Populations of the Spotted Tree Frog have declined to the point that it is now critically endangered.

This species can live up to 10 years, which is quite old for a frog. It lives in the mountain streams of north-eastern Victoria and southern New South Wales. Now it’s only found in a few rocky mountain streams.

Major threats

Like most Australian and international frogs, the Spotted Tree Frog is threatened by the disease, Chytridiomycosis. This is caused by the rapidly spreading Amphibian Chytrid Fungus. Populations of the Spotted Tree Frog are also affected by trout and disturbance to the habitat.

The plan for fighting extinction

Zoos Victoria is playing a major role in the Spotted Tree Frog Recovery Program. We maintain a population in captivity and help monitor the existing populations. This includes re-introducing frogs into the wild.

Zoos Victoria is also researching the role of trout and the Amphibian Chytrid Fungus in the declining numbers.
