Name: Festuca thurberi - Danthonia intermedia - Poa lettermanii Southern Rocky Mountain Subalpine Grassland Alliance
Reference: NatureServe Biotics 2019
Description: Vegetation of this subalpine grassland alliance is characterized by an open to dense perennial graminoid layer composed of bunchgrasses, especially <i>Festuca thurberi</i> and <i>Danthonia intermedia</i>. Other diagnostic and sometimes dominant species include <i>Achnatherum richardsonii, Danthonia parryi, Festuca idahoensis, Geranium viscosissimum, Lathyrus lanszwertii var. leucanthus, Poa lettermanii, Poa nervosa, Potentilla hippiana, Solidago multiradiata</i>, and <i>Sporobolus heterolepis</i>. This alliance occurs largely in the southern Rocky Mountains extending west to the high mountains and plateaus of Arizona, Utah and Nevada. Stands primarily occur in the subalpine and lower alpine slopes in dry meadows and on ridges above subalpine forests in the southern Rocky Mountains, but may extend up into lower alpine and down into montane zones. Elevations range from 2500-3810 m. Climate is temperate with short growing seasons and heavy snowfall in winter. Stands are found on level valley bottoms, expansive park meadow openings in the subalpine forest, and on ridges above subalpine forests. Sites are nearly level to steeply sloping, typically on southern or western exposures. Soils are generally deep, well-drained loams or silt loams with pH of 5.8-7.0, and derived from alluvium and colluvium.
