Scientists have published findings in the Journal of Pacific Conservation Biology that eight Australian frog species are at ‘high risk’ of becoming extinct over the next twenty years, with four likely to have already become extinct.

According to the study’s author Dr Graeme Gillespie, Chytrid fungal disease, climate change, and invasive species are behind the declining numbers.

Dr Gillespie said, however when we look at the four frog species we believe are extinct, chytrid fungal disease is probably the exclusive factor.
