This video says about itself:
10,000th Chiricahua leopard frog reared at the Phoenix Zoo to be released by the Arizona Game and Fish Department. Release took place in the Tonto National Forest near Payson, AZ. A total of 1,700 frogs were released on August 23,2010.
From the New York Times in the USA:
A Las Vegas native thought to have been extinct for decades is alive and living in Arizona.
The Vegas Valley leopard frog was last seen in 1942, and officially declared extinct in 1996. The development of the city of Las Vegas is thought to have been the main factor in the species’ demise.
Now researchers report in Conservation Genetics that the frog is genetically identical to a lineage of the Chiricahua leopard frog found in the Mogollon Rim of central Arizona.
