CEGL005597 Ericameria nana / Poa secunda - Penstemon deustus Sparse Vegetation
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Dwarf Goldenbush / Sandberg Bluegrass - Scabland Penstemon Sparse Vegetation
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association of the intermountain western U.S. is characterized by a dwarf-shrub stratum with low to moderate cover dominated by Ericameria nana and Eriogonum microthecum. Taller shrubs are occasionally present and Holodiscus dumosus and/or Purshia tridentata often occur as scattered individuals throughout the plant community. The sparse herbaceous layer typically has higher graminoid cover and diversity than other cinder land communities. Commonly occurring graminoid species include Poa secunda, Elymus elymoides, and Hesperostipa comata. Penstemon deustus is a characteristic forb species of this association. Other common forbs include Potentilla glandulosa, Linanthus pungens, Stephanomeria minor, and Phacelia hastata. 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. Soil is more available for vegetation establishment in this plant community than on other cinder land plant communities, as evidenced by higher average graminoid cover.
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 typically low, less than 1%.
This plant community description is based on data from Craters of the Moon (Bell et al. 2009) and on related plant communities that have been previously described. The description provided herein may vary slightly from similar plant communities found elsewhere due to the local scale at which data were collected.
