CEGL001911 Leucopoa kingii - Carex elynoides Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Spike Fescue - Blackroot Sedge Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This plant association occurs on broad, gentle alpine ridges of the Challis Volcanics and Beaverhead Mountains ecoregional sections in east-central Idaho. It occurs on gentle to moderately steep, convex, southwest- to north-facing ridgetops. Sites are on windward exposures at 3020-3170 m (9900-10,400 feet) elevation. Shallow to moderately deep gravelly soils are derived from limestone. Leucopoa kingii and Carex elynoides are codominant and form a dense, low-growing, fibrous-rooted turf. Associated species occur with low cover, but high constancy, including Poa fendleriana, Poa secunda, Agoseris glauca, Potentilla ovina, Oxytropis sericea, and Erigeron compositus.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: The association is described by Moseley (1985) and Urbanczyk (1993) from 9 plots located in the Beaverhead Mountains, Lost River Range, Lemhi Range, and White Knob Mountains. The association is not specifically named by either author. Stands of the association may be included in the Carex elynoides community type described by Cooper et al. (1997).
