The essentials
Wildfires destroyed twice as much forest in three years as the preceding two decades.
Wildfire activity reached unprecedented levels in 2025, with Canada experiencing the destruction of 5.3 million hectares of forest. European nations faced severe impacts, as France reported a 7-fold increase in forest loss from wildfires, while Spain and Portugal together experienced 60% tree loss from fire damage.
The scale of destruction represents a dramatic acceleration in forest loss globally. Notably, wildfires destroyed twice as much forest cover in the past three years as in the entire preceding two decades, signaling a sharp intensification of the threat. These figures underscore the widening vulnerability of forest ecosystems to fire across multiple regions simultaneously.

2025 Wildfires Set New Benchmarks for Continental Forest Loss
The 2025 wildfire season produced measurable losses across three continents. Canada's 5.3 million hectares represents the largest single regional loss, while European impacts were severe but geographically concentrated. France's 7-fold increase and Spain-Portugal's 60% tree loss illustrate regional variation in fire intensity and forest vulnerability across different ecosystems.
Wildfire Acceleration Outpaces Two Decades of Prior Destruction
The comparison of recent destruction to historical baselines reveals a fundamental shift in wildfire patterns. Three years of current destruction equals twice the forest loss of the preceding 20 years, suggesting conditions favoring increased fire activity. This acceleration affects multiple continents, indicating systemic changes rather than localized phenomena affecting forest stability globally.
