CEGL005603 Pinus flexilis / Chamaebatiaria millefolium / Poa secunda Open Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Limber Pine / Desert-sweet / Sandberg Bluegrass Open Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: The vegetation of this association of the intermountain western U.S. is characterized by sparse total cover, less than 10%. Pinus flexilis individuals are scattered throughout this vegetation type, but do not occur with high enough abundance to form a tree canopy. The shrub stratum is dominated by Artemisia tridentata ssp. vaseyana, Chamaebatiaria millefolium, and Philadelphus lewisii. Chamaebatiaria millefolium occurs with sparse cover, but is a characteristic species of this association. Other, less frequently occurring, shrubs may include Holodiscus dumosus and Purshia tridentata. The minimal herbaceous layer includes the graminoids Poa secunda and Pseudoroegneria spicata. Forbs cover is also low but highly variable in terms of species composition, and may include species such as Crepis acuminata, Dryopteris filix-mas, Aliciella leptomeria, Linanthus pungens, Lithophragma tenellum, Pteryxia terebinthina, and Viola nuttallii. 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 shrub Chamaebatiaria millefolium 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. Additional global information will be added as it becomes available.
