Does large area burned mean a bad fire year? Comparing contemporary wildfire years to historical fire regimes informs the restoration task in fire-dependent forests

Donato, Halofsky, Churchill, Haugo, Cansler, Smith, Harvey
Wildfires and fire seasons are commonly rated largely on the simple metric of area burned (more hectares: bad). A seemingly paradoxical narrative frames large fire seasons as a symptom of a forest health problem (too much fire), while simultaneously…

Examining socioeconomic factors associated with wildfire occurrence and burned area in Galicia (Spain) using spatial and temporal data

de Diego, Fernández, Rúa, Kline
Background: The Spanish region of Galicia is one of the most fire-prone areas in Europe. Most wildfires are directly or indirectly related to human activities, suggesting that socioeconomic factors likely can inform wildfire management.…

Exceptional variability in historical fire regimes across a western Cascades landscape, Oregon, USA

Johnston, Schmidt, Merschel, Downing, Coughlan, Lewis
Detailed information about the historical range of variability in wildfire activity informs adaptation to future climate and disturbance regimes. Here, we describe one of the first annually resolved reconstructions of historical (1500-1900 ce) fire…

Human activity and demographics drive the fire regime in a highly developed European boreal region

Sjöström, Granström
Organization of successful wildfire prevention and suppression require detailed information on ignition causes, size distributions and relations to weather. From a large and highly detailed dataset of Swedish wildfire incidents (n = 124 000) we…

Humans and climate modulate fire activity across Ethiopia

Harris, Taylor, Kassa, Leta, Powell
Background: Fire occurrence is influenced by interactions between human activity, climate, and fuels that are difficult to disentangle but crucial to understand, given fire’s role in carbon dynamics, deforestation, and habitat maintenance,…
