CEGL003887 Zizania aquatica Gulf Coast Tidal Marsh
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Annual Wild Rice Gulf Coast Tidal Marsh
Colloquial Name: Gulf Coast Wild Rice Tidal Marsh
Hierarchy Level: Association
Type Concept: This type includes freshwater tidal marshes of the Gulf of Mexico characterized by Zizania aquatica. This vegetation may occur in tidal rivers along the Gulf Coast. This association occurs in the lower reaches of freshwater tidal marshes, in fresh to slightly brackish areas that are low within the marsh and are infrequently exposed at lowest tides. It occurs on alluvial soils that are commonly silts or silty clays, although occasionally have a greater sand component. Zizania aquatica is dominant in stands of this type, although only conspicuously so in mid to late summer, when it overtops the early season vegetation. This community can be codominated by species such as Pontederia cordata, Peltandra virginica, Polygonum spp., and/or Bidens spp. Common associates are generally a mixture of freshwater and brackish species. Nuphar advena is a common associate.

Floristics: Zizania aquatica is dominant in stands of this type, although only conspicuously so in mid to late summer, when it overtops the early season vegetation. This community can be codominated by species such as Pontederia cordata, Peltandra virginica, Polygonum spp., and/or Bidens spp. Common associates are generally a mixture of freshwater and brackish species. Nuphar advena (= Nuphar lutea ssp. advena) is a common associate.
Dynamics: Plant composition of freshwater tidal marshes generally occurs as a mosaic of patches dominated by a few or a single species. Species composition is determined by species life history characteristics, especially lifeform, phenology and mode of regeneration in response to microhabitat conditions, and the frequency and duration of flooding. This plant association shows extreme seasonal variability with Zizania aquatica becoming a conspicuous component only in mid to late summer and generally senescing by mid to late autumn. This vegetation provides an important food source for migratory birds.
Environmental Description: This association occurs in the lower reaches of freshwater tidal marshes, in fresh to slightly brackish areas that are low within the marsh and are infrequently exposed at lowest tides. It occurs on alluvial soils that are commonly silts or silty clays, although occasionally have a greater sand component.
Geographic Range: This community is known from coastal Louisiana and Alabama; more information is needed to confirm its occurrence in Mississippi and Florida.
