Establishing artificial in-situ ponds to allow recruitment of Corroboree Frogs in a chytrid fungus-free environment

The Southern Corroboree Frog (Pseudophryne corroboree) is Australia's most critically endangered frog species, with the decline of this species being attributed to disease caused by infection with the Amphibian Chytrid Fungus (Batrachochytrium dendrobatidis). It is anticipated that this species will be extinct in the wild within the next five to ten years, and hence, the persistence of this species is completely reliant on the successful development of a captive breeding and reintroduced program. The act of maintaining a frog species in the wild using reintroduction techniques has been identified in a Threat Abatement Plan for the Amphibian Chytrid Fungus as being critical for allowing a species to develop greater resistance to, and ultimately co-exist with this pathogen. The aim of this project is to test the potential benefits of reintroducing the eggs of the Southern Corroboree Frog back to the wild by placing them directly into water in artificial pools. This project will involve monitoring the survivorship of the eggs through to a late tadpole stage, and also testing whether the resulting metamorphs are infected with the Amphibian Chytrid Fungus. Given the fact that the Amphibian Chytrid Fungus is now threatening amphibian species on every major continent, the interest and applicability of this project is far reaching.
