Name: Cercocarpus ledifolius - Purshia tridentata / Poa secunda Scrub
Reference: NatureServe Biotics 2019
Description: The vegetation of this association is characterized by low to moderate shrub cover dominated by <i>Cercocarpus ledifolius</i>. <i>Purshia tridentata</i> is also important in the shrub stratum of this community, but it often occurs at low cover values. Other shrub species may also be present on occasion. <i>Juniperus osteosperma</i> may occur sporadically, but not with enough regularity or abundance to form a tree canopy. The sparse herbaceous layer has few graminoids, but <i>Poa secunda</i> is always present and <i>Elymus elymoides</i> commonly occurs. The introduced annual grass <i>Bromus tectorum</i> also occurs with some regularity. Forb cover is very low but <i>Lactuca serriola, Phacelia hastata</i>, and <i>Stephanomeria minor</i> are all commonly found in the understory of this plant community. 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.
