Ten frog species disappeared from the upland rainforests of the Wet Tropics and Eungella during outbreaks of amphibian chytrid fungus (Batrachochytrium dendrobatidis) in the late 1980s and early 1990s, representing 25% of the frogs endemic to the Wet Tropics and all of the Eungella endemics. Five of these species occurred only in the uplands and have been presumed extinct because no individuals have been found despite intensive searches. This represents a significant loss of endemic species diversity, particularly in the Wet Tropics World Heritage Area.
