## WHAT THE EVIDENCE SAYS

Editorial interpretation of evidence discussed in this edition.

## WHY IT MATTERS / OUR READ

Deep time is producing another challenge to simple fire narratives. New Antarctic sediment evidence suggests early Sphagnum peatlands and wildfire co-evolved near the Cretaceous South Pole. It is not a management analogue for modern peatlands, but it reinforces the broader idea that fire can be formative as well as destructive.

## CAVEATS / UNCERTAINTY

This is a deep-time reconstruction using geological and biological proxies. It is not direct guidance for managing present-day peatland fires.

Ecological outcomes depend on context: the intervention, the place, the system and the timescale.
