While Australia's devastating wildfires killed or displaced over 60,000 koalas, fire is not the only or even the most serious long-term threat they face. A widespread bacterial infection called chlamydia affects over 50% of koala populations in northern Australia, causing permanent infertility and quietly crippling their ability to recover. In this video, we explore how disease, habitat fragmentation, and genetic isolation work together to drive the silent decline of koalas. What you will learn:The Chlamydia Crisis: Why bacterial infections cause widespread infertility and threaten koala survival beyond natural disasters. The Fragmentation Trap: How roads and cities split eucalyptus forests, trapping populations and speeding up disease spread. The Silent Extinction Risk: Why long-term extinction is driven by a combination of disease, isolation, and habitat loss. Join the discussion: Have you heard before about a species endangered because of disease rather than hunting or fires?
