What to know about Fast-moving wildfires may prevent western forests from recovering

A study published in Science Advances suggests that fast-moving, severe wildfires in western North America may prevent conifer forests from recovering, potentially leading to a transition toward shrublands or grasslands. Researchers emphasize that fire speed, driven by drought and climate change, increases tree mortality and limits the availability of seed trees for natural regeneration.

What happened

Fast-moving wildfires may prevent western forests from recovering Robert Egan Senior Editor The severe, drought-fueled fires now burning across much of the American West and Canada may be scorching forests so thoroughly that they cannot recover to the forests…

Why it matters

A study by Colorado State University, Western Colorado University and others found that the fastest-moving forest fires not only burn more area but also burn more severely, leaving fewer surviving trees to reseed the landscape and opening the door to…

Common ground

The study, published in Science Advances, examined nearly 3,500 wildfires that burned in conifer forests across western North America between 2012 and 2023.
