Background
Catastrophic wildfire has escalated across the globe in recent decades with devastating consequences for human communities and native ecosystems. Global change processes, including climate warming and land use practices, are altering…

Background
Potential heat release (PHR) is the theoretical maximum amount of heat releasable by wildland fuels during fire and is a key determinant of fireline intensity. Understanding its variability and dynamics is important for predicting fire…

The Northern Rocky Mountains, USA contain a vast forested landscape, managed primarily by the federal government. This region contains some of the highest elevations forests and most iconic endangered and threatened species in the contiguous United…
Year Published:
Wildfire activity has accelerated with climate change, sparking concerns about uncharacteristic impacts on mature and old-growth forests containing large trees. Recent assessments have documented fire-induced losses of large-tree habitats in the US…

Prescribed fire is an important tool for management of many ecosystems, but often there is a gap between how much managers would like to see fire used and how often it actually is. In this piece, the Northern Rockies Fire Science Network explores…

Ensuring proper sizing and fit for U.S. female firefighters’ personal protective clothing and equipment (PPE) is a crucial challenge for researchers and manufacturers. The National Fire Protection Association (NFPA) establishes design and…

Anthropogenic subsidies and disturbance can benefit generalist avian species by providing additional food, nesting, and perching resources. In the sagebrush biome, anthropogenic subsidies have led to increases in the number of common ravens (Corvus…

Aspen (Populus tremuloides) forests are generally thought to impede fire spread, yet the extent of this effect is not well quantified in relation to other vegetation types. We examined the influence of aspen cover on interpolated daily fire spread…
Year Published:
Increased fire activity in the western United States since 2000 has produced an abundance of fire-injured trees at risk to lethal attack by bark beetles. Large populations of bark beetles reproducing in fire-injured trees may disperse (or spillover…

Background
Fuel moisture content is a key driver of fuel flammability and subsequent fire activity and behavior worldwide. Dead fuels passively exchange moisture with the atmosphere while live fuel moisture is confounded by a mixture of seasonal…

Background
Following high-severity wildfires in conifer forests that rely on wind dispersal for regeneration, reforestation practices are used to hasten the development of large, fire-resistant trees that are better able to persist through the next…
Year Published:
This study aimed to develop the Five Cognitive Biases in Risk-Taking Scale (5 CBR-S) to measure five cognitive biases associated with risk-taking: overconfidence, illusion of control, belief in the law of small numbers, escalation of commitment, and…
Year Published:
Forest ecology focuses on the structure, functions, and ecosystem services of forests, which is crucial for understanding the impacts of forest fires on these systems. Forest fires not only have a negative impact on forests but also threaten their…
Year Published:
Altered fire regimes are a global challenge, increasingly exacerbated by climate change, which modifies fire weather and prolongs fire seasons. These changing conditions heighten the vulnerability of ecosystems and human populations to the impacts…
Year Published:
Background
Forest ecosystems function as the largest terrestrial carbon sink globally. In the Western US, fires play a crucial role in modifying forest carbon storage, sequestration capacity, and the transfer of carbon from live to dead carbon pools…
