When devastating bushfires ripped through New South Wales, displacing and injuring koalas, ANU became a temporary home for many of these beloved creatures.
Now, they are being released back to their homes, and thanks to the generosity of donors, researchers can continue working to understand the impact of bushfires and climate change on koalas and their habitat.
Thin, dehydrated and starved koalas arrived at ANU in January 2020 for much needed medical attention. Thanks to the generosity of our donors the koalas received the special care they needed to return to their homes. Researchers were able to release two koalas back into their habitat at Two Thumbs Wild Sanctuary in June.
While Hamish and Bear were ready to return home, the work of ANU researchers must continue to ensure these beloved creatures thrive. With much of the landscape still burnt, it is not yet clear how the koalas with adapt to this change. The pair have been fitted with GPS collars so researchers can understand how they are using their still recovering habitat.
A partnership with the Minderoo Foundation through a donation of $257,000 will assist researchers to examine how kolas recover after fire and how fire impacts their habitat and dietary requirements. Dr Kara Youngentob said the research will help determine when koalas in care could be returned to their habitats.
"We will examine how fire affects the nutritional quality of koala habitats and eucalypt trees after a fire. Our research is critical for the development of strategies that minimise bushfire impacts of wildlife".
The ANU research project will examine how fire impacts eucalypt leaf chemistry and nutrition for koalas. The researchers will also determine whether koalas can feed on epicormic growth - buds that lie dormant under the bark of a tree and emerge after fire.
The research builds on care given to koalas directly affected by fires at ANU earlier this year, with the initial work also made possible by a generous $100,000 donation from Two Thumbs Wildlife Sanctuary - which was burnt down in this year's catastrophic fires.
The project is also supported by the NSW Government Department of Planning, Industry and Environment under the NSW Koala Strategy and the Australian Government Wildlife and Habitat Bushfire Recovery Program.
"We've already discovered koalas can digest new, epicormic growth from some of the trees that they usually eat," ANU co-researcher Dr Karen Ford said.
"This breakthrough has allowed us to return the first two koalas in our care back into the wild at Two Thumbs Wildlife Sanctuary in late June. A lot of our initial conservation work and ongoing research was made possible by a $100,000 donation from Two Thumbs Wildlife Sanctuary and its trustee, James Fitzgerald.
"What's also really touching about James' generous gift is that it has been made in the memory of Ian McBeth, Paul Clyde Hudson and Rick A DeMorgan Jr - the three US firefighters who lost their lives fighting fires near the Two Thumbs Wildlife Sanctuary earlier this year.
"We are really excited that Minderoo Foundation are now also joining these efforts and hold great hope for the future."
This research is an important part of protecting an Australian icon, and the support from donors is contributing to positive outcomes for koala survival.
"With koalas facing the very real threats of localised extinctions and widespread habitat loss, as well as reeling from the unprecedented fires we've suffered this season in Australia, this is an investment in the long-term survival of one of this nation's and the world's most iconic animals" Dr Youngentob said.
"This is a major boost for koala conservation and management."
In addition to examining koalas' diets, the ANU researchers will track the fate of koalas from fire-affected areas and those that were not taken into care in nearby burnt and unburnt areas. In addition, they will investigate a potential rapid method to provide useful koala heath information from their droppings.
