Endangered and Threatened Wildlife and Plants; Designation of Critical Habitat for the Georgetown and Salado Salamanders

Краткое содержание

We, the U.S. Fish and Wildlife Service (Service), are revising our proposed designation of critical habitat for the Georgetown salamander (Eurycea naufragia) and Salado salamander (Eurycea chisholmensis) in Bell and Williamson Counties, Texas. Based on published genetic analyses, we are revising the distribution of the Georgetown and Salado salamanders and are adjusting previously proposed critical habitat units accordingly. We also propose changes to our description of the physical or biological features essential to the conservation of the species. We propose a total of approximately 1,519 acres (ac) (622 hectares (ha)) of critical habitat for the species in Bell and Williamson Counties, Texas. The total amount of critical habitat we are proposing for both salamanders has increased by approximately 116 ac (47 ha). The reasons for this increase are the addition of a new occupied site for the Salado salamander and refined mapping of previously proposed critical habitat units based on more precise spring locations. We also announce the availability of a draft economic analysis (DEA) of the revised proposed designation of critical habitat for the Georgetown and Salado salamanders.
