Name: Amelanchier alnifolia / (Mixed Grass, Forb) Shrubland Reference: Western Ecology Working Group of... Description: This association is currently known only from Glacier National Park and Waterton Lakes National Park. It is found on moderate to steep slopes and flat benches. They are located at moderate elevations between 1300 and 1781 m (4262-5840 feet) predominately on southerly to easterly aspects. Soils tend to be moderately to well-drained sandy or clay loams or, occasionally, a rapidly drained Orthic Regosol. Sites are usually situated on glacial-fluvial or till deposits. Most of the ground surface is covered with litter and duff. This mixed-age shrubland is characterized by the presence of Amelanchier alnifolia, which occurs in all shrub canopy layers with 100% constancy and an average cover of 32%. Other shrubs include Symphoricarpos albus, Holodiscus discolor, Acer glabrum, Rubus parviflorus, and Spiraea betulifolia, with 10% average cover. Shrub height is variable due to heavy browsing or periodic avalanche disturbance, or both. The moderate to dense (70% average cover) herbaceous layer is diverse with over 100 species recorded in 23 stands. Common forb species include Fragaria virginiana, Achillea millefolium, and Galium boreale. Graminoids consist primarily of Carex geyeri and Calamagrostis rubescens; each has moderate constancy and an average cover of 14% and 24%, respectively. Other grasses present include both native and exotic species, such as Festuca idahoensis, Bromus carinatus, Poa pratensis, and Phleum pratense. All have 50% constancy or higher. Nonvascular cover is insignificant.  Accession Code: VB.CC.28138.AMELANCHIERALNI Plot-observations of this Community Concept: 0
