Name: A.1437
Reference: EcoArt 2002
Description: This alliance includes semipermanently flooded grasslands in spring-fed rivers, with near constant water level and temperature, dominated either by ~Zizania aquatica$ (in Florida) or by the narrow endemic ~Zizania texana$ (in Texas), with various emergent and submerged aquatics including ~Potamogeton illinoensis, Ludwigia palustris, Sparganium americanum, Pontederia cordata, Sagittaria lancifolia, Sagittaria$ sp., ~Polygonum$ sp., ~Cicuta maculata var. maculata (= Cicuta mexicana), Hydrocotyle umbellata$, and filamentous green algae. The exotics ~Hydrilla verticillata$ and ~Egeria densa$ may also be present. This community is threatened by exotic species, changes in hydrology (related to groundwater pumping), sedimentation, and recreational impacts.
