Name: Abies grandis / Calamagrostis rubescens Woodland
Reference: NatureServe Biotics 2019
Description: This association is described from Washington but is also reported from Idaho, Oregon and Montana. The woodland or forest canopy is typically codominated by <i>Abies grandis</i> and <i>Pseudotsuga menziesii</i> with <i>Pinus ponderosa</i> present to prominent. <i>Abies grandis</i> always occupies over 10% total cover and usually dominates tree regeneration. A sparse, medium-sized shrub layer may be present and is usually comprised of <i>Rosa gymnocarpa, Spiraea betulifolia</i>, or <i>Paxistima myrsinites</i>. The herb layer is well-developed and is dominated by <i>Calamagrostis rubescens</i> and often <i>Carex geyeri</i>. <i>Arnica cordifolia</i> or <i>Moehringia macrophylla</i> may be present. This association is found at middle elevations on all aspects on flat to moderately steep slopes on deep, well-drained colluvial soils. This association occurs in the east Cascades and the northern Rocky Mountains in a relative narrow ecological range. Fire suppression may have increased its local abundance and most of those stands are threatened by wildfire.
