Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This woodland is known from California, Nevada, Idaho and southern Utah. The following description is from southern Nevada and southern Utah stands. This woodland occurs on high mountain slopes and ridges or low washes at 2072 to 2835 m (6800-9300 feet) elevation. Soils are rapidly drained sandy loams derived from alluvium or rhyolitic welded ash-flows. This woodland appears as clumps of taller Cercocarpus ledifolius amongst a sea of the lower statured Artemisia tridentata. Other tree species may include Juniperus osteosperma, Juniperus scopulorum, pinyon spp., and Pinus ponderosa. Other shrubs include Amelanchier pallida, Purshia tridentata, Chrysothamnus spp., Gutierrezia sarothrae, Tetradymia canescens, Sambucus nigra ssp. cerulea, Symphoricarpos spp., and Ericameria nauseosa. The herbaceous layer has sparse cover and includes the bunchgrasses Achnatherum hymenoides and Elymus elymoides.

Floristics: This woodland appears as clumps of taller Cercocarpus ledifolius amongst a sea of the lower statured Artemisia tridentata. Other tree species may include Juniperus osteosperma, Juniperus scopulorum, pinyon spp., and Pinus ponderosa. Other shrubs include Amelanchier pallida, Purshia tridentata, Chrysothamnus spp., Gutierrezia sarothrae, Tetradymia canescens, Sambucus nigra ssp. cerulea (= Sambucus caerulea), Symphoricarpos spp., and Ericameria nauseosa. The herbaceous layer has sparse cover and includes the bunchgrasses Achnatherum hymenoides and Elymus elymoides. In Nevada, herbs listed include no grasses, and the following forbs were noted for their uniqueness to this habitat: Selaginella watsonii, Phlox pulvinata, Androsace septentrionalis ssp. puberulenta, Castilleja viscidula, and Penstemon pudicus.
