A3436 Kobresia myosuroides - Kobresia simpliciuscula Alkaline Graminoid Fen Alliance
Type Concept Sentence: This Rocky Mountain alliance contains strongly alkaline fens dominated by herbaceous species; indicators include Kobresia myosuroides and Kobresia simpliciuscula, the later indicating extremely rich conditions. The water chemistry is distinct in that it contains high levels of calcium and magnesium.
Common (Translated Scientific) Name: Simple Bog Sedge - Bellardi Bog Sedge Alkaline Graminoid Fen Alliance
Colloquial Name: Bog Sedge Alkaline Graminoid Fen
Hierarchy Level: Alliance
Type Concept: This alliance consists of strongly alkaline fens dominated by herbaceous species; indicators include Kobresia myosuroides and Kobresia simpliciuscula, the later indicating extremely rich conditions. Other species present may include Carex aquatilis, Carex simulata, Eleocharis quinqueflora, Juncus arcticus, Ptilagrostis porteri, Salix brachycarpa, Salix candida, Thalictrum alpinum, and Trichophorum pumilum. The water chemistry is distinct in that it contains high levels of calcium and magnesium. It is documented to occur in the Rocky Mountains of Colorado, but is likely to occur in Wyoming, Montana, Idaho, Utah, New Mexico, Alberta and British Columbia
