A unique and beautiful mountain-dwelling frog has been bred in captivity and released in the wild—the culmination of years of work by scientists and conservationists.

Dwelling in rainforests at higher elevation in southeast Queensland and northern New South Wales states in Australia, the red and yellow mountain frog was one of 110 priority species the government hoped to save over the next 25 years.

Captive breeding programs are rarer in amphibians than other animals, but the researchers at Southern Cross University have managed it. It required them to replicate much of the frog’s natural habitat; a challenging demand.

Unlike other tadpoles that swim around and feed, the infant red and yellows develop inside their egg sacs and emerge just three millimeters in length—another challenge as they have to be examined via magnifying lenses.

“But to get from egg to adult breeding stage has taken us four years… so it’s a much longer project than we ever envisaged,” said associate professor David Newell, whose colleague, research fellow Liam Bolitho, agreed.

“There’s temperature that we have to try to mimic, the substrate, plants, and also the sound, so we play them frog chorusing calls that we’ve recorded from the rainforest,” Dr. Bolitho told ABC News AU.

“All of these things we have to get perfectly right for them to breed, otherwise it’s not successful.”

In a very secretive place, a solemn yet hopeful ceremony was held as the research team, in partnership with national parks employees and members of the Githabul traditional owners, released 7 red and yellow frogs into a fenced off environment to begin a new chapter in their lives.

Like many animals in Australia, these frogs are threatened by invasive species like feral pigs. These mammals love to wallow in the pools where the frogs lay their eggs. One wrong roll can wipe out a whole generation of tadpoles.

Droughts can also dry out pools and creeks entirely, or shrink them down and thus increase the chance that pigs will smash the eggs.

The NSW National Parks and Wildlife department has undertaken feral pig trapping programs and fenced off several important frog habitats, while the Githabul and other local landowners vigilantly report any pig activity.

It’s a lot of work to save a 3 centimeter-long frog that few Australians will ever see, but it’s a big point of pride for this coalition of scientists and landowners who want to see this magnificent, rainforest ecosystem remain intact.
