The Spotted Tree Frog, Litoria spenceri, is a mountain stream frog species from north-eastern Victoria and southern New South Wales. The Spotted Tree Frog is listed as Critically Endangered: like many other Australian and international amphibians, populations have declined in recent years.
Due to predation by trout and habitat disturbance, Spotted Tree Frogs now only occur in a few reaches of rocky mountain streams in just 13 river systems. These remaining populations are now threatened by Chytridiomycosis (a disease caused by Amphibian Chytrid Fungus).
Zoos Victoria became involved in the Spotted Tree Frog Recovery Program in 1991. Captive breeding is an increasingly important element of the coordinated Recovery Program.
