Why
Drying conditions across Australia during the last ice age caused koala numbers to fall dramatically and split western koalas from eastern ones.
The Frontline Impact
How this affects you
This finding changes how conservationists understand risks to koalas by revealing their historical resilience to climate-driven bottlenecks and highlighting current human-caused pressures like habitat destruction, disease, and fire.
