Eleocharis quinqueflora - Carex scopulorum Wet Meadow
Translated Name: Few-flower Spikerush - Mountain Sedge Wet Meadow
Unique Identifier: CEGL001837
Classification Approach: International Vegetation Classification (IVC)
Summary: This association has been described from the Sierra Nevada in the vicinity of Lake Tahoe and Yosemite National Park. Stands of this association are found along streams or in the wetter parts of meadows between 2100 and 3200 m (6900-10,500 feet) elevation. Aspect is not diagnostic for the type as slopes are very gentle to flat. Soils are poorly drained and have high organic content. Vegetation cover often exceeds 80% and is dominated by graminoid species. Either Eleocharis quinqueflora or Carex scopulorum may be dominant, or they may be codominant.



Classification

Classification Confidence: Low
Classification Comments: Carsey et al. (2003a) has an Eleocharis quinqueflora Herbaceous Vegetation that is very similar to this association, although Nachlinger (1985) feels that it is only related at higher levels of the classification.

Vegetation

Vegetation Summary: This herbaceous wetland is typified by the codominance of Carex scopulorum and Eleocharis quinqueflora and the presence of surface water for extended periods during the growing season. Common graminoid associates may include Carex scopulorum, Carex aquatilis, Carex buxbaumii, Carex utriculata, Deschampsia cespitosa, and Eleocharis rostellata. Forb cover is low, but can include Caltha leptosepala, Pedicularis groenlandica, Oreostemma alpigenum (= Aster alpigenus), Dodecatheon alpinum, and Polygonum bistortoides.
