Name: A.1084
Reference: EcoArt 2002
Description: Stands included in this alliance occur in alpine areas in the Washington Cascade Mountains. Elevations range from 1920-2135 m. This vegetation is found on depressions to gentle slopes with any aspect. Sites are moist areas that receive moisture from surrounding higher ground from melting snowdrifts or small streams. Some stands were found on the base of a lobe of soil formed by solifluction. Soils are poorly drained and derived from thick accumulations of pumice parent material. Mean bare ground was about 13%. Stands typically have a dense evergreen dwarf-shrub layer that is dominated by ~Phyllodoce glanduliflora$. The herbaceous layer is moderately dense to dense, and is codominated by the perennial forbs ~Oreostemma alpigenum (= Aster alpigenus), Lupinus sellulus var. lobbii$, and the perennial graminoid ~Carex spectabilis$. Other consistent species include ~Cassiope mertensiana, Potentilla flabellifolia$, and ~Antennaria lanata$. This is a relatively species-poor community.
