Extinction Cause: The Vegas Valley leopard frog is extinct evidently due to habitat loss resulting from spring capture and ground water pumping by the growing city of Las Vegas, and exacerbated by the introduction of the Bullfrog, Lithobates catesbeianus (previously Rana catesbeiana.). Although some suitable habitat persists within or near the former range of this species, only the Bullfrog can be found there. (Jennings & Hammerson 2004) Habitat was as described: This frog was historically known from a number of localities at the headwaters of Las Vegas Creek and numerous artesian springs in the Las Vegas Valley (Linsdale 1940), as well as Tule Springs, Clark County, southern Nevada, United States of America (Stebbins 1951; Jennings et al. 1995), at elevations between 370 and 760 m (Platz 1984; Stebbins 1985). The densest populations of the Vegas Valley leopard frog were at three large springs that were at the western edge of what is currently Las Vegas, at the headwaters of Las Vegas Creek (Wright and Wright 1949). The species was restricted to freshwater streams, springs, seeps, and adjacent riparian (cottonwoods, willows, and tules) habitat associated with Upper Las Vegas Valley (Wright and Wright 1949).
