Evidence

Peer-reviewed

Geography

High-elevation western North American forest; 1992/2017 fires

System

Subalpine fire recurrence and succession

## WHAT THE EVIDENCE SAYS

A field comparison of unburned, once-burned and reburned high-elevation forest found high-severity reburns could support abundant young stems dominated by early colonizers such as lodgepole pine or deciduous trees, with few of the usual shade-tolerant conifers. Understory species did not respond like saplings.

## WHY IT MATTERS / OUR READ

Tree counts and greenness alone may disguise a compositional shift. Track identity of regrowth, fire severity and surviving seed-source distance.

## CAVEATS / UNCERTAINTY

Single site, early recovery and nonuniform severity effects; permanent state change is not established.
