Description: The polygons provided in this data layer represent subsurface designated critical habitat areas based on our best assessment at the time of areas that are within the geographical range of the Jollyville Plateau Salamander and are considered to contain features essential to the conservation of this species. The extent to which the subterranean populations of this species exists below ground away from outlets of the spring system is unknown. Because the hydrology of central Texas is very complex and information on the hydrology of specific spring sites is largely unknown, we will continue to seek information to increase our understanding of spring hydrology and salamander underground distribution to inform conservation efforts for these species. At the time of this final critical habitat rule, the best scientific evidence available suggests that a population of these salamanders can extend at least 984 ft (300 m) from the spring opening through underground conduits or voids between rocks. https://traviscountytx.maps.arcgis.com/home/item.html?id=07c83dba8d2e40b589ac4358e12aa333
