Description: Communities within the ~~Salix arctica$ Saturated Dwarf-shrubland Alliance (A.1124)$$ occur on subalpine meadows or on high mountain peaks in Nevada. They range in elevation from 2800 to over 3500 m. Landforms that support these associations are typically gentle to moderate in slope and have northerly aspects. They occur where snow lingers into the spring and summer in places such as lees of cliffs and boulders, secondary slopes, and shallow depressions. Soils are probably wet throughout the growing season, as ~Caltha leptosepala$ is always associated with wet soils. Communities within this alliance are defined as cold-deciduous dwarf-shrublands. They are dominated by ~Salix arctica$, which forms a thick canopy with a mat-forming growth form seldom rising more than 1 dm above the ground. ~Salix reticulata$ occasionally is found as a codominant in the dwarf-shrub layer. The herbaceous layer commonly includes ~Caltha leptosepala, Erigeron peregrinus, Polygonum bistortoides$, and ~Pedicularis groenlandica$. No other information on species composition is available.
