Reference: EcoArt 2002
Description: Communities within the ~~Salix reticulata$ Dwarf-shrubland Alliance (A.1119)$$ are found on rocky slopes in alpine areas on level to moderately steep, exposed, southern slopes. Elevation ranges from 1950 m to 2400 m. The soils are extremely rocky and often show indications of frost action (i.e., unsorted nets, frost-boils). Snowmelt is relatively early, generally occurring between mid-May and early June. This alliance is a cold-deciduous dwarf-shrubland. The dwarf-shrub layer is dominated by ~Salix reticulata$, a mat-forming, creeping alpine shrub that forms continuous cover (>75%). The herbaceous layer forms a sparse to moderately dense cover (10-25%). Species include ~Festuca brachyphylla, Carex scirpoidea, Oxytropis campestris, Erigeron aureus$, and ~Lupinus lepidus$. Total cover of the shrub and herbaceous layers is often over 75%. ~Selaginella densa$ is a constant associate in stands in the North Cascades, as are a variety of lichens and mosses. Information on adjacent plant communities is unavailable.
