Name: Phlox covillei - Elymus elymoides - Podistera nevadensis Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This herbaceous 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. Stands of this alpine association occur on talus slopes and ridgelines at about 3380 m (11,100 feet) elevation. Slopes are moderate to steep. Aspects are south and west, and sites are probably free of snow early in the season followed by a long, droughty summer. Soils are well-drained sands with significant talus or cobble. This sparse alpine herbaceous vegetation is characterized by a low (&lt;0.5 m) open canopy of forbs and graminoids. Thirty-eight species have been recorded in plots of this type. <i>Phlox covillei</i> is the dominant forb. <i>Arenaria kingii ssp. compacta</i> is also usually present. <i>Podistera nevadensis</i> is a diagnostic forb, occurring in 75% of stands. <i>Elymus elymoides ssp. californicus</i> is also a constant and the most common graminoid. Other common forb associates may include <i>Eriogonum ovalifolium, Eriogonum rosense, Castilleja nana, Draba densifolia, Ericameria parryi var. monocephala, Astragalus whitneyi var. whitneyi, Astragalus purshii var. lectulus, Erigeron compositus</i>, and/or <i>Erigeron pygmaeus</i>. Graminoids present commonly include <i>Poa glauca ssp. rupicola, Achnatherum pinetorum, Carex tahoensis</i>, and/or <i>Festuca brachyphylla ssp. brachyphylla</i>.  Accession Code: VB.CC.33140.CEGL003488 Plot-observations of this Community Concept: 0
