Stephens et al. (2020) do an excellent job of encouraging us to sharpen our focus on the ecological consequences of forest and fire management activities, but at the same time they did not emphasize that those consequences differ substantially among…

Background: Evidence from previous studies suggests that women firefighters have greater risk of some adverse reproductive outcomes. The purpose of this study was to investigate whether women firefighters had greater risk of miscarriage compared to…

Forests store significant quantities of carbon, and accurate quantification of the fate of this carbon after fire is necessary for global carbon accounting. Pyrogenic carbon (PyC) encompasses various carbonaceous products of incomplete combustion…

Wildland fire shaped the historical ponderosa pine and mixed-conifer forest landscapes throughout the West. Fire was also a controlling force in most of the drier vegetation types, ranging from shortgrass prairie to chaparral, scrub oak, and pinyon–…

Increased wildfire activity and climate change have intensified disturbance regimes globally and have raised concern among scientists and land managers about the resilience of disturbed landscapes. Here we test the effects of climate, topographic…

Climate warming is expected to increase fire frequency in many productive obligate seeder forests, where repeated high-intensity fire can initiate stand conversion to alternative states with contrasting structure. These vegetation–fire interactions…

Knowledge of how factors such as climate, plant regeneration traits and fire characteristics influence the rate and pattern of post-fire habitat change is crucial for strategic fire management and biodiversity conservation in fire-affected areas.…

Restoration of fire-prone forests is a common practice intended to increase resilience to wildfire, drought, and bark beetles. However, the long-term effects of restoration treatments on understory species, particularly non-native species, are…

Fuel mapping is key to fire propagation risk assessment and regeneration potential. Previous studies have mapped fuel types using remote sensing data, mainly at local-regional scales, while at smaller scales fuel mapping has been based on general-…

This preview extrapolates the future increase in burn area predicted by Chao Wu et al. in this issue of One Earth to consider the inevitable increase in fire-derived pollution and implication to human health. Although these global-scale predictions…

The intersection of expanding human development and wildland landscapes—the “wildland–urban interface” or WUI—is one of the most vexing contexts for fire management because it involves complex interacting systems of people and nature. Here, we…

In recent decades, climate change has lengthened wildfire seasons globally and doubled the annual area burned. Thus, capturing fire dynamics is critical for projecting Earth system processes in warmer, drier, more fire prone future. Recent advances…

Fire has always been a driving factor of life on Earth. Now that mankind has definitely joined the other environmental forces in shaping the planet, lots of species are threatened by human-induced variation in fire regimes. Soil-dwelling organisms,…

Forested ecosystems cover nearly one-third of Earth’s land surface and can perform an essential function as one of the globe’s largest terrestrial carbon sinks, absorbing more carbon than they release, lowering the concentration of carbon dioxide in…

Identifying the number of firebrands generated during wildfires is an important aspect of understanding their propagation. A key challenge in quantifying the number of firebrands released is to distinguish those that are ‘hot’ and could lead to…
