Koala Clancy Foundation, Media Release, Staughton Vale, 30 April 2026
Koala monitoring on a tree planting site beside the Moorabool River, Victoria has shown an unexpected growth in koala observations in just one year.
More than 11,300 koala trees and shrubs were planted on the site by Koala Clancy Foundation and the International Fund for Animal Welfare (IFAW) in the winter of 2023 and 2024. In November after each planting, audio recorders were set up to monitor the koala population.
Monitoring koalas by audio recorders is a widely-used and non-invasive method that records adult males calling in breeding season. Female koalas do vocalise too, but less often.
Koala tree planter Janine Duffy said that not many koalas were expected in the first year while the trees were still small.
“In the first year we recorded four koala calls – not many, but a good start, and showed that the site had potential to be good for koalas,” said Janine.
“We were blown away to hear that koala calls had tripled in the second year of monitoring,” she said.
“We really hoped to find an increase in koalas using the property as a result of our revegetation, but we expected it would take more than just one year!”
“Several different males were heard on the recordings, and there was even a short recording of a female and male mating.”
IFAW head of programs Josey Sharrad said the project was an important one, and one close to her heart.
“Koalas across Australia are disappearing as their homes are cleared, so hearing their calls return to this landscape after just a few years is incredibly powerful,” Ms Sharrad said.
“These trees are still young, yet koalas are already using the site. It shows just how desperately koalas need safe habitat, and how quickly they will respond when we give it back to them.”
”This project proves that restoration works. Knowing that something we planted with our own hands is already helping koalas survive fills me with hope for their future.”
