CEGL005601 Juniperus scopulorum / Poa secunda - Penstemon deustus Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Rocky Mountain Juniper / Sandberg Bluegrass - Scabland Penstemon Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association of the intermountain western U.S. is characterized by an open tree canopy dominated by Juniperus scopulorum. Juniperus osteosperma is often present in the canopy as well, but with lower constancy and lower cover. Tree canopy cover values are more than 5%, but typically less than 20%, and canopy height is usually 2-10 m. Shrubs such as Purshia tridentata, Ericameria nauseosa, or Ericameria nana occur regularly in the shrub stratum but generally with very low cover. The sparse herbaceous layer is dominated by graminoids such as Poa secunda and the introduced annual Bromus tectorum. Associated forbs may include Potentilla glandulosa and Linanthus pungens. Penstemon deustus is always present in the understory and is a characteristic species in this association; however, its cover is often very low, generally under 1%. Total forb cover is generally sparse. This association is included in ~Inter-Mountain Basins Volcanic Rock and Cinder Land (CES304.791)$$, which 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.
