研究人员与古尼库尔奈土地和水域原住民公司合作，重建了维多利亚州克罗金戈隆国家公园普格哈古拉湖周围1000年来的植被和火灾历史，发现1788年殖民化后该地区的火灾格局发生了根本性改变1。这项研究表明，殖民化导致该地区从开放林地转变为密集森林，土地利用方式的转变与文化烧烤实践的丧失相伴随，最终引发了火灾强度的加剧1。
研究发现，这种变化造成了一个灾难性的野火循环，使东南澳大利亚更容易受到气候驱动的野火影响1。
Researchers working with the Gunaikurnai Land and Waters Aboriginal Corporation have reconstructed one thousand years of vegetation and fire history surrounding Purghagoolah Lake in Croajingolong National Park, Victoria, revealing how colonisation fundamentally altered the landscape's fire dynamics.1 The analysis found that following 1788, the transition from open woodland to dense forest corresponded with the abandonment of cultural burning practices, creating what the study describes as a "catastrophic wildfire loop" that has increased susceptibility to climate-driven bushfires across southeastern Australia.1
The shift in land use following European settlement directly contributed to more intense fire events in the region.1 The loss of traditional fire management—a practice maintained by Indigenous peoples for centuries—allowed vegetation to accumulate and forests to densify, fundamentally changing how fire behaves across the landscape and leaving communities in the southeast increasingly exposed to severe bushfire risk.1
