Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Shorthair Reedgrass - Drummond''s Rush Grassland

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. Examples of this association occur on lower slopes and basin floors at about 3050 m (10,000 feet) of elevation. Aspect does not seem to be important in differentiating this type. Slopes are gentle to moderate. Sites are seasonally saturated and soils are sandy to silt loams. This dense grassland association is codominated by Calamagrostis breweri and Juncus drummondii. Ptilagrostis kingii may be important in some stands. Other common graminoid associates may include Agrostis humilis, Trisetum spicatum, and traces of Carex abrupta, Carex subnigricans, Deschampsia cespitosa, Luzula congesta, Ptilagrostis kingii, Poa pratensis, Poa stebbinsii, and/or Phleum alpinum. The forb component is fairly minor, but the more common species present may include Antennaria corymbosa, Polygonum bistortoides, Potentilla diversifolia, Sibbaldia procumbens, and/or Trifolium monanthum.
