Colonisation Fueled Australia's Wildfire Loop
7 Oct
Summary
- Land use changes post-colonisation increased wildfire intensity.
- Indigenous burning practices maintained a managed landscape.
- Dense forests replaced open woodlands, worsening fires.
Post-colonisation land use shifts in south-east Australia initiated a "catastrophic wildfire loop," increasing susceptibility to climate-driven bushfires. Research analyzing 1,000 years of vegetation and fire history in Victoria found that the transition from open woodland to dense forest after 1788 significantly intensified fires.
This change is directly linked to the loss of cultural burning practices and the displacement of the Gunaikurnai people. Prior to colonisation, the landscape was actively managed, but its removal led to increased shrub growth and hotter fires. These intense fires then promoted more eucalypt growth, perpetuating a cycle of increased fire risk.
Scientific evidence now supports the critical value of cultural burning, a low-temperature fire management technique employed by First Nations people. Integrating Indigenous knowledge into contemporary fire management strategies is essential for addressing the worsening wildfire crisis and regaining control over landscapes.
