Australia is the most fire-prone country in the world, with fire services responding to between 45,000 and 60,000 bushfires each year. The country experienced its worst fire season in history during the summer of 2019-2020, with over 29 million acres of forest and woodland burned, 33 people killed, and 3,094 homes lost. The fires also had a devastating impact on wildlife, with nearly 3 billion animals killed or displaced, including 143 million mammals, 180 million birds, 51 million frogs, and 2.5 billion reptiles. The bushfires were preceded by months of drought and coincided with Australia's hottest month on record, making the fires even more destructive.

What You'll Learn
The impact on wildlife and biodiversity
The 2019-2020 Australian bushfires had a devastating impact on the country's wildlife and biodiversity. Nearly 3 billion animals were killed or displaced by the fires, including an estimated 143 million mammals, 180 million birds, 51 million frogs, and 2.5 billion reptiles. The fires destroyed the habitats of these animals, leaving them vulnerable to starvation, dehydration, and predation by feral animals, particularly cats.
The bushfires also had a significant impact on endangered species, such as the koala, which was pushed to the brink of extinction. Other threatened species include the Kangaroo Island dunnart, for which artificial shelters had to be provided, and the brush-tailed rock-wallaby. Conservationists have called for better monitoring of biodiversity and threatened species protection in the wake of the bushfires, as Australia was already losing biodiversity at an alarming rate and had one of the highest rates of extinction globally.
The bushfires also affected the distribution of ecosystems and delayed vegetation recovery. For example, the fires burned critical winter habitats for the gray-headed flying fox, a vulnerable species of forest pollinators. The largest effects on plants and animals were observed in areas with frequent or recent past fires and within extensively burnt areas.
The impact of the bushfires on wildlife and biodiversity was immense and will likely be felt for years to come. The WWF Australia's Wildlife and Nature Recovery Fund raised over $50 million for wildlife and nature recovery, and initiatives like Eyes on Recovery, which uses motion-activated cameras to monitor the recovery of Australian wildlife, have been launched to help mitigate the impacts of the bushfires and prevent such catastrophic events in the future.

Human death toll and displacement
Australia's bushfires during the summer of 2019-2020 were unprecedented and catastrophic. The fires killed 33 people and burned some 42 million acres (17 million hectares) of land in New South Wales, Victoria, Queensland, the Australian Capital Territory, Western Australia, and South Australia. The New South Wales and Victoria bushfires in 2019 and 2020 ravaged millions of hectares of vegetation and killed or displaced 3 billion animals. This includes an estimated 143 million mammals, 180 million birds, 51 million frogs, and 2.5 billion reptiles.
The deadliest series of fires in Australian history, referred to as Black Saturday, occurred on February 7, 2009. These fires caused 173 deaths, destroyed over 2,000 homes, and left more than 7,500 people homeless.
The 2019-2020 bushfires had a severe impact on the human population, with 3,094 homes lost and many people displaced. The fires also had a significant impact on the wildlife and forests, with over 29 million acres of forest and woodlands burned. This pushed many threatened species, including the koala, to the brink of extinction. The Australian government has since implemented controlled burns to reduce the risk of catastrophic bushfires and protect and encourage biodiversity.
The bushfires also had a significant impact on the mental health and well-being of Australians. The smoke produced by the fires created health risks for those not directly affected by the flames, and the destruction of herds of livestock impacted the livelihoods of those who relied on them. The Australian bushfires also highlighted the need for better monitoring of biodiversity and threatened species protection. Conservationists have linked Australia's limited monitoring of its wildlife to funding cuts for environment programs.

Property damage
Bushfires in Australia have caused significant property damage over the years, with increasing population and urban spread into bushland, resulting in higher damage to properties. The 2019-2020 bushfire season in Australia was unprecedented and catastrophic, with over 29 million acres of forest and woodlands burned, and a devastating impact on wildlife and the environment.
During this season, over 18 million hectares were burned, destroying more than 5,900 buildings, including 2,800 homes. The 2019-2020 bushfires emitted 400 megatonnes of carbon dioxide into the atmosphere, according to the Copernicus monitoring programme. This is a significant contribution to Australia's annual carbon dioxide emissions and will have long-lasting effects on the environment.
The most destructive fires in Australia's history, known as "Black Saturday" in 2009, resulted in the loss of 3,500 buildings, including 2,029 houses, and the displacement of 7,562 people. These fires, which burned across Victoria, were preceded by extreme high temperatures, low humidity, and strong winds, creating ideal conditions for the rapid spread of fire.
The 1967 Tasmanian fire season, Australia's fourth most deadly, destroyed almost 1,300 homes. The worst recorded bushfire in Australia occurred in 1974-1975, when 15% of Australia's land mass suffered extensive fire damage. More recently, the 2003 Canberra fire disaster cost insurers $257 million, and the 2004 and 2007 Victorian bushfires caused over $900 million in damage, including destruction to forests and property, and suppression costs.
The impact of these bushfires extends beyond the immediate destruction of homes and buildings. The loss of trees and foliage leads to increased runoff during rainy periods, causing extensive soil erosion and silt and ash flow, which can damage water storage facilities and stream gauging stations. Additionally, the smoke from bushfires can travel great distances, affecting air quality in major cities across Australia and even reaching other countries. The social and economic ramifications of these disasters are far-reaching, with displacement of people, trauma, loss of possessions, and increased insurance costs and government budgets.

