Several factors are considered to be contributing to the decline of the Spotted Tree Frog.  Introduced trout occur in all catchments it occupies and they prey on their tadpoles.  Habitat disturbance from forest management, road works, recreational activities in mountain catchments, such as trail bikes and 4WD vehicles, all contribute to increased erosion, sedimentation of streams, damage to riparian habitat and weed invasion. These disturbances may also have been exacerbated by the extensive bushfires in the region in 2003 and 2006.

A new amphibian disease, Chytridiomycosis (referred to as Chytrid Fungus), is also believed to be a contributing factor to the Spotted Tree Frog's decline. The Chytrid Fungus infects the frogs’ skin, causing damage to the keratin layer, causing death in many species. This disease is thought to be responsible for many amphibian declines in Australia and around the world in recent years.
