Name: Geum rossii Herbaceous Alliance Reference: Western Ecology Working Group of... Description: This alliance occurs in the alpine tundra throughout the Rocky Mountains. In winter, strong westerly winds deposit snow on the leeward side of the mountains, resulting in areas of deep snow that melt relatively late in the summer. Stands are found in these snowbed habitats on frost-patterned ground, and in depressions where fine soil particles concentrate. Sites occur on all aspects of gentle to moderate-gradient slopes. The soils are wet, poorly developed, and may have a high organic matter content. Vegetation included in this alliance is characterized by the perennial forb Geum rossii dominating the herbaceous layer. Common associates include Polygonum bistortoides, Trifolium parryi, Trifolium nanum, Artemisia scopulorum, Erigeron simplex, Potentilla diversifolia, Deschampsia caespitosa, and Festuca brachyphylla. The moss layer is sparse due to the dense herbaceous cover and Geum rossii litter that covers the ground. Diagnostic of this alpine alliance is the dominance of Geum rossii in the herbaceous layer.  Accession Code: VB.CC.18907.GEUMROSSIIHERBA Plot-observations of this Community Concept: 0
