The following is a list of amphibians found in the state of Arizona. The Arizona tree frog is the state amphibian.[1] The state is home to three salamander species.
Arizona is home to a wide variety of biotic systems as it is diverse topographically, geologically, and climatically. The area's sporadic mountains create "sky islands", wherein varying altitudes create drastically different environments inhabited by specific species.[2] For example, the eastern barking frog is only found at altitudes of 1,280–1,890 m on Arizonan mountains. Although the state is mostly arid, river systems such as the Colorado River provide riparian habitats.[3]
