- Description: Post-fire nests suggest microhabitat shelter can matter more than a broad burned/unburned classification.

Evidence

Peer-reviewed

Geography

Côte Bleue shrubland, southern France

System

Wild bee nesting; fire refugia and microclimate

## WHAT THE EVIDENCE SAYS

After a 2025 wildfire, a study examined nesting outcomes for a solitary bee using snail shells. Survival or adult emergence differed between protected microsites and exposed burned nesting areas.

## WHY IT MATTERS / OUR READ

Fire ecology may need to measure very small refuges, stones and nesting structures as well as remotely mapped severity; the signal is worth following in replicated studies.

## CAVEATS / UNCERTAINTY

One fire and a specialized bee species do not establish a population trend, a transferable intervention or a generalized benefit of severe fire.
