CEGL000916 Abies grandis / Calamagrostis rubescens Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Grand Fir / Pinegrass Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is described from Washington but is also reported from Idaho, Oregon and Montana. The woodland or forest canopy is typically codominated by Abies grandis and Pseudotsuga menziesii with Pinus ponderosa present to prominent. Abies grandis 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 Rosa gymnocarpa, Spiraea betulifolia, or Paxistima myrsinites. The herb layer is well-developed and is dominated by Calamagrostis rubescens and often Carex geyeri. Arnica cordifolia or Moehringia macrophylla 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.
