Description
Claudia Leal-Medina and co-authors present a 2026 study on a rare Chilean forest after a megafire. The native beech-like tree survives only in fragments, ringed by plantations of an exotic pine. The 2017 fire burned across this landscape at varied severity. The team measured severity from satellite images and tracked regrowth from 2018 to 2021, plus seedling counts and tree-ring growth.
Ground cover bounced back fast in moderate and severe burn zones. The native tree regrew mainly by sprouting from stumps, with higher sprout rates in harder-burned sites. Its ring growth did not differ by severity. The exotic pine, by contrast, grew faster under high severity and outgrew the native tree there. Fire severity thus tilts the race toward the invader.
