Name: Salix orestera / Allium validum Shrubland
Reference: Western Ecology Working Group of...
Description: This shrubland association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. This vegetation grows on low-gradient basin floors, streamsides, and wet meadows around 3200 m (10,500 feet) of elevation. Soils are seasonally saturated clay loams. This vegetation forms a dense shrub canopy between 1-2 m in height dominated by <i>Salix orestera</i>. <i>Ribes montigenum</i> is the only other shrub which contributes any appreciable cover. The diagnostic forb is <i>Allium validum</i> which contributes 2.5% cover, as does <i>Potentilla gracilis</i>. The herbaceous layer has several other forbs and graminoids which contribute only trace cover. These may include <i>Achillea millefolium, Cirsium</i> sp., <i>Mimulus primuloides, Montia chamissoi, Muhlenbergia filiformis, Oreostemma alpigenum var. alpigenum, Penstemon rydbergii, Phleum alpinum, Carex fissuricola, Carex spectabilis</i>, and/or <i>Trisetum spicatum</i>.
