CEGL005611 Purshia tridentata - Philadelphus lewisii / Poa secunda Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Antelope Bitterbrush - Lewis'' Mock Orange / Sandberg Bluegrass Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association has an open shrub canopy and may occasionally have a sparse tree canopy resulting from scattered Pinus flexilis individuals. The shrub stratum is dominated by Purshia tridentata and Philadelphus lewisii, but Chamaebatiaria millefolium is common as well. Other shrubs such as Ericameria nauseosa, Ribes aureum, Ericameria nana, and Eriogonum microthecum may also be present. The sparse herbaceous layer has few graminoids, but Poa secunda is always present and Elymus elymoides is common. Forb cover is sparse in this plant community, but Penstemon deustus, Potentilla glandulosa, Pteryxia terebinthina, and Packera cana all occur with high constancy. 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.

Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Lewis'' mock orange is a unique shrub species in that it is tolerant of a wide range of precipitation levels but intolerant of both fire and shade. It thrives on the exposed basaltic fissures that are common in the Snake River Plain of eastern Idaho.
