A3929 Schoenoplectus subterminalis Aquatic Vegetation Alliance
Type Concept Sentence: This is an aquatic herbaceous alliance of submerged stands dominated by Schoenoplectus subterminalis, often with other floating aquatic species and grading into Nuphar polysepala community types in very shallow permanent ponds. It occurs in Washington but could be more widespread in the western U.S.
Common (Translated Scientific) Name: Swaying Bulrush Aquatic Vegetation Alliance
Colloquial Name: Western Swaying Bulrush Aquatic Vegetation
Hierarchy Level: Alliance
Type Concept: This aquatic submerged herbaceous alliance is dominated by Schoenoplectus subterminalis and usually has other species present such as Nuphar polysepala and Utricularia macrorhiza. It occurs in very shallow permanent ponds, most frequently where there is large annual water-level fluctuation. Substrates are saturated organic soil. It occurs in Washington but could be more widespread in the western U.S.
