Name: A.1294
Reference: EcoArt 2002
Description: This short grassland of dry subalpine and alpine meadows occurs on slopes and ridges from 1500-3700 m elevation. Optimal habitats have subsurface moisture. The precipitation regime where this alliance occurs is strongly seasonal, with most precipitation falling in the winter months. Most precipitation in the upper elevational range falls as snow. Summers are very dry. This alliance is dominated by ~Carex filifolia$ in the herbaceous layer. Other herbs may include ~Oreostemma alpigenum (= Aster alpigenus), Penstemon heterodoxus, Juncus mertensianus, Potentilla$ spp., ~Cistanthe umbellata var. umbellata, Saxifraga aprica, Calamagrostis breweri, Ptilagrostis kingii, Trisetum spicatum, Erigeron algidus, Deschampsia caespitosa$, and ~Achillea millefolium var. occidentalis$. Emergent shrubs like ~Eriogonum nudum$ may be present. This alliance forms large stands and often intergrades with other meadow, forest, and woodland alliances.
