Name: Carex arapahoensis Herbaceous Alliance Reference: Western Ecology Working Group of... Description: Vegetation types within this alliance are infrequent and are found above timberline in the southern Rocky Mountains. Occurrences are on stabilized, small to medium-sized scree habitats in the alpine zone (3000-3900 m). They typically occur on east-oriented, gently sloping (2-20%) sites. The snow cover lasts well into the summer, providing mesic and cool habitats. Soils are skeletal, thin, typically with rock outcrops. Organic matter content is low. Clay content is high with fine-sized particles. Vegetation types within this alliance are classified as short alpine or subalpine dry bunch grasslands. They are dominated by Carex arapahoensis that typically shares dominance with Minuartia biflora. Other graminoids can include Trisetum spicatum and Festuca brachyphylla. The nonvascular stratum is usually present and includes Cladonia pyxidata and Polytrichum piliferum. Information on adjacent communities is not available.  Accession Code: VB.CC.19451.CAREXARAPAHOENS Plot-observations of this Community Concept: 0
