60,000 koalas were impacted by bushfire crisis

More than 60,000 koalas were among the animals impacted by last summer’s bushfire crisis, according to a report commissioned by the World Wide Fund for Nature-Australia.

Impacts include death, injury, trauma, smoke inhalation, heat stress, dehydration, loss of habitat, reduced food supply, increased predation risk, and conflict with other animals after fleeing to unburnt forest.

In July, WWF published an interim version of the study which revealed that nearly 3 billion animals – mammals, birds, reptiles and frogs – were in the path of the devastating bushfires.

That overall estimate is unchanged in the final report, released today, entitled “Impacts of the unprecedented 2019-2020 bushfires on Australian animals”.

About 143 million mammals, 2.46 billion reptiles, 181 million birds, and 51 million frogs occupied areas hit by the fires.

The completed research contains new information including estimates of the impacts on some individual animal species and groupings of species.

It’s estimated that 50 million native rats and mice; nearly 40 million possums and gliders; more than 36 million antechinuses, dunnarts, and other insectivorous marsupials; 5.5 million bettongs, bandicoots, quokkas, and potoroos; 5 million kangaroos and wallabies; 5 million bats; 1.1 million wombats; 114,000 echidnas; 61,000 koalas; 19,000 quolls and Tasmanian devils; and 5,000 dingoes were in the path of the flames.

The fires impacted more than 41,000 koalas on South Australia’s Kangaroo Island, more than 11,000 in Victoria, nearly 8,000 in NSW, and nearly 900 in Queensland.

WWF-Australia CEO Dermot O’Gorman said koalas in NSW and Queensland were in rapid decline before the fires.

“Sixty thousand koalas impacted is a deeply disturbing number for a species already in trouble. That’s why WWF has just announced Koalas Forever – a bold vision to double the number of koalas in eastern Australia by 2050,” he said.

“Koalas Forever includes a trial of seed dispersing drones to create koala corridors and the establishment of a fund to encourage landowners to create koala safe havens.

“It’s part of WWF’s Regenerate Australia plan – the largest and most innovative wildlife and landscape regeneration program in Australia’s history.

“Nearly three billion animals impacted is a number that’s off the charts and shows why a plan of this scale is needed.

“WWF is determined to help restore wildlife and habitats, rejuvenate communities impacted by the bushfires, boost sustainable agriculture and future-proof our country,” Mr O’Gorman said.

The research into how many animals were impacted by the fires was managed by Dr Lily Van Eeden and overseen by Professor Chris Dickman, both from the University of Sydney.

Their recommendations include implementing mapping and monitoring of plants and animals in bioregions most at risk in future fires, and developing strategies to protect these areas during fires.

“We didn’t have a lot of data for some animals. More research is needed on how many animals are out there and their ability to survive different levels of fire intensity. We need to understand this to protect species more effectively,” said Dr Van Eeden.

“People have been shocked by our research and have said to me ‘we can’t allow catastrophes of this magnitude to continue into the future’” said Professor Dickman, who is also a WWF-Australia board member.

“With long term monitoring we would be in a much better position to know where and when to act and what resources are needed to save at risk species,” he said.
