The northern boundary of the desert tortoise range on the Nevada Test Site
A study was conducted in 1993 to more accurately define the northern boundary of the range of desert tortoises (Gopherus agassizii) on the Nevada Test Site. Eighty-six transects totaling 338.2 km were walked along this boundary and 53 tortoise signs were recorded. Tortoise signs were found all along the northern edge of Jackass and Frenchman flats. Signs were found north of those valleys only in the Calico Hills at the south end of Topopah Valley and in the CP Hills at the extreme southern end of Yucca Flat. A revised map of the range of desert tortoises on NTS is presented. This information can be used by the US Department of Energy to determine whether activities conducted along or near this boundary will affect desert tortoises.
