A critically endangered frog could return to a national park near Canberra after conservationists released hundreds of their eggs into parkland.

Known for their distinctive yellow and black stripes, the Northern Corroboree frog is under threat due to a poisonous fungus, damage to its breeding sites and climate change.

Last month, a team from Healesville Sanctuary in Victoria handed over 710 little eggs to a team at Tidbinbilla Nature Reserve in the Australian Capital Territory.

The eggs were released into snow-covered bogland and when the snow starts to melt, the eggs will hatch.

Healesville Sanctuary keeper Meg Whittard said that while mature frogs have been released in the past, this release was especially significant.

“For the first time ever we will be releasing Healesville Sanctuary bred Northern Corroboree frogs as eggs,” Ms Whittard said.

“This is important as we’re not only adding large numbers to the wild population, but also allowing for that development process in their natural habitat.”

Mature, male Northern Corroboree frogs have been heard calling at release sites in the wild, showing that the work of the conservationists is boosting population numbers.

“Since the breeding program started in 2010, we have bred a total of 5276 eggs,” Ms Whittard said.
