Chiricahua Leopard Frog Egg Mass Discovered!
Southwest Region, April 27, 2009
Print Friendly Version
On April 27, 2009,  Tonto National Forest Wildlife Biologist, with the Pleasant Valley Ranger District, discovered a Chiricahua leopard frog egg mass, numbering approximately 1,400 eggs, within a stream pool along the Mogollon Rim.  The entire egg mass was collected and transported to the Phoenix Zoo for head-starting, ultimately for  subsequent release of metamorphosed frogs back into the wild.  Frogs head-started from this particular egg mass will be introduced into habitat that has been secured for Chiricahua leopard frogs within the Payson Ranger District of the Tonto National Forest in the effort of establishing a second functioning metapopulation of this species on the Forest.  Several participants in this process such as the Tonto National Forest, the Phoenix Zoo, the Arizona Game and Fish Department, the U.S. Fish and Wildlife Service, and others work cooperatively to conserve and recover the Chiricahua leopard frog within its northern distribution along the Mogollon Rim.  We remain optimistic that the egg mass recently collected will provide yet another boost in the implementation of this important effort.
