Name: A.1315
Reference: EcoArt 2002
Description: This alliance occurs in subalpine and lower alpine meadows in the mountains and plateaus of Colorado, Utah and Washington. Stands are found on a variety of somewhat mesic sites: gentle to steep slopes, benches, dry to wet meadows, and along streams. Soils are shallow and well-drained. Vegetation in this alliance is characterized by a moderately sparse to moderately dense herbaceous layer that is dominated by ~Danthonia intermedia$. Total vegetation cover is controlled by the amount of rock cover. Associated graminoids include ~Agrostis variabilis, Carex engelmannii, Carex microptera, Carex scirpoidea, Festuca brachyphylla, Juncus drummondii, Trisetum spicatum$, and ~Poa$ spp. Forb cover codominates the herbaceous layer, with species such as ~Achillea millefolium, Symphyotrichum foliaceum (= Aster foliaceus), Erigeron simplex, Erigeron ursinus$, or ~Solidago multiradiata$ often abundant. The ground surface is often covered with nonvascular plants that form a cryptogamic crust. Diagnostic of the herbaceous alliance is the dominance of the bunchgrass ~Danthonia intermedia$.
