Fire Effects and Fire Ecology
Fuel constraints, not fire weather conditions, limit fire behavior in reburned boreal forests
Year of Publication
2024
Publication Type
Fire frequency in boreal forests has increased via longer burning seasons, drier conditions, and higher temperatures. However, fires have historically self-regulated via fuel limitations, mediating the effects of changes in climate and fire weather.
Expanding our understanding of nitrogen dynamics after fire: how severe fire and aridity reduce ecosystem nitrogen retention
Year of Publication
2024
Publication Type
Fires release large pulses of nitrogen (N), which can be taken up by recovering plants and microbes or exported to streams where it can threaten water quality. The amount of N exported depends on the balance between N mineralisation and rates of N uptake after fire. Burn severity and soil moisture interact to drive these rates, but their effects can be difficult to predict.
Changing fire regimes and nuanced impacts on a critically imperiled species
Year of Publication
2024
Publication Type
Wildfire activity throughout western North America is increasing which can have important consequences for species persistence. Native species have evolved disturbance-adapted traits that confer resilience to natural disturbance provided disturbances operate within their historical range of variability.
Drivers and Impacts of the Record-Breaking2023 Wildfire Season in Canada
Year of Publication
2024
Publication Type
The 2023 wildfire season in Canada was unprecedented in its scale andintensity, spanning from mid-April to late October and across much of theforested regions of Canada. Here, we summarize the main causes and impactsof this exceptional season.
Carbon emissions from the 2023 Canadian wildfires
Year of Publication
2024
Publication Type
The 2023 Canadian forest fires have been extreme in scale and intensity with more than seven times the average annual area burned compared to the previous four decades. Here, we quantify the carbon emissions from these fires from May to September 2023 on the basis of inverse modelling of satellite carbon monoxide observations.
Trees have similar growth responses to first-entry fires and reburns following long-term fire exclusion
Year of Publication
2024
Publication Type
Managing fire ignitions for resource benefit decreases fuel loads and reduces the risk of high-severity fire in fire-suppressed dry conifer forests. However, the reintroduction of low-severity wildfire can injure trees, which may decrease their growth after fire.
Untrammeling the wilderness: restoring natural conditions through the return of human-ignited fire
Year of Publication
2024
Publication Type
Historical and contemporary policies and practices, including the suppression of lightning-ignited fires and the removal of intentional fires ignited by Indigenous peoples, have resulted in over a century of fire exclusion across many of the USA’s landscapes.
