Koalas are facing steep population declines from habitat loss, disease, vehicle strikes, and climate change impacts. Their welfare as a species and as individuals requires urgent action.
Individual koalas suffer from chlamydial infections causing chronic painful disease, traumatic injuries from vehicles and dogs, and nutritional stress from degraded habitat. Wildlife hospitals treat thousands of koalas annually for these conditions. Habitat protection and wildlife corridor restoration address root causes, while speed reduction and dog management reduce traumatic mortality. Climate change adds pressure by degrading the nutritional quality of eucalyptus leaves on which koalas depend.
