Name: Heuchera bracteata Herbaceous Alliance Reference: Western Ecology Working Group of... 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.  Accession Code: VB.CC.17863.HEUCHERABRACTEA Plot-observations of this Community Concept: 0
