Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Chairmaker''s Bulrush Western Marsh

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This wetland herbaceous association ranges from California to Washington and east to Colorado. This description is based on information from Great Sand Dunes National Park and Preserve in Colorado. Additional global information will be added as it becomes available. This association is found within basin floor sabkhas, swales, or dunefields at elevations ranging from 2300 to 2340 m. This palustrine system can be seasonally flooded, temporarily flooded, or saturated. Soils are very poorly drained clays or very poorly to poorly drained loamy sands. Ground cover includes litter and duff (30-35%) and bare soil (10-40%). Herbaceous vegetation cover ranges from 55-95%, which is largely composed of Schoenoplectus americanus with 20-70% cover. Additional species that occur in lesser amounts include Cleome multicaulis, Distichlis spicata, and Juncus arcticus ssp. littoralis.
