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.
