Name: Carex elynoides - Geum rossii Alpine Turf Reference: NatureServe Biotics 2019 Description: This Rocky Mountain association is found in exposed, upland subalpine and alpine environments. Sites are typically dry meadow and alpine turf at middle to lower alpine and around treeline but may occur on moist fell-fields. Stands often occur near the top of convex slopes that are moderate to somewhat steep. Aspects are variable, but sites tend to be exposed to winter wind that limits depth of snowpack. Soils are moderately well-drained to well-drained loams or sandy loams. Soils are relatively well-developed for the alpine with several centimeters of organic material usually present. There is significant cover of large and small surface rocks and bare ground, especially in transition areas with fellfields. Vegetation is characterized by a moderately dense to dense (&gt;50% cover) herbaceous layer dominated by <i>Carex elynoides</i>, occurring at 30-70% cover. Codominants are typically <i>Geum rossii</i> but may also include significant cover of <i>Carex nardina, Festuca brachyphylla, Castilleja occidentalis, Selaginella densa</i>, and <i>Trifolium nanum</i>. Cover of cushion plants is typically low except in fellfield transition areas or disturbed sites. Low dwarf-shrub cover (&lt;5%) of <i>Artemisia arctica ssp. arctica</i> and <i>Salix planifolia</i> may be present.  Accession Code: urn:lsid:vegbank.org:commConcept:30762-{B8789818-C498-4FD5-B1C6-31E269346A64} Plot-observations of this Community Concept: 0
