Almost 700 koalas put down over two years by authorities who say the animals were starving due to overpopulation.
Hundreds of koalas are feared to have burned to death in an out-of-control bushfire on Australia‘s east coast, wildlife authorities said on Wednesday.
A bushfire believed to have been sparked by a lightning strike on Saturday near the town of Port Macquarie some 400km (249 miles) north of Sydney has ravaged an area of more than 2,000 hectares (4,942 acres) with authorities battling to bring it under control.
Wildlife rescuers in northern New South Wales state said they had grave fears for a “very rare” population of hundreds of koalas living in the fire zone.
“The special importance of those koalas is that they are very genetically diverse,” Sue Ashton, president of the Port Macquarie Koala Hospital, told AFP news agency.
Ashton worries that “hundreds” in the known koala breeding area “have perished in the fire”.
“It’s a national tragedy because this koala population is so unique,” she added.
‘Critically endangered’ status sought
Land clearing and development over time has meant a loss of habitat for the tree-dwelling koalas, leading to less connectivity between populations, increased inbreeding and reduced genetic diversity of the marsupial.
More than 70 fires continue to burn across New South Wales, which has been battling severe drought.
Authorities say conditions are easing near Port Macquarie, where aircraft are being used to battle the out-of-control blaze.
“The fire will continue to burn throughout the night, however there are significant resources in the area protecting properties,” New South Wales Rural Fire Service said in their latest update.
Ashton said wildlife volunteers would join firefighters in the area on either Thursday or Friday to assess the scale of loss and begin a rescue operation for the surviving animals.
“What happens to a koala in a fire is that they climb up to the top of the tree and they curl up into a little ball. If the fire goes through quickly and just singes their fur, they are fine the fur will grow back,” she said.
But if the fire intensifies and continues to burn up the tree “they’ll perish”, she added.
“So we won’t really know until we get in there and start to look.”
Last year, a World Wide Fund for Nature (WWF) Australia report said there were probably fewer than 20,000 koalas left in New South Wales and they risked becoming extinct in the state as early as 2050, largely because of “excessive tree-clearing for farming”.
The Australian Koala Foundation estimates there may only be between 43,000 and 100,000 koalas left in the wild across Australia. It argues the classification should be raised to “critically endangered”.
Koalas were thought to number in excess of 10 million before British settlers arrived in 1788.
