Name: Carex scirpoidea Herbaceous Alliance Reference: Western Ecology Working Group of... Description: This is an alpine herbaceous alliance found in the alpine tundra in mountain ranges of southwestern Montana. The alliance occurs between 2800 and 3140 m elevation on all aspects of gentle- to moderate-gradient, wind-swept slopes, often on frost-patterned ground, on solifluction lobes and sorted rock polygons and circles. Soils are derived from sedimentary, metamorphic, and igneous rock types. Some soils, however, are derived from calcareous limestone and conglomerates. Soil texture varies from fine clay to sandy loam. The vegetation is characterized by a dense cover of graminoids, mainly Carex species, and forbs. Carex scirpoidea is the dominant sedge, with Carex phaeocephala and Carex albonigra as common associates. Common forb species include Potentilla diversifolia, Phlox pulvinata, Lupinus argenteus, and Erigeron simplex. Some stands have an abundant cover of Geum rossii. Carex scirpoidea stands grade into alpine grasslands at lower elevations and into Carex elynoides and cushion plant communities on higher slopes with increased wind exposure.  Accession Code: VB.CC.20857.CAREXSCIRPOIDEA Plot-observations of this Community Concept: 0
