This project identified the Australian frog species at greatest risk of extinction, their likelihood of extinctions by 2040 with no improvements to management, and the highest priority management actions needed to prevent extinctions. We found that four of the 26 species may already be extinct. Four more species are more likely than not to become extinct by 2040 unless there are substantial improvements in resourcing, monitoring and management. Chytridiomycosis and climate change are the primary threats to Australian frogs. Priority management actions include developing captive breeding and management programs and establishing wild population refuges; where threat impacts are reduced sufficiently to allow populations to survive.
