Name: Zizania texana - Potamogeton illinoensis Marsh Reference: NatureServe Biotics 2019 Description: This narrowly endemic community occurs in a several-kilometer stretch of the spring-fed, calcareous waters of the San Marcos River, Texas. <i>Zizania texana</i> is dominant, but beds of various emergent, floating, and submersed aquatics are intermixed, including <i>Potamogeton illinoensis, Ludwigia palustris, Sparganium americanum, Hydrilla verticillata</i> (exotic), <i>Egeria densa</i> (exotic), <i>Sagittaria</i> sp., and filamentous green algae. This community is threatened by exotic species, changes in hydrology (related to groundwater pumping), sedimentation, and recreation.  Accession Code: urn:lsid:vegbank.org:commConcept:33298-{04C3059C-151A-48C2-99E2-20FEB3968A29} Plot-observations of this Community Concept: 0
