Taronga frog specialists are getting ready to take 500 zoo-bred Southern Corroboree Frog eggs back to the Kosciuszko National Park.

NSW Minister for Environment and Heritage, Ms Parker, visited the breeding unit at Taronga today to see the frogs first-hand.

She said the efforts of the Office of Environment and Heritage, Taronga, Melbourne’s  Amphibian Research Centre,  Melbourne Zoo and Healesville Sanctuary are vital to the species’ survival. 

A survey completed by OEH’s Dave Hunter earlier this year found only nine male Corroboree frogs calling throughout their historic breeding area, with just one nest containing eggs.

Previous releases have already given hope to the species survival, starting in 2010, when 47 eggs were re-introduced, and in 2011, when an additional 244 were re-introduced. Now in 2012, with a further 319 eggs from Melbourne and Healesville, a grand total of 819 eggs will be returned.

Given an average clutch would have about 25 eggs, the project is effectively putting back 33 clutches of eggs back into the wild this year.

Ms Parker hopes for positive results from the release back into the wild, especially as now they are also being reintroduced into areas now free from the fungus called chytrid, which is the main cause the cause for the rapid population decline. 

Taronga and NSW OEH now have successful breeding and re-introduction programs for the Southern Corroboree and Northern Corroboree Frogs, the Booroolong Frog and the Green and Golden Bell Frog, and especially the Golden Spotted Bell Frog, which was previously thought to be extinct.
