Description: Vegetation types within this short alpine or subalpine sod grassland alliance occur on open, dry, wind-swept slopes at high elevations in the Rocky Mountains. Sites occupy gentle to moderately (3-26%) sloping upland terrain of southerly to easterly exposures at elevations ranging from 2400-4200 m. Stands are found on granitic or metaphormic colluvium. Soils are skeletal and loamy. Coarse fragments are abundant and pH varies from 5.4-6.6. They are found on well-drained sites which receive little or no snow cover. Stands on Trail Ridge, Colorado, are free of snow and frost very early; plants were observed blooming in mid-May. Most moisture is received from summer rains. Carex elynoides dominates the graminoid layer with at least 60% cover, forming an extensive turf. Kobresia myosuroides commonly occurs with Carex elynoides in the graminoid stratum. Typically the forb layer is conspicuous with at least 20% cover. Forb species include Geum rossii, Trifolium dasyphyllum, Arenaria fendleri, Oreoxis alpina (Oreoxis bakeri in New Mexico stands), Potentilla diversifolia, and Phlox caespitosa. Selaginella densa is commonly found in the fern layer.
