CEGL001850 Calamagrostis purpurascens Alpine Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Purple Reedgrass Alpine Meadow
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This dry alpine tundra plant association is known from the eastern portion of the northern Cascade Range in Washington and British Columbia, and has been reported from California. Small stands of the association occur on moderate to steep, well-drained, rocky south- to west-facing windward slopes at 2225-2610 m (7300-8550 feet) elevation. Relatively low seasonal accumulations of snow melt rapidly. The sites are snow-free by April to early May. Calamagrostis purpurascens occurs with high cover and frequency. Carex scirpoidea, Minuartia obtusiloba, Oxytropis monticola, and Potentilla diversifolia var. diversifolia are prominent species in the floristically rich plant association.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: The association is described by Douglas and Bliss (1977) from 5 stands located in the eastern portion of the northern Cascade Range. Moseley (1985) describes 1 stand located in the Lemhi Range of east-central Idaho. Additional data are needed to characterize the composition and environmental relations of Calamagrostis purpurascens-dominated stands of central Idaho. Moseley''s (1985) data suggest that these communities are dissimilar to the northern Cascade Range communities. The Calamagrostis purpurascens-dominated communities of central Idaho are tentatively treated as a distinct plant association.
