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…

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…

Elevated fuel loads represent a wildfire hazard in a landscape. Reducing fuel load is one mitigation strategy commonly employed to decrease the severity and impact of wildfires. The planning of such fuel management operations, however, represents a…

Whitebark pine (WBP; Pinus albicaulis) is a critical keystone species of U.S. Northern Rocky Mountain subalpine ecosystems. There is growing concern that WBP may be eliminated from its current habitat over the next century due to cumulative impacts…

Human and natural disturbances are key drivers of change in forest ecosystems. Yet, the direct and indirect mechanisms which underpin these changes remain poorly understood at the ecosystem level. Here, using structural equation modelling across a…

Wildland fire activity and associated emission of particulate matter air pollution is increasing in the United States over the last two decades due primarily to a combination of increased temperature, drought, and historically high forest fuel…

Northern Eurasia is currently highly sensitive to climate change. Fires in this region can have significant impacts on regional air quality, radiative forcing and black carbon deposition in the Arctic which can accelerate ice melting. Using a MODIS-…

Background: Weather plays an integral role in fire management due to the direct and indirect effects it has on fire behavior. However, fire managers may not use all information available to them during the decision-making process, instead utilizing…

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…

Climate warming and increased frequency and severity of wildfires have the potential to undermine forest resilience to wildfires. Species demography implies that vegetation responses to fires depend on a series of population filters, including adult…

Abrupt changes in wind direction and speed can dramatically impact wildfire development and spread. Most importantly, such changes can pose significant problems to firefighting efforts and have resulted in a number of fire fatalities over the years…

Trees in dry forests often regenerate in episodic pulses when wet periods coincide with ample seed production. Factors leading to success or failure of regeneration pulses are poorly understood. We investigated the impacts of stand thinning on…
