Nongame and Rare Species Program: Rare Plant Communities of Texas
Edwards Plateau
The Texas Hill Country or Edwards Plateau is a 20 million acre region characterized by Cretaceous limestone formations which erode into shallow calcareous soils, rolling topography, and limestone-bedded streams, many spring-fed. The plateau is geologically isolated and high rates of animal endemism are associated with karst aquifers, springs, and caves. The plant communities detailed below represent those identified in the current Texas Conservation Action Plan as being of greatest conservation need.
