More than a decade of conservation biology and research in Sonora and Arizona: The endangered Sonoran Tiger Salamander and threatened Chiricahua Leopard Frog

Only two species of amphibians from Arizona are listed under the federal Endangered Species Act. The Sonoran Tiger Salamander was listed as an endangered species without critical habitat in 1997. The Chiricahua Leopard Frog was listed as a threatened species in 2002; critical habitat was designated in 2012. In this review, we summarize conservation and research conducted on these two species with a focus on work in the southeastern Arizona/northeastern Sonora borderlands, but we also touch upon seminal work on the Chiricahua Leopard Frog at Buenos Aires National Wildlife Refuge (BANWR).
