Name: Salix arctica - Vaccinium caespitosum / Calamagrostis breweri - Antennaria media Dwarf-shrubland
Reference: Western Ecology Working Group of...
Description: This dwarf-shrubland association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands of this association are found near seeps, streams, or lakes between 3050 and 3415 m (10,000-11,200 feet) of elevation. Soils are seasonally saturated silt loams and clay loams derived from igneous and metamorphic parent materials. Slopes are gentle to moderate, and stands prefer basins as well as lower and sometimes middle slope positions. Aspects are generally north and east. This vegetation forms a low, intermittent canopy less than 0.5 m in height. Graminoids tend to be emergent over the low, mat-forming dominant shrub species <i>Salix arctica</i>. <i>Vaccinium caespitosum</i> and <i>Kalmia polifolia</i> complete the subshrub "canopy." Forbs provide a little cover, primarily <i>Antennaria media, Castilleja lemmonii, Oreostemma alpigenum var. alpigenum, Luzula congesta, Potentilla drummondii</i>, and/or <i>Gentiana newberryi</i>. Many graminoid species are present, mostly <i>Carex</i> and <i>Juncus</i> species. The most common graminoids are <i>Trisetum spicatum</i>, the diagnostic graminoid <i>Calamagrostis breweri</i>, and/or <i>Juncus parryi</i>.
