Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Wolf''s Willow / Bluejoint Wet Shrubland

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This association is known from eastern Idaho, western Wyoming and the western slope of Colorado. It occurs between 2650 and 2990 m (8700-9800 feet) elevation in narrow and broad valley bottoms on flat to rolling floodplains and stream terraces. It can also occur on hillside seeps. Soils range from clay, silty loam to sand, usually with signs of a fluctuating water table. Associated stream channels can be wide and sinuous or braided from beaver activity. This is a low-statured shrubland dominated by Salix wolfii. The canopy cover can be nearly continuous or moderately patchy. Other willows may be present but not codominant and include Salix planifolia, Salix monticola, and Salix geyeriana. The herbaceous undergrowth is thick and dominated by graminoids; Calamagrostis canadensis is the most abundant and constant species present. Other graminoids include Carex microptera, Carex utriculata, Carex aquatilis, Bromus ciliatus, Alopecurus magellanicus, and Poa pratensis. Forbs are always present and diverse but not as abundant as the graminoid cover. Forb species include Thalictrum occidentale, Senecio triangularis, Senecio sphaerocephalus, Chamerion angustifolium, Cardamine cordifolia, Vicia americana, Mertensia ciliata, Valeriana edulis, and Heracleum maximum.

Environmental Description:  This association occurs between 2650 and 2990 m (8700-9800 feet) elevation in narrow and broad valley bottoms on flat to rolling floodplains and stream terraces. It can also occur on hillside seeps. Soils range from silty loam to clay and even sand, usually with signs of a fluctuating water table. Associated stream channels can be wide and sinuous or braided from beaver activity.
