Climate change



Climate change is likely to affect the amount of nutrients that koalas obtain from their main food source, Eucalyptus.

Elevated carbon dioxide levels increase plant growth but reduce the protein levels and increase the amount of tannins in the leaves, causing possible malnutrition and starvation if the koalas are not able to meet their nutritional demands.

Droughts and bushfires, to which the koala is particularly vulnerable, are also increasing in frequency and severity due to climate change.
