CEGL003483 Artemisia arbuscula ssp. arbuscula / Eriogonum microthecum Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Little Sagebrush / Slender Buckwheat Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands of this association are found between 2345 and 2805 m (7700-9200 feet) elevation on gentle to steep slopes. Aspects are generally north, but may be variable on flatter sites. Soils are stony sands to silt loams derived from igneous or metamorphic parent materials. Precipitation ranges from 20-50 cm (150) annually, with a large proportion falling as winter snow. Stands near Yosemite are dominated by Artemisia arbuscula with traces of Eriogonum microthecum. Chrysothamnus viscidiflorus is also usually present. The open herbaceous layer is dominated by perennial grasses, primarily Elymus elymoides and Koeleria macrantha. Other common graminoid associates may include (in order of decreasing cover and constancy) Achnatherum hymenoides, Poa secunda, and/or Achnatherum pinetorum. A variety of forbs are present at low cover levels and constancy. The most common forb associates include Pleiacanthus spinosus, Astragalus purshii, and/or Linanthus pungens. The height of this association is usually less than 0.5 m, with the graminoids often taller than the shrubs and forbs.

A variety of forbs are present at low cover levels and constancy. The most common forb associates include Pleiacanthus spinosus (= Stephanomeria spinosa), Astragalus purshii, and/or Linanthus pungens (= Leptodactylon pungens).
