More than 150 Chiricahua leopard frogs have been released into the Galiuros Mountains by Arizona officials.
The Arizona Game and Fish Department recently announced that the threatened adult and juvenile frogs were released at the new location where they haven't been seen since the 1990s.
Until the 1970s, Chiricahua leopard frogs lived in ponds and creeks across central and southeastern Arizona, but populations have declined significantly due to drought, disease, habitat loss and threats from other species.
Chiricahua leopard frogs were listed as threatened under the Endangered Species Act in 2002.
The rare spotted frog is only found in Arizona and New Mexico.
