American bullfrogs are a threat to native wildlife in southeast Arizona

Invasive American bullfrogs are a big threat to our native wildlife in southeast Arizona, including some endangered reptiles and amphibians like Chiricahua leopard frogs and northern Mexican garter snakes. These bullfrogs can spread quickly and reproduce easily, making it tough to manage their population.

To help protect our local ecosystems, a new study is underway to better understand how these bullfrogs move around and breed. Led by Arizona CRU researchers on the campus of the University of Arizona, and a University of Arizona graduate student, this project teams up with the Arizona Game and Fish Department and other partners, including the U.S. Forest Service and the U.S. Fish and Wildlife Service.

By studying how far bullfrogs travel, when they breed, and at what size they breed, we can figure out the best ways to target their populations for removal and prevent them from taking over even more areas. This important work will help keep our native species safe and sustain the beauty of our natural landscapes!
