Name: Empetrum nigrum Alpine Dwarf-shrubland Alliance Reference: NatureServe Biotics 2019 Description: These dwarf-shrub communities are dominated by <i>Empetrum nigrum</i> with a mixture of forbs and graminoids interspersed. <i>Phyllodoce glanduliflora, Salix nivalis</i>, and <i>Vaccinium scoparium</i> may also occur in the shrub layer, but are usually not abundant. <i>Lupinus arcticus ssp. subalpinus</i> and <i>Lupinus sellulus var. lobbii</i> are often characteristic forb species, and <i>Carex spectabilis</i> is the most abundant graminoid species. Other common herbaceous associates include <i>Erigeron aureus, Festuca brachyphylla, Luzula spicata, Oreostemma alpigenum, Pedicularis contorta</i>, and <i>Solidago simplex var. spathulata</i>. Adjacent vegetation is usually <i>Tsuga mertensiana</i>- or <i>Abies lasiocarpa</i>-dominated parklands, dry montane grasslands, wet sedge meadows, or rock and ice on higher elevation alpine slopes. Plant associations in this alliance are typically located just above treeline in the Cascade Range of the Pacific Northwest and form distinctive fell-field communities above treeline. The climate is cold with deep snow accumulations, a short growing season, and annual precipitation exceeding 150 (500) cm. Elevations typically range from 1700-2400 m. This alliance occurs on well-drained, moderately steep slopes. Aspects are typically southern or western in the northern Cascades, but tend to be northerly on Mount Rainier. Soils are composed of varied parent materials, but are usually young and poorly developed.  Accession Code: urn:lsid:vegbank.org:commConcept:38161-{E2F2E0CD-48A5-4457-80E6-9CA5429914D8} Plot-observations of this Community Concept: 0
