The large-scale ‘Black Summer’ fires of 2019/2020 burned through 1.8 M ha of forest and woodland across eastern Australia. The fires began during Australia’s hottest and driest year on record and burned an unprecedented extent of rainforest. These rainforests support a number of endemic, range-restricted amphibians, including several species of mountain frog (Philoria species). This project aimed to assess the impact of the fires on three species of Philoria: the mountain frog, Richmond mountain frog, and Loveridge’s mountain frog.
