Name: Carex pyrenaica Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This association is found in alpine areas of late-melting snowpatches that are located on lee sides of saddles, hills and knolls, and rock outcrops in the alpine zone of Colorado. Stands occur on sites where heavy snow accumulates during the winter, typically on eastern to southeastern slopes. Sites are cool and moist from late-melting snow. Rock and bare soil may cover up to half the ground surface. Soils are well-drained, poorly developed and rocky. The vegetation is characterized by a relatively open to moderately dense herbaceous layer that is dominated by <i>Carex pyrenaica</i> often with <i>Erigeron melanocephalus</i>. Other important herbaceous species include <i>Antennaria</i> spp., <i>Polygonum bistortoides (= Bistorta bistortoides), Castilleja occidentalis, Carex phaeocephala, Geum rossii, Juncus drummondii, Luzula spicata, Poa arctica, Potentilla</i> spp., and <i>Sibbaldia procumbens</i>. Mosses such as <i>Polytrichum piliferum</i> and <i>Pohlia obtusifolia</i> are often present and may form a moderately dense nonvascular layer.  Accession Code: VB.CC.33754.CEGL001860 Plot-observations of this Community Concept: 0
