KOALA

Did you know there could be koalas or other threatened wildlife living near you? Discover what animals need protection in your local area using 

WWF-Australia’s ‘My Backyard’ tool, and find out how well they’re being cared for.

The koala is one of the world’s most iconic animal species – right up there with the panda, tiger, elephant, dolphin, and polar bear. And they're found nowhere else in the world but Australia!

Our much-loved koalas, with their stocky, tailless body, big head with round, fluffy ears and large, oval-shaped nose, are instantly recognisable as a symbol of Australian nature.

Threats

Tree-clearing

Sadly, koala trees and habitats are being destroyed or fragmented because of landclearing for agriculture and urban development. Not only does this lead to fewer trees for koalas to eat and sleep in, it also means koalas must spend more time on the ground when moving from tree to tree. Once down there, they are much more vulnerable to being hit by cars and attacked by dogs, while elevated levels of stress make them prone to sickness and diseases like Chlamydia.

Climate change

Changing weather patterns and a warming climate are putting pressure on many of Australia’s ecosystems and animals. Drier weather means the eucalyptus leaves koalas rely on contain less moisture. Prolonged droughts and extremely high temperatures, like heatwaves, can also make koalas very sick and dehydrated, as well as increase the risk and severity of bushfires during summer.

Thankfully, there is much we can do to save the koala and the many other species that inhabit the Australian bush.
