Name: A.1325
Reference: EcoArt 2002
Description: This alliance includes an alpine snowbed community that was described from the Rocky Mountains of southwestern Montana. Elevations range from 2900-3000 m. Stands were common near the base of gentle alpine slopes where deep snow accumulates in the winter. Sites are flat to gently sloping often with southern aspects on the lee slide of knolls or ridges away from the prevailing southwest and west wind. The growing season is short because the deep snow cover often lasts to midsummer resulting in cold wet soils. Soils are shallow, poorly developed clays with the soil surface having high cover of gravel and bare ground (50%). Vegetation in this alliance has a moderately dense herbaceous layer codominated by the perennial graminoid ~Juncus parryi$ and the perennial forb ~Erigeron ursinus$. Common associates include the perennial grasses ~Festuca idahoensis$ and ~Poa glauca$, and the forbs ~Erigeron peregrinus, Erigeron simplex, Antennaria umbrinella$, and ~Lewisia pygmaea$. There is also sparse moss and lichen cover. Adjacent vegetation is typically grasslands dominated by ~Festuca idahoensis$ and ~Potentilla diversifolia$.
