The Chiricahua leopard frog (Lithobates chiricahuensis syn. Rana chiricahuensis) is a species of frog in the family Ranidae, the true frogs. Distribution and habitat It is native to Mexico and the United States (Arizona and New Mexico). Its natural habitats are temperate forests, rivers, intermittent rivers, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, freshwater springs, ponds, and open excavations. Conservation It is threatened by habitat loss and chytrid fungus to such an extent that it has been eliminated from 80% of its former habitat. The Phoenix Zoo, Arizona's Department of Game and Fish, and the USFWS are trying to mitigate threats through captive breeding and reintroduction efforts. Phylogeny A 2011 genetic analysis provided evidence that the northwestern Mogollon Rim population of L. chiricahuensis is indistinguishable from specimens of the extinct Vegas Valley leopard frog (Lithobates fisheri). The Ramsey Canyon leopard frog (Lithobates subaquavocalis) has also been shown to be conspecific with the Chiricahua leopard frog. References Further reading Hillis, D. M., et al. (1983).
