LIFE OF CUTE KOALA 03

Koala numbers plummeted in the late 19th and early 20th century from hunting for their fur. Now they face serious threats from habitat loss. Land clearing, logging, and bushfires—especially the devastating 2019-2020 season—have destroyed much of the forest they live in. Koalas need a lot of space—about a hundred trees per animal—a pressing problem as Australia's woodlands continue to shrink.

Koalas are listed as vulnerable by the International Union for the Conservation of Nature, which has named the species one of 10 animals most vulnerable to climate change. Increasing carbon dioxide in the atmosphere is decreasing the nutritional quality of eucalyptus leaves (which is already quite low) and causing longer, more intense droughts and wildfires. In response to drought, koalas are forced to stop napping and come down from the trees to find water, spending precious energy and putting them at a higher risk of predation.

Predators include dingoes and large owls. They’re also at risk of getting hit by cars and attacked by dogs. Chlamydia is widespread in some koala populations and can cause blindness, infertility, and sometimes death.
