A1441 Zizania aquatica - Zizania palustris Marsh Alliance
Type Concept Sentence: This wild rice marsh community is found in the upper midwestern United States and adjacent Canada in deeper, sheltered waters of slow-moving streams, protected bays, and flowage lakes where the vegetation is dominated by Zizania aquatica or Zizania palustris.
Common (Translated Scientific) Name: Annual Wild Rice - Northern Wild Rice Marsh Alliance
Colloquial Name: Wild Rice Marsh
Hierarchy Level: Alliance
Type Concept: This wild rice marsh community is found in the upper midwestern United States and adjacent Canada. A thick mat of rice stalks often covers the bottom. The marsh is dominated almost entirely by the tall emergent graminoids Zizania aquatica or Zizania palustris. Floating-leaved and submerged aquatic cover can be high, but species composition is variable. Species include Ceratophyllum demersum, Nuphar variegata, Potamogeton natans, Potamogeton zosteriformis, Spirodela polyrrhiza, Utricularia macrorhiza, and others. Stands are found in deeper, sheltered waters of slow-moving streams, protected bays, and flowage lakes, particularly at stream mouths. Water depths generally exceed 0.5 m. Substrate is rich sedimentary peat or mucky, silty mineral soils.
Diagnostic Characteristics: Emergent marshes in protected bays or other still or slow-moving waters that are dominated by Zizania aquatica or Zizania palustris. Cover by floating-leaved and submergent species may be high but they are beneath at least 25% cover by emergents.

Physiognomy and Structure: This alliance is dominated by tall, emergent graminoids, which can become very dense. Floating-leaved and submergent vegetation is common and tends to be more abundant where the emergent stratum is less dense.
Floristics: This marsh alliance is dominated almost entirely by the tall emergent graminoids Zizania aquatica or Zizania palustris. Floating-leaved and submerged aquatic cover can be high, but species composition is variable. Species include Ceratophyllum demersum, Nuphar variegata (= Nuphar lutea ssp. variegata), Potamogeton natans, Potamogeton zosteriformis, Spirodela polyrrhiza, Utricularia macrorhiza (= Utricularia vulgaris), and others.
