Name: Purshia tridentata - Artemisia tridentata / Achnatherum nelsonii Shrubland
Reference: NatureServe Biotics 2019
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. The known stands of this association are found at 2590-2620 m (8500-8600 feet) elevation on north to east aspects. Stands prefer moderate to steep upper slopes. The soils are well-drained loamy sands derived from metamorphic or igneous rocks. This low, moderately dense (40-60% cover of shrubs) shrubland is codominated by <i>Purshia tridentata</i> and <i>Artemisia tridentata</i>, which form an open to intermittent canopy between 0.5-1 m in height. <i>Symphoricarpos rotundifolius</i> also contributes a trace of cover to the shrub canopy. The herbaceous layer is fairly sparse and dominated by graminoids, including <i>Achnatherum nevadense, Elymus elymoides, Bromus carinatus, Bromus tectorum</i> (exotic), and <i>Leymus triticoides</i>. Forbs commonly found in this association in trace amounts include <i>Eriogonum spergulinum, Phacelia humilis, Phacelia ramosissima, Phlox stansburyi, Crepis acuminata, Cryptantha echinella, Mentzelia albicaulis, Navarretia breweri, Pleiacanthus spinosus</i>, and/or <i>Viola purpurea</i>.