Climate change and the future
Australia's 2019-2020 bushfires were unprecedented and catastrophic, with over 29 million acres of forest and woodland burned. The fires had a devastating impact on wildlife, with nearly 3 billion animals killed or displaced, including an estimated 143 million mammals, 180 million birds, 51 million frogs, and 2.5 billion reptiles. The bushfires also resulted in significant human casualties and property damage, with 33 lives lost and 3,094 homes destroyed.
The scale of the bushfire disaster has raised concerns about the future of Australia's unique and diverse ecosystems in the face of climate change. As Professor Mike Clarke of La Trobe University, Melbourne, described: "When you walk into a forest that's been burnt this badly, the overwhelming thing that hits you is the silence. No birdsong. No rustling of leaves. Silence."
The recovery of Australia's biodiversity will be a long and challenging process, requiring human intervention and favourable weather conditions. Experts have identified the need for concrete measures to combat climate change and mitigate the impact of future bushfires. This includes a proposed moratorium on logging, improved pest control of feral animals, and the implementation of weed removal initiatives.
Additionally, there has been a call for a return to Indigenous burning practices, known as "firestick farming" or "cultural burns." These practices involve controlled burns to reduce the fuel available to natural bushfires and protect biodiversity. Indigenous Australians have utilized these techniques for thousands of years, and their value in preventing catastrophic bushfires is now recognized by the Australian government.
The bushfires in Australia serve as a stark reminder of the urgent need to address climate change and develop sustainable practices to protect our planet's fragile ecosystems and biodiversity. By learning from the past and implementing proactive measures, we can work towards a future where both human and animal populations can coexist and thrive in harmony with nature.

Recovery and conservation efforts
The Australian bushfires of 2019-2020 were unprecedented in scale and destruction, with over 24 million acres of land burned and nearly 3 billion animals killed or displaced. The Australian government, along with various organisations and individuals, has undertaken recovery and conservation efforts to protect wildlife and support long-term restoration.
The Australian Government established the National Bushfire Recovery Agency to coordinate a national response to rebuild communities and livelihoods. The government committed an initial $50 million for immediate wildlife protection and long-term restoration, with $25 million going towards an emergency intervention fund and the remaining $25 million supporting wildlife rescue, zoos, and conservation groups. Additionally, up to $7 million was allocated for Natural Resource Management groups to carry out emergency interventions, control feral predators and weeds, and implement habitat protection measures. The government also provided funding for wildlife rescue and protection services, as well as for Greening Australia's efforts to increase the supply of seed and native plants for revegetation.
Indigenous rangers have played a crucial role in bushfire recovery efforts, particularly in the Mid North Coast region of New South Wales through the Taree Indigenous Development and Employment (TIDE) Aboriginal Bushfire Recovery Rangers program. They have improved recovery outcomes for wildlife and habitats through pest and weed control, tree planting, and the installation of nest boxes, while also gaining essential training in natural resource management.
Conservation groups have also been active in recovery efforts. Conservation Volunteers Australia has a volunteer mobilisation project, and Greening Australia has Project Phoenix, a 10-year strategy for the native seed sector. The WWF and Conservation International launched Eyes on Recovery, an initiative using over 1,100 motion-activated cameras to monitor wildlife recovery, capturing over 7 million photos cataloged using Wildlife Insights, an AI-powered platform. This technology has helped identify over 150 Australian species, providing valuable data for conservation efforts and understanding nature's resilience.
The University of Sydney and other universities have contributed to the study of surviving flora and fauna, with the University of Sydney conducting over 320 individual surveys to assess the impact on reptile populations. The Trust for Nature has also supported the ecological recovery of habitats for threatened species and vegetation. These collective efforts aim to boost wildlife recovery, restore habitats, and increase resilience in the face of climate change and natural disasters.

Frequently asked questions
While I could not find an exact number, it is likely that thousands of people were displaced by the Australian bushfires of 2019-2020, considering that 3,094 homes were lost.
The bushfires killed or displaced nearly 3 billion animals, including 143 million mammals, 180 million birds, 51 million frogs, and 2.5 billion reptiles. The fires also destroyed millions of hectares of vegetation, pushing many threatened species, including the koala, to the brink of extinction.
Australia is the most fire-prone country in the world, and bushfires are frequent occurrences due to the continent's hot and dry climate. More than 90% of bushfires are started by people, either accidentally or deliberately, and the most common natural cause is lightning. Climate change has also been identified as a contributing factor, with scientists warning that adding more greenhouse gases to the atmosphere would increase bushfire risk.
