Hierarchy Level: Association
Type Concept: 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. Stands of this vegetation are found between 2650 and 3110 m (8700-10,200 feet) of elevation on varied slopes and aspects, but largely southerly facing. Stands are near seeps or streams with perennial moisture. Soils are gravelly silt loams to loamy sands, and often carbonate-rich. This dwarf-shrubland is heavily dominated by Artemisia rothrockii. The only shrubs which co-occur in this association are Symphoricarpos rotundifolius, Ribes montigenum, and Holodiscus discolor. Graminoids dominate the open herbaceous layer, and species composition may be highly variable among stands. Carex filifolia, Danthonia intermedia, and/or Poa wheeleri are the most common graminoid associates. Forbs only total a small amount of cover in this association, typified by the diagnostic forb Monardella odoratissima. Other forbs which are often present, at very low cover values, may include Antennaria rosea, Penstemon rydbergii, Juncus sp., and/or Horkelia fusca. Twenty-five other species have been recorded on plots of this association, but none achieve more than 30% constancy. The forb Castilleja miniata and the graminoid Poa wheeleri each achieve 5% cover in 30% of plots. All other recorded species (mostly graminoids) only contribute a trace to the overall cover.

Geographic Range: This association is only known from the vicinity of Yosemite National Park. Information about its global range is not available without additional inventory. Anecdotal information suggests that this association or at least the alliance may range from the northern to the southern High Sierra (Sawyer and Keeler-Wolf 1995).
