CEGL005610 Purshia tridentata - Ericameria nana / Penstemon deustus Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Antelope Bitterbrush - Dwarf Goldenbush / Scabland Penstemon Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association occurs in the intermountain western U.S. Purshia tridentata is the dominant species in this shrubland vegetation type and Ericameria nana is always present. Eriogonum microthecum also occurs frequently but with very low cover. Other shrubs such as Artemisia tridentata ssp. wyomingensis and Ericameria nauseosa 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 Poa secunda, Bromus tectorum, and Elymus elymoides. Forbs are extremely sparse but Penstemon deustus is a characteristic species of this association. Linanthus pungens and Phacelia hastata 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.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: The forb Penstemon deustus is always present and is a characteristic species of the association. However, its cover is low, generally under 1%.
