Wildlife ravaged by Australia fires could take decades to recover

The bushfires raging across Australia have had a devastating impact on the country’s unique flora and fauna, with some estimates putting the death toll at nearly half a billion animals in one state alone, and experts believe it could take decades for wildlife to recover.

Unprecedented temperatures across the continent have made this season’s fires particularly deadly, killing at least 20 people and bringing apocalyptic scenes to an area roughly twice the size of Belgium.

The crisis has focused attention on climate change, which scientists say is creating a longer and more intense bushfire season, and the Australian government has faced widespread criticism over its response and wider environmental policy

Harrowing footage of desperate koalas drinking from water bottles handed to them by rescuers and kangaroos standing helpless in fire-ravaged towns and charred forests have shocked people across the world

There is some hope, however, as experts believe scorched forests can recover in time, and decimated populations of koalas, kangaroos and other badly affected species may be able to return

A University of Sydney study estimates that 480 million animals have been killed in just the state of New South Wales (NSW) since September 2019, and according to a statement released  the authors said the “highly conservative” mortality calculations could mean the toll could be “substantially higher”

In order to reach the figure, the researchers cross-referenced estimates of mammal population density in NSW with areas of vegetation known to have been scorched to work out the death toll, which includes mammals, birds and reptiles, but not insects, bats or frogs.

“The true loss of animal life is likely to be much higher than 480 million,” the statement said.

NSW’s wildlife is seriously threatened and under increasing pressure from a range of threats, including land clearing, exotic pests and climate change.”

Professor Andrew Beattie from Macquarie University near Sydney told AFP he believes the death toll of animals nationwide could be in the billions, “if you think of mammals, and birds, and reptiles, amphibians and say the larger insects such as butterflies

We can be pretty sure that in large parts of these very expansive fires, most of the wildlife will be dead,” the emeritus professor from the department of biological sciences said

The flora and fauna will be gone, and that includes the smaller animals which form the food chain for the bigger ones, which people often don’t think about

Koala populations have been hit particularly hard because they live in trees, feed only on certain types of eucalypts and cannot move quick enough away from the flames

Even before this year’s bushfire crisis, numbers in NSW and Queensland had already dropped by 42 percent between 1990 and 2010, according to the federal threatened species scientific committee
