Chris Dickman, a fellow of the Australian Academy of Science from the University of Sydney, estimated on 8 January 2020 that more than one billion animals were killed by bushfires in Australia; while more than 800 million animals perished in New South Wales.The estimate was based on a 2007 World Wide Fund for Nature (WWF) report on impacts of land clearing on Australian wildlife in New South Wales that provided estimates of mammal, bird and reptile population density in the region.
