Mapping the wilderness

In this episode of Late Night Live, host David Ma speaks with Professor James Watson, a conservation scientist at the University of Queensland, about the first comprehensive map of Australian wildernesses in 40 years. The map, created using 16 data sources including satellite imagery, road networks, and census data at 100-meter resolution, reveals that Australia has lost at least 20% of its wilderness since the last assessment, with significant degradation in regions like Cape York, the Pilbara, and northeast Tasmania due to mining, logging, and infrastructure development. Despite this, 30% of the continent remains largely untouched by industrial activity—areas vital for ecological resilience amid climate change. Watson emphasizes that while feral predators like cats and foxes have disrupted native ecosystems, these regions still serve as critical refuges for biodiversity and ecological function. The map is positioned as a key tool for achieving Australia’s 30 by 30 conservation target—protecting 30% of the country by 2030—especially through Indigenous Protected Areas. However, Watson expresses cautious skepticism about political will, noting that while government commitments exist, funding and enforcement lag behind ambition, and profitable development often overrides environmental protection. The episode underscores a global crisis: wilderness loss is accelerating worldwide, not just in Australia, with remote areas no longer safe from human impact due to technological advances. Watson warns that once industrial activity begins in a wilderness area, restoration is nearly impossible. Yet, he highlights rare victories—such as Indigenous-led rejections of mining projects and the Brisbane Toon To Harbour development decision—as signs that change is possible. The map will be publicly available from Thursday via the Earth System Science Data Journal and the University of Queensland, offering a transparent, science-based roadmap for conservation. The conversation ends on a note of urgency and cautious hope: the data is now in place, but the real challenge lies in translating policy promises into on-the-ground action.
