CEGL008657 Calamagrostis breweri - Trisetum spicatum Grassland

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Shorthair Reedgrass - Narrow False Oats 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. Stands of this association occur on basin floors to midslopes between 2900 and 3170 m (9500-10,400 feet) of elevation. Aspect does not seem to be important in differentiating this type. Slopes are gentle to moderate. Sites are temporarily saturated/flooded and soils are sandy to silt loams. This association is heavily dominated by Calamagrostis breweri (50% cover), with Trisetum spicatum (5% cover) an important species. Other graminoids providing traces of cover include Luzula congesta, Ptilagrostis kingii, Carex subnigricans, and/or Phleum alpinum. Forbs provide up to about 10% cover, and the most common include Potentilla drummondii, Solidago multiradiata, Castilleja lemmonii, Oreostemma alpigenum, Antennaria media, Pedicularis groenlandica, Penstemon heterodoxus, Rumex paucifolius, and/or Senecio scorzonella.
