Koalas face multiple intersecting welfare threats including chlamydia disease, habitat loss, road casualties, and dog attacks. Their status as an iconic species masks a genuine welfare emergency.
Chlamydia-affected koalas experience chronic pain from urinary tract infections, conjunctivitis causing progressive blindness, and reproductive disease preventing breeding. Animals with advanced chlamydia often cannot feed, thermoregulate, or reproduce — declining over months to years. Bushfire-affected koalas with burns to paws, face, and torso require intensive veterinary care and face high mortality from secondary infections. Dog attacks cause traumatic injuries including internal bleeding and broken bones. Road casualties cause traumatic impact deaths with significant survivor proportion dying from delayed injuries. The combination of chronic disease, acute trauma, and habitat loss creates a multi-factor welfare crisis in an iconic but genuinely endangered species.
