Research in Brief
The prediction by Professor Chris Dickman that more than 1 billion (and later 3 billion) animals were killed in the 2019–20 bushfires helped focus the world’s attention on the plight of Australia’s wildlife. Yet these predictions were admittedly “back of the envelope”, based on research from the mid- 2000s that used animal density estimates to predict the mortality of birds, reptiles and mammals due to land clearing. However, such mortality estimates may not be directly applicable to fire-induced mortality because some animals can survive fires, depending on their traits, the environment, availability of refuge habitat and the fire’s intensity. This project will review the literature on wildlife mortality during fire and help provide a framework for obtaining rapid mortality estimates during future fires in Australia and around the world.
Why is the research needed?
Billions of animals were caught in the path of the 2019–20 bushfires, yet we have little understanding of what proportion of these animals died during and following the fires. Such an understanding is critical to estimating the overall impacts of the fires on wildlife, including threatened species, and the likely time to recovery. This project will help fill this gap by systematically reviewing the literature on fireinduced wildlife mortality.
How will the research help?
This project will highlight the scale of impacts on vertebrate animals during the 2019–20 bushfire season, and strongly complements NESP Threatened Species Recovery Hub Project 8.3.2. We will review data on fire-induced wildlife mortality to help enumerate the scale of fire-induced wildlife mortality and reveal the species that have likely suffered the largest population declines due to the fires. It will thereby refine understanding of which species are in most urgent need of on-ground conservation actions, help provide more resolution for assessments of changes in conservation status, and provide a framework for obtaining rapid mortality estimates during future fires in Australia and around the world.
