Name: Purshia tridentata - Ericameria nana / Penstemon deustus Shrubland
Reference: NatureServe Biotics 2019
Description: This association occurs in the intermountain western U.S. <i>Purshia tridentata</i> is the dominant species in this shrubland vegetation type and <i>Ericameria nana</i> is always present. <i>Eriogonum microthecum</i> also occurs frequently but with very low cover. Other shrubs such as <i>Artemisia tridentata ssp. wyomingensis</i> and <i>Ericameria nauseosa</i> may occur sporadically in the shrub canopy of this association. The sparse herbaceous layer may include various graminoid species and those that occur frequently include <i>Poa secunda, Bromus tectorum</i>, and <i>Elymus elymoides</i>. Forbs are extremely sparse but <i>Penstemon deustus</i> is a characteristic species of this association. <i>Linanthus pungens</i> and <i>Phacelia hastata</i> are also common. 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.
