What This Study Tells Us About Controlled Burning and Wildfire Risk

Paper: Fuel reduction burning reduces wildfire severity during extreme fire events in south-eastern Australia

An Australian study has looked closely at how effective fuel reduction burning is in reducing wildfire severity, particularly under extreme fire weather.

Researchers found that in areas where controlled burns had taken place, wildfire severity was noticeably lower for up to 2–3 years in shrublands and 3–5 years in forests, compared with areas that hadn’t been treated.

The greatest benefits were seen within the first 18 months, when reduced fuel loads made fires less likely to start or spread, regardless of weather conditions.

The researchers conclude that regular, well-planned burning close to vulnerable assets can help limit wildfire spread, but its benefits are temporary and depend on maintaining consistent fuel management over time.

Takeaway

This study reinforces the importance of maintaining regular, controlled burning as part of long-term wildfire management - reducing risk, protecting communities, and preserving the land.
