The Chiricahua leopard frog (Lithobates chiricahuensis) is a threatened species found exclusively in isolated areas within Arizona, New Mexico and northern Mexico. The Fort Worth Zoo is one of two zoos working with this species and celebrated the first-ever successful Chiricahua leopard frog breeding. This is the first time this species has been bred in an entirely indoor environment. Thanks to the careful manipulation of environmental settings, three females laid eggs naturally without the use of hormones. The Zoo sent 456 captive-hatched Chiricahua leopard frogs to New Mexico for release at a reintroduction site. This was the first reintroduction in New Mexico, where the wild Chiricahua leopard frog population has suffered significant declines. Since that first successful reintroduction, the Zoo continues to release hundreds of Chiricahua leopard frogs back into the historic habitat.
