Name: Potentilla sierrae-blancae Herbaceous Alliance Reference: Western Ecology Working Group of... Description: This alliance occurs in a mountainous region of southern New Mexico. This alliance is found at high elevations (between 10,500 and 11,800 feet) on open, wind-swept slopes that can be characterized as alpine tundra. The sites are above timberline and typically cold and dry, due to constant winds which maintain snow-free slopes. The soils are thin, lithosolic, extremely cobbly and excessively drained. Most of the species in this alliance are perennial forbs, with the characteristic cushion-plant growth form found in tundra plants, an adaptation to the harsh, windy environment. Potentilla sierrae-blancae is the dominant species. Other common species include Minuartia obtusiloba, Primula rusbyi (= Primula ellisiae), Pseudocymopterus montanus, and Zigadenus elegans. Graminoid species are not abundant. Lichens are very common, but there is no information on what species are present.  Accession Code: VB.CC.25041.POTENTILLASIERR Plot-observations of this Community Concept: 0
