Disaster risk management tipping points: impacts of extreme wildfire events and the resulting need for layered disaster risk management solutions
Year: 2025
Wildfire regimes are changing globally with an increase in global burned area and changes in fire characteristics. Recent research shows that the number of extreme fire events is increasing exponentially and events such as the most recent fires in Los Angeles in the U.S. (2025), the Hawaii fires (2023), Canada’s record-breaking fires (2023), the largest recorded fires in Greece-Europe (2023) and the 2025 European fire season underpin this observation.Extreme wildfire events (EWEs) thereby pose new challenges and limits to managing disaster risk. This refers not only to response operations but…

Global Synthesis of Quantification of Fire Behaviour Characteristics in Forests and Shrublands: Recent Progress
Year: 2025
Purpose of ReviewThe behaviour of wildland fires, namely their free spreading nature, destructive energy fluxes and hazardous environment, make it a phenomenon difficult to study. Field experimental studies and occasional wildfire observations underpin our understanding of fire behaviour. We aim to present a global synthesis of field-based studies in forest and shrublands fuel types published since 2003 with a focus on the most commonly measured fire behaviour attributes, namely rate of fire spread, ignition and spread sustainability, flame characteristics, fuel consumption…

Frequent, heterogenous fire supports a forest owl assemblage
Year: 2025
Fire shapes biodiversity in many forested ecosystems, but historical management practices and anthropogenic climate change have led to larger, more severe fires that threaten many animal species where such disturbances do not occur naturally. As predators, owls can play important ecological roles in biological communities, but how changing fire regimes affect individual species and species assemblages is largely unknown. Here, we examined the impact of fire severity, history, and configuration over the past 35 years on an assemblage of six forest owl species in the Sierra Nevada, California,…
