Associate Professor Grant Hamilton has joined with Noosa and District Landcare to launch a project that will use technology and artificial intelligence to create a “census” of animals that survived the bushfires.
“We know that the devastating bushfires have had a terrible impact on wildlife, but in order to help protect those which survived the terrible disaster we first need to identify the populations of animals that are still in fire affected areas,” Professor Hamilton said.
Last year, Professor Hamilton co-authored a study with PhD student Evangeline Corcoran and Dr Simon Denman from QUT, and John Hanger and Bree Wilson from Endeavour Veterinary Ecology, that was published in Nature journal Scientific Reports, that detailed a technique for locating koalas using drones that can detect heat signatures.
The researchers created an algorithm that was designed to identify the heat signatures of koalas, which can be very difficult to spot from ground level.
Noosa and District Landcare acting general manager Rachel Lyons said the recent bushfires affected koala habitat in the Noosa region at Peregian Springs, Weyba Downs, Doonan and Cooroibah.
“The main burn zones were very intense with full canopy fires, flanking areas and back burn sites varied in intensity,” Ms Lyons said.
“Koalas were unlikely to have survived the canopy fire areas and we have held concerns about the survival of koalas in the less intense sites.
“Koalas have been rescued within the areas post-fire as a result of concerns for health and food availability.”
Professor Hamilton said the Sunshine Coast research project was the first in what could be a wider study of koala populations in bushfire affected areas. Professor Hamilton is currently in discussions with other animal welfare groups to carry out drone surveys for koalas in other areas.
“We are also working on ways to extend our algorithm to automatically detect other species likely to be found in the areas,” Professor Hamilton said.
“Last year, we were able to show that our system for detecting koalas was more accurate than using expert observers.
“Another advantage of using drones to spot animals from the air is that we can cover areas much quicker than people on foot can conduct a search, and we can cover areas that are too inaccessible for spotters on the ground.”
The researchers will begin their drone survey of the Noosa region fire areas as soon as cooler morning temperatures better allow for the heat sensing drone cameras to detect koalas by their heat signatures.
Professor Hamilton’s work in this area has recently been profiled as part of DJI’s Drones for Good project.
