Fire effects on ecosystems

Wildfires are not merely destructive events but integral processes that shape vegetation structure, nutrient cycles, and the long-term carbon balance of ecosystems ranging from tropical savannas to boreal forests. As climate change drives hotter, drier conditions across much of the planet, fire regimes — the characteristic patterns of frequency, intensity, and extent — are shifting in ways that outpace the adaptive capacity of many ecosystems, turning forests from carbon sinks into significant sources of atmospheric emissions. Researchers are working to understand how altered fire behavior affects soil chemistry, post-fire recovery, and the resilience of vegetation communities under repeated disturbance. Central open questions include how boreal and temperate forests will reorganize over coming decades as fire return intervals shorten, and whether remote sensing tools can provide the spatial and temporal resolution needed to close persistent gaps in global fire emissions accounting.
