NSW Koalas Higher Than Thought: New Survey Tech Used

A recent comprehensive survey in New South Wales indicates that koala populations may be substantially higher than previously believed. The NSW government's statewide survey estimates approximately 274,000 koalas inhabit the state. This updated figure was achieved through the deployment of advanced tools, such as heat-detecting drones and acoustic recorders, across over 1,000 locations.

It is crucial to understand that this higher estimate does not signify a population increase but rather reflects improved survey methodologies and extensive data collection. Previous estimates for NSW varied dramatically, ranging from 15,000 to 30,000 koalas. The current findings are part of a broader national effort by the CSIRO, which estimates between 729,000 and 918,000 koalas nationwide.

Despite the revised numbers, experts emphasize that koalas in NSW remain endangered. They continue to face critical threats, including severe habitat loss, disease, vehicle collisions, and the escalating impacts of climate change. Conservation efforts, such as the proposed Great Koala National Park, are deemed essential to protect the species and guide future conservation decisions.
