#ThreatenedThursday: Spotted Tree Frog

#ThreatenedThursday: Spotted Tree Frog

July 28, 2022


SPECIES: Litoria spenceri — Spotted Tree Frog

CLASSIFICATION: Critically endangered


These are the hard facts: with perhaps no more than 12,000 critically endangered Spotted Tree Frogs left in the wild and their population in decline, there’s no doubt that it’s getting harder and harder for the Spotted Tree Frog to continue to survive. Even in good times, this is a species that has always been considered a rare amphibian. The Spotted Tree Frog is found in a handful of rocky mountain streams in north-east Vic and southern NSW. It’s referred to as a sedentary species, so sedentary that most adults will move less than 80m over several years. We’d just call that lazy.


As is the case for most other native frogs, the looming fatal fungal disease, Chytridiomycosis is a constant threat to their survival. The Spotted Tree Frog is also threatened by predation by introduced predatory fish and disturbance to their habitat.
