CEGL001584 Salix drummondiana / Carex scopulorum var. prionophylla Wet Shrubland

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Drummond''s Willow / Fire-thread Sedge Wet Shrubland

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This association is relatively abundant in the subalpine zone of the northeast Cascades and less common in the Canadian Rockies of Washington. It may extend into British Columbia along the border. This wet, high-elevation shrub fen is usually located between 1220-1922 m (4000-6300 feet) elevation and is dominated by tall willows (over 2 m). It is usually found along very low- to moderately low-gradient streams or with ponds or lakes in fen shrublands. Soils are typically well-aerated, nutrient-rich sedge peat soils with a shallow water table and surface water apparent during the growing season. Salix drummondiana is the most common shrub although Salix boothii can be dominant. A shorter willow, Salix farriae, can be common and subdominant in some stands. Picea engelmannii trees usually appear in the fen as scattered individuals. Carex scopulorum var. prionophylla dominates the community and may share some space with Carex utriculata. Calamagrostis canadensis is the only other species that occurs regularly, although in low abundance. Sphagnum mosses are common and can be abundant.
