Briefings

A 2026 Nature study suggests Australian bush fires intensified post-1901 British colonization due to suppressed Indigenous burning practices, which may have created flammable forest conditions. The evidence indicates a causal link between historical suppression and current fire risk, though the study is a preprint and does not confirm long-term effects.

Key points

• Nature published a preprint on October 7, 2026, proposing that suppressing Indigenous burning practices after 1901 British colonization may have contributed to increased Australian bush fire risk.

Context

This research, published online in Nature on October 7, 2026, investigates historical causes of modern Australian bush fires. It suggests that post-1901 suppression of Indigenous burning practices may have created flammable forest conditions, though the study is a preprint and does not confirm long-term effects.

Limitations

The evidence is limited to a single preprint from Nature, published online on October 7, 2026. The study does not confirm long-term effects of historical suppression on current fire risk, and the authors do not provide further details on the study's methodology or limitations.
