Evidence

Peer-reviewed

Geography

Western United States; biodiversity and fire-exposure modeling

System

Forest birds; changing fire regimes; biodiversity risk modeling

## WHAT THE EVIDENCE SAYS

Researchers combined western U.S. bird-distribution maps with fire-severity predictions based on landscape and climate conditions in 2016\. About 55–58% of mapped biodiversity hotspots intersected predicted low-severity fire and were classified as potential refugia; 24–30% intersected predicted high severity and were areas of concern. Roughly 52–60% of those concern areas historically experienced low-severity fire regimes. The model estimates severity conditional on a fire occurring, not ignition timing or a future warming scenario.

## WHY IT MATTERS / OUR READ

The useful planning move is to overlay diversity priorities with expected disturbance character, not treat all hotspots as uniformly protected or uniformly threatened. Habitat refugia designation should be paired with field validation and species-response monitoring.

## CAVEATS / UNCERTAINTY

These percentages describe modeled spatial classes, not measured future species losses. The severity product represents 2016 conditions and may miss subsequent fuel changes; it is not a forecast of future climate or when a fire will occur. High-severity fire does not affect every species equally.
