Nearly one third of all known Australian frog populations are in varying stages of decline, including the endangered Spotted Tree Frog.
This vulnerable species has a restricted distribution, confined to the Sydney Basin (from Pokolbin in the north, the Nowra area to the south, and west to Mt Victoria in the Blue Mountains). It usually measures less than 30mm long.
This tiny species only reaches only about 25mm in length.
Taronga Zoo is hopping aboard Amphibian Ark’s Leap Day 2012 event – entitled "Leaping Ahead of Extinction: A celebration of good news for amphibians in 2012" – with six key conservation programs designed to give endangered Australian frog populations (such as the Booroolong Frog, pictured above) a vital leg-up.
Taronga Zoo’s Southern Corroboree Frog breeding program is underway for 2012, with the Zoo's Herpetofauna staff planning to boost native populations of this critically endangered species by releasing eggs into the wild in autumn/winter.
Taronga Zoo is currently operating breed-and-release programs for six endangered and vulnerable Australian frog species, including the Booroolong Frog, the Alpine Tree Frog, the Yellow-Spotted Bell Frog, the Green and Golden Bell Frog, the Southern Corroboree Frog and the Northern Corroboree Frog (pictured above).
Thought extinct for 30 years, the Yellow-spotted Bell Frog was rediscovered in the Southern Tablelands just two years ago, and Taronga has since established a small insurance population.
This iconic frog has disappeared from most of its former habitat. Taronga has bred and released 26 000 Green and Golden Bell Frogs and tadpoles since 1994.
In January 2012, Taronga released over 6000 Green and Golden Bell Frog tadpoles at Woonona. The Zoo has now bred 26 000 of these frogs and tadpoles for reintroduction to the wild since 1994.
