Bolson Tortoise
Gopherus flavomarginatus Legler, 1959

Current SSAR Comments:
Newly listed taxon. The extant range is confined to the Bolson de Mapimi basin of Chihuahua, Coahuila, and Durango, Mexico. However, before the presence of humans, it ranged as far north as New Mexico, USA, and south as Aguascalientes, Mexico (Affenberg and Franz, 1978, Catalogue of American Amphibians and Reptiles (214): 1–2; Morafka, 1982, North American tortoises: Conservation and ecology. Wildlife Research Report 12. United States Department of the Interior, Fish and Wildlife Service, Washington, D.C.). The Bolson Tortoise underwent a severe and rapid human-induced extirpation from most of its range late in the Pleistocene (Morafka, 1988, Annals of Carnegie Museum 57: 47–72). In 1979, the Bolson Tortoise was listed as endangered under the United States Endangered Species Act (USFWS, 2006, Federal Register 44: 23062–23064). Sixteen adult tortoises from the Mapimi Biosphere Reserve (Mexico) were translocated to an enclosed captive-breeding program on the Appleton Research Ranch in Elgin, Arizona, between 1971 and 1976 (Appleton, 1978, Proceedings of the Desert Tortoise Council Symposium. Desert Tortoise Council, Las Vegas, Nevada). In September 2006, 37 tortoises were moved from the Appleton Research Ranch to three locations in New Mexico (Zylstra, 2006, Sonoran Herpetologist 20: 50–54).
