Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Pacific Alpinegold - White-stem Goldenbush - Compact Phacelia Alpine Fell-field
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This herbaceous 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 alpine forb association occur in stony environments that include talus slopes and fell-fields. Sites are relatively xeric uplands. Elevations average about 3200 m (10,500 feet), and slopes are moderate and face south and west. Soils are well-drained sandy loams. This perennial forb vegetation is characterized by several cold- and drought-tolerant forbs and subshrubs, primarily Hulsea algida, Phacelia hastata var. compacta, and Ericameria discoidea. Total vegetative cover is generally less than 50%. Eriogonum ovalifolium is the most common subshrub in some stands, with Muhlenbergia richardsonis the most common graminoid. Other graminoids present may include Achnatherum occidentale, Elymus elymoides, Carex filifolia, and/or Poa wheeleri. The forbs present in trace amounts may include Achillea millefolium, Minuartia nuttallii, Penstemon rydbergii, and/or Potentilla glandulosa.
