Land treatments in wildland-urban interface (WUI) areas are highly visible and subject to public scrutiny and possible opposition. This study examines a contested vegetation treatment-Forsythe II-in a WUI area of the Arapaho-Roosevelt National…

The increasing amount of high-severity wildfire in historical low and mixed-severity fire regimes in western US forests has created a need to better understand the ecological effects of different post fire management approaches. For three different…

Spotting during wildfires can significantly influence the way wildfires spread and reduce the chances of successful containment by fire crews. However, there is little published empirical evidence of the phenomenon. In this study, we have analysed…

Large conflagrations of informal settlements occur regularly, leaving thousands of people homeless daily and taking tens of thousands of lives annually. Over the past few years, a large amount of data has been collected from a number of full-scale…

Wildland firefighters are directly exposed to elevated levels of wildland fire (WF) smoke. Although studies demonstrate WF smoke exposure is associated with lung function changes, few studies that use invasive sample collection methods have been…

The unprecedented 2015 wildfire season in northern Saskatchewan, Canada resulted in the largest evacuation in the province's history. The depiction of such environmental hazards in the news media is one mechanism that can, even inadvertently,…

The structure and composition of sagebrush‐dominated ecosystems have been altered by changes in fire regimes, land use, invasive species, and climate change. This often decreases resilience to disturbance and degrades critical habitat for species of…

Monitoring ecosystem events such as wildfires with remote sensing is fundamental to natural resources management. However, precisely delineating burned areas with remote sensing remains a challenge for post-fire ecological assessment. Burned area…

Many large fires have burned in recent decades across western North America, and this trend is projected to continue as conditions become warmer and drier. Recovery processes have been studied more thoroughly 1-2 years post fire than in the longer…

Recovery after a wildfire is a process, both at the community or larger scale and for individuals. The United Nations Office for Disaster Risk Reduction (UNISDR) defines recovery as, “The restoring or improving of livelihoods and health, as well as…

During the past century, systematic wildfire suppression has decreased fire frequency and increased fire severity in the western United States of America. While this has resulted in large ecological changes aboveground such as altered tree species…

“Coproduction” as a transformative model for fire science application is receiving increasing attention as wildland fire managers face increasingly complex contexts for prescribed fire applications and wildfire suppression (Hiers 2017). Among…

Wildfires are a significant agent of disturbance in forests and highly sensitive to climate change. Short-interval fires and high severity (mortality-causing) fires in particular, may catalyze rapid and substantial ecosystem shifts by eliminating…

Globally, wildfires are increasing in frequency and severity, exposing populations to toxic trace elements stored within forests. Trace element and Pb isotope compositions in aerosols (n = 87) from four major wildfires near Sydney, Australia (1994-…

Evacuation is the preferred method in the U.S. for preserving public safety in wildfire. However, alternatives such as staying and defending are used both in North America and Australia. Dangerous delays in the decision to evacuate are also common.…

Legacy effects from one disturbance may influence successional pathways by amplifying or buffering forest regeneration after the next disturbance. We assessed vegetation and tree regeneration in non-serotinous Sierra lodgepole pine (Pinus contorta…

Warming‐induced mountain pine beetle (Dendroctonus ponderosae; MPB) outbreaks have caused extensive mortality of whitebark pine (Pinus albicaulis; WBP) throughout the species’ range. In the highest mountains where WBP occur, they cross alpine…
