Spotted Tree Frogs are the ‘couch potatoes’ of the frog world. They are very sedentary, and most move less than 80 meters over several years.
These frogs have lots of brothers and sisters! Parents lay between 50-1000 eggs during each breeding season. Eggs are buried beneath boulders in fast-flowing streams.
Spotted Tree Frogs play a critical role in their local ecosystem by keeping the streams clean and healthy through feeding on the algae.
Where can you find them?
The spotted tree frogs' natural habitat used to be the mountain streams of north-eastern Victoria and southern New South Wales. However, they are now largely extinct in these areas and are only found in a few rocky mountain streams.
Their main threat is from a deadly infectious disease, Chytridiomycosis, which also affects other frogs. Other threats are from predators such as Redfin, Carp and Trout, and from habitat loss and damage, including weed invasion. Their populations also declined due to the Black Summer bushfires (2019-2020). There is currently a recovery plan in place which aims to prevent the spread of Chytridiomycosis and develop effective captive breeding regimes.
