The Australian bushfires which have ravaged the country since September are having a devastating impact on wildlife populations.
Ecologists from the University of Sydney estimate 480 million mammals, birds and reptiles have died due to the fires. Among these, 8000 koalas are believed to have burnt to death - nearly one third of the entire koala population in New South Wales (NSW), news.com.au reports.
Koala numbers are believed to have declined across a number of states, but the figures remain unclear.
While speaking to the NSW parliament in December, an ecologist expressed fears that the number of koala deaths may never be known.
"The fires have burned so hot and so fast that there has been significant mortality of animals in the trees, but there is such a big area now that is still on fire and still burning that we will probably never find the bodies," Nature Conservation Council ecologist Mark Graham said.
Science for Wildlife executive director Dr Kellie Leigh also told the hearing that koala populations threatened by bushfires have no resources or planning in place to save them.
"We're getting a lot of lessons out of this and it's just showing how unprepared we are," Dr Leigh said.
"There's no procedures or protocols in place - even wildlife carers don't have protocols for when they can go in after fire."
The Sydney Morning Herald reported that experts believe human intervention is needed to repopulate sensitive species that would otherwise be wiped out locally.
Wildlife Rescue South Coast secretary Jenny Packwood said there is a "starvation event" after flying foxes flew south in spring after fires destroyed their habitat.
"Mothers are abandoning babies at two weeks after birth because there is no food for them. We've picked them up out of local colonies," she said.
"Last week we had 300 come in and we've been flat out feeding since then. We had to fly some of them to the North Coast, to carer groups up there."
