Climate shifts and drying conditions across Australia caused a major population crash for koalas approximately 100,000 years ago.
The Frontline Impact
How this affects you
This finding changes how conservationists understand risks to koalas by revealing a long history of climate-driven population decline, which could inform future conservation efforts amidst ongoing human-caused threats. Understanding their historical resilience can aid in making more informed decisions for their future.
