General Description
Arizona Toad (Anaxyrus microscaphus) is a medium-sized (8 cm) warty toad that is distributed across Arizona and into neighboring California, Nevada, Utah, and New Mexico. They can be found in rocky streams in pine-oak forests or willow and cottonwood-dominated forests, or anthropogenic habitats. They may breed in main stem rivers or side channels and pools depending on flow conditions. They are threatened by habitat alteration, climate change, drought, forest fires, disease, and replacement by and hybridization with Woodhouse?s toad (Anaxyrus woodhousii).
