Context:Landscape and local factors govern tree regeneration across heterogeneous post-fire forest environments. But their relative influence is unclear—limiting the degree that managers can consider landscape context when delegating resources to…

Objective:To identify physiologic stressors related to cardiovascular disease via changes in metabolic, inflammatory, and oxidative stress biomarkers during 2 weeks of preseason training in wildland firefighters (WLFFs).
Methods:Participants were…

Wildland fires have been a rising problem on the worldwide level, generating ecological and economic losses. Specifically, between wildland fire types, uncontrolled fires are critical due to the potential damage to the ecosystem and their effects on…
Year Published:
Wildfire activity in the western United States has been increasing since the 1970s, with many fires occurring on land managed by government agencies. Over six million acres of public lands are surrounded by private land and lack road access, making…
Year Published:
Scarcity in wildland fire progression data as well as considerable uncertainties in forecasts demand improved methods to monitor fire spread in real time. However, there exists at present no scalable solution to acquire consistent information about…
Year Published:
While managed fire often produces clear changes in aboveground functional diversity, we know little about how fire affects belowground fauna and their mediation of biogeochemical processes. Because soil micro- and mesofauna, particularly nematodes,…
Year Published:
Wildfire-generated snags provide key habitat for wildlife associated with recently disturbed forests, offering nesting and foraging resources for several woodpecker species. Snag harvest through post-fire salvage logging provides economic value but…
Year Published:
Abrupt changes in wind direction and speed caused by thunderstorm-generated gust fronts can, within a few seconds, transform slow-spreading low-intensity flanking fires into high-intensity head fires. Flame heights and spread rates can more than…
Year Published:
Large and severe wildfires are becoming increasingly common worldwide and are having extraordinary impacts on people and the species and ecosystems on which they depend. Indigenous peoples comprise only 5% of the world’s population but protect…
Year Published:
Climate change is projected to exacerbate the intensity of heat-waves and drought, leading to greater incidences of large and high-intensity wildfires in forested ecosystems. While commonly-used remotely-sensed spectral assessments can provide…
Year Published:
Global change has resulted in chronic shifts in fire regimes. Variability in the sensitivity of tree communities to multi-decadal changes in fire regimes is critical to anticipating shifts in ecosystem structure and function, yet remains poorly…
Year Published:
The spatial overlap of multiple ecological disturbances in close succession has the capacity to alter trajectories of ecosystem recovery. Widespread bark beetle outbreaks and wildfire have affected many forests in western North America in the past…
Year Published:
Altered climate, including weather extremes, can cause major shifts in vegetative recovery after disturbances. Predictive models that can identify the separate and combined temporal effects of disturbance and weather on plant communities and that…
Year Published:
In recent years wildland fires in the United States have had significant impacts on local and regional air quality and negative human health outcomes. Although the primary health concerns from wildland fires come from fine particulate matter (PM2:5…
Year Published:
Formal regulation of private property and exploration of 'risk transmission' across ownerships are two popular means for addressing wildfire management at landscape scales. However, existing studies also indicate that a number of barriers exist for…
Year Published:
Wildfires in forest ecosystems have been well studied, while wildfires in rangelands ecosystems have received less attention. This study evaluated temporal trends of large wildfires on rangelands in western US from 1984 to 2017, using the Monitoring…
Year Published:
Wildfires in many western North American forests are becoming more frequent, larger, and severe, with changed seasonal patterns. In response, coniferous forest ecosystems will transition toward dominance by fire-adapted hardwoods, shrubs, meadows,…

We celebrate the 50th anniversary of the Canadian Journal of Forest Research by reflecting on the considerable progress accomplished in select areas of Canadian wildland fire science over the past half century. Specifically, we discuss key…

The Enemy Release Hypothesis proposes that invasion by exotic plant species is driven by their release from natural enemies (i.e. herbivores and pathogens) in their introduced ranges. However, in many cases, natural enemies, which may be introduced…

Assessing the Safety of Training Firefighters with the Minimum Requirements for Firefighter Garments
Every year, high numbers of firefighters are injured at fire incidents. A primary cause of moderate to severe injury can be linked to the protective garments worn by firefighters and understanding the limits of these protective garments is crucial…
