Determining whether forest landscapes can maintain their resilience to fire – that is, their ability to rebound and sustain – given rapid climate change and increasing fire activity is a pressing challenge throughout the American West. Many western…

Wildfire is a major driver of nitrogen (N) cycling and export from terrestrial to aquatic systems. While fire is a natural process in many watersheds, it can still degrade water quality by rapidly flushing N to streams. This can be particularly…

Subalpine forests that historically burned every 100–300 yr are expected to burn more frequently as climate warms, perhaps before trees reach reproductive maturity or produce a serotinous seedbank. Tree regeneration after short‐interval (<30‐yr)…

Climate change is expected to increase fire activity in many regions of the globe, but the relative role of human vs. lightning-caused ignitions on future fire regimes is unclear. We developed statistical models that account for the spatiotemporal…

In recent years Unmanned Aerial Vehicles (UAVs) have progressively been utilized for wildfire management, and are especially in prevalent in forest fire monitoring missions. To ensure the fast detection and accurate area estimation of forest fires,…

The public health emergency associated with the 2019–20 bushfires in Australia was a wake-up call to increase the resilience of our health systems to respond to climate extremes. We must combine our understanding of predictions of extreme weather…

The year 2020 brought unimaginable challenges in public health, with the confluence of the COVID-19 pandemic and wildfires across the western United States. Wildfires produce high levels of fine particulate matter (PM2.5). Recent studies reported…

n August 1910, wildfires swept through 3 million acres (1.6 million ha) of heavily forested mountain country in northern Idaho and adjacent Montana. About 85 people perished in the flames, and the Forest Service’s fire protection program was caught…

Concern about the impacts of two invasive annual brome grasses (cheatgrass and Japanese brome, Bromus tectorum L. and B. japonicus Thunb. ex Murray) on the mixed-grass prairie of North America's northern Great Plains (NGP) is growing. Cheatgrass is…

The benefits of prescribed fires are recognized throughout the United States, but the ability to assist with prescribed fire application on private land by government agencies has many possible constraints and challenges. The Natural Resources…

Following the 2020 wildfires in Australia an extremely large amount of smoke entered the stratosphere and was dispersed throughout the southern hemisphere stratosphere. However, the pathway and entry point of the smoke into the stratosphere and the…

Increases in Vapor Pressure Deficit (VPD) have been hypothesized as the primary driver of future fire changes. The Coupled Model Intercomparison Project phase 5 (CMIP5) models agree that western U.S. surface temperatures and associated dryness of…

As we learn to sustainably coexist with wildfire, there is an urgent need to improve our understanding of its multidimensional impacts on society. To this end, we undertake a nationwide study to estimate how megafires (wildfires > 100,000 acres…
Year Published:
While fire is an important ecological process in the western United States, wildfire size and severity have increased over recent decades as a result of climate change, historical fire suppression, and lack of adequate fuels management. Due to the…
Year Published:
Computer models used to predict forest and fuels dynamics and wildfire behavior inform decisionmaking in contexts such as postdisturbance management. It is imperative to understand possible uncertainty in model predictions. We evaluated sensitivity…
Year Published:
Native grasslands have been vastly transformed with the expansion of human activities. Applied fire regimes offer conservation-based management an opportunity to enhance remaining grassland biodiversity and secure its persistence into the future.…
Year Published:
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…
Year Published:
Wildfires significantly influence ecosystem patterns and processes on a global scale. In many cases, they pose a threat to human lives and property. Through greenhouse gas emissions, wildfires also directly contribute to climate change. The…
Year Published:
As global warming continues, wildland lightning fires have exhibited an increasing trend. The phenomenon of lightning ignition and a model are urgent research fields. In this study, an impulse current generator was used to study artificial lightning…
Year Published:
Wildfires are occurring more frequently and with greater severity domestically and around the globe. Across a series of studies, researchers at the University of Idaho set out to identify how and when climate variability affects wildfire frequency…
