelly soils and derived from a variety of noncalcareous, acidic parent materials. Surface rock usually is low to moderate, and litter cover high. The typically open tree canopy is dominated by <i>Pseudotsuga menziesii</i> alone or codominated by <i>Pinus ponderosa</i> or <i>Larix occidentalis</i>. Large <i>Pinus albicaulis</i> or <i>Pinus contorta</i> trees may be present in the upper tree canopy. The subcanopy is <i>Pseudotsuga menziesii</i>. Scattered shrubs such as <i>Amelanchier alnifolia, Paxistima myrsinites, Sorbus scopulina</i>, and <i>Symphoricarpos oreophilus</i> and dwarf-shrubs such as <i>Arctostaphylos uva-ursi</i> and <i>Mahonia repens</i> may also be present. The dense to moderately dense (20-60% cover) perennial graminoid layer characteristically dominates the understory. <i>Calamagrostis rubescens</i> typically is the dominant, with <i>Carex geyeri, Festuca idahoensis</i>, and <i>Pseudoroegneria spicata</i> often present to codominant. There is often a high diversity of forbs, but typically all have low cover. Forb species present are highly variable, but the most common forbs species are <i>Achillea millefolium, Antennaria</i> spp., <i>Arnica cordifolia, Balsamorhiza sagittata, Eurybia conspicua, Fragaria virginiana, Geranium viscosissimum</i>, and <i>Geum triflorum</i>.  Accession Code: VB.CC.31131.CEGL000429 Plot-observations of this Community Concept: 0
