What has being done to save koala bears already?

The IUCN (International Union for Conservation of Nature) classified Koalas as Lower Risk/Near Threatened in 1996, then Least Concern in 2008. In 2014, Koalas were added to the Vulnerable list, with declining populations. They have not yet been classified as Critically Endangered.

In June 2016, an article noted that the Queensland government admitted that conservation efforts were failing and plan to turn to scientists to salvage remaining healthy populations.
