Name: A.1646
Reference: EcoArt 2002
Description: This alliance occurs in the alpine tundra in the Colorado Front Range. Stands are located primarily in the lower subnival zone, the area just below permanent snow and ice, on granite and gneiss rock outcrops that are nearly blown free of snow in winter. Stands are found on warm, dry microsites in rock crevices and on outcrop ledges. Soils are young and poorly developed, with the majority of the ground surface covered with rock. ~Heuchera bracteata$ and ~Heuchera parvifolia var. nivalis$ are the dominant species. ~Potentilla nivea$ and ~Elymus scribneri$ are common associates. The cryptogam layer is sparse due to the ~Heuchera$ leaf litter that covers the ground. ~Tortula norvegica$ is the most common moss species, and ~Cladonia pyxidata$ and ~Xanthoria elegans$ are the most common lichens present.
