Type Concept: This Cascade willow dwarf-shrubland occurs in Washington and possibly British Columbia. The vegetation is dominated by the short, mat-forming shrub Salix cascadensis. Festuca saximontana var. saximontana and Carex phaeocephala are frequent. Erigeron aureus and Minuartia obtusiloba are locally important. This association occurs in the northern Cascades above treeline. Sites have well-drained soils and vary in aspect and slope depending on climate.
