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.
