The NSW National Parks and Wildlife Service (NPWS) has released 50 juvenile Green and Golden Bell Frogs and a further 500 tadpoles into wetlands at Pambula to bolster an existing population that began from 6,000 tadpoles released over the past six years.

The release is part of a program to re-establish a population of the endangered Green and Golden Bell Frog begun over a decade ago by the Bega Environment Network in conjunction with frog breeder Peter Johnson.

NPWS Ranger, George Malolakis, who has managed the program since 2004 says the release of new tadpoles and frogs will be an important step in their reestablishment.

"This is the third release at the same site and one which we think is critical to the success of this program. This release is designed to bolster the numbers of the existing population with the aim of achieving a self sustaining new wild population," Mr Malolakis said.

"We are very encouraged by the fact that the frogs that exist today at the wetlands are the result of earlier releases.

"Considering that they managed to come through one of the worst droughts in living memory that's quite a result.

"The Green and Golden Bell Frog was once an abundant species with a range that extended from the Queensland border to Victoria. Today it is listed as endangered because the species crashed in the 70s, probably due to the arrival of Chytrid fungus which has been implicated in the decline of numerous frog species world wide.

"The Green and Golden Bell Frog in NSW has been reduced to a handful of sites and re-establishing a new colony at Pambula is very important if we are to prevent this species from becoming extinct.

"This latest release has been possible through funding provided under a Departmental initiative called ‘Find it and Fix it' in which funding is provided for special projects that can achieve a significant conservation outcome.

"Funds from this initiative have been used to test the release animals for diseases to ensure that chytrid fungus, a deadly frog pathogen, is not inadvertently introduced to the wetlands.

"It has also helped maintain the breeding population housed by frog breeder, Peter Johnson, who has been intimately involved in this project for many years by providing frogs and tadpoles. Without Mr Johnson's involvement this project could not have been possible as he has maintained a population of Green and Golden Bell Frogs collected from this Far South Coast area prior to collapse of the local population, making the release frogs genetically suitable for release in this area." Mr Malolakis said.
