Name: Purshia tridentata / Leymus cinereus Shrub Grassland
Reference: NatureServe Biotics 2019
Description: <i>Purshia tridentata</i> forms a low and relatively open shrub canopy in this shrub herbaceous vegetation type. Several other shrub species are commonly present as scattered individuals; the most frequent of which is <i>Artemisia tridentata ssp. vaseyana</i>. Herbaceous cover generally equals or exceeds that of the shrub stratum. The perennial bunchgrass <i>Leymus cinereus</i> dominates the herbaceous layer, with a growth form of large clumps up to 1 m across. Other grasses are often present and include <i>Bromus tectorum</i> and <i>Poa secunda</i>. Common forbs include <i>Collinsia parviflora, Crepis acuminata, Delphinium andersonii, Eriogonum umbellatum, Lomatium dissectum</i>, and <i>Phacelia hastata</i>. This association, like all associations in ~Inter-Mountain Basins Volcanic Rock and Cinder Land (CES304.791)$$, is limited to barren and sparsely vegetated volcanic substrates of basalt and basaltic andesite origin, including tuffs, cinder cones, spatter cones, pressure plateaus, or cinder fields. It may occur in large-patch, small-patch or linear spatial patterns.
