Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Texas Wild Rice - Illinois Pondweed Marsh
Colloquial Name: Texas Wild Rice Spring-run Marsh
Hierarchy Level: Association
Type Concept: This narrowly endemic community occurs in a several-kilometer stretch of the spring-fed, calcareous waters of the San Marcos River, Texas. Zizania texana is dominant, but beds of various emergent, floating, and submersed aquatics are intermixed, including Potamogeton illinoensis, Ludwigia palustris, Sparganium americanum, Hydrilla verticillata (exotic), Egeria densa (exotic), Sagittaria sp., and filamentous green algae. This community is threatened by exotic species, changes in hydrology (related to groundwater pumping), sedimentation, and recreation.
