A mismatch in wildfire impact reduction and ecological restoration in western U.S. fuel treatments

Fuel treatments in western U.S. forests increase tree survival, but the gains are greatest for fire-intolerant trees, fade within nine years, and do not shift seedlings toward fire-tolerant species.

• Why it matters: Fire suppression has left many forests denser and dominated by fire-intolerant trees, so severe wildfires are more likely, while restoration goals may conflict with impact reduction.
• What they did: Using Forest Inventory and Analysis data on 81,621 trees and 41,328 seedlings from 11 western U.S. states, the study assessed how fuel treatments affect survival and seedling composition over time.
• The result: Treatments reduce wildfire impacts via improved survival, yet they show no seedling composition shift toward fire-tolerant species, implying that long-term resilience may require repeated intervention without redesign.
