Background: Due to anthropogenic climate change and historic fire suppression, wildfire frequency and severity are increasing across the western United States. Whereas the indirect effects of fire on wildlife via habitat change are well studied,…

Fire is an inherently evolutionary process, even though much more emphasis has been given to ecological responses of plants and their associated communities to fire.
Here, we synthesize contributions to a Special Feature entitled 'Fire as a dynamic…
Year Published:
Many tools that identify wildfire risks and hazards across the landscape assume that all houses and properties within a community have the same level of risk. However, there are often substantial differences across properties, such as building…
Year Published:
Falling trees and tree fragments are one of the top five leading causes of fatalities for wildland fire responders. Wildfires - along with insect infestations, drought, disease, and other disturbances - have increased dead and dying trees in forests…

This paper aims to provide a better understanding of the transition towards a new paradigm of wildfire risk management in Victoria that incorporates Aboriginal fire knowledge. We show the suitability of cultural burning in the transformed landscapes…

Background
Native pinyon (Pinus spp.) and juniper (Juniperus spp.) trees are expanding into shrubland communities across the Western United States. These trees often outcompete with native sagebrush (Artemisia spp.) associated species, resulting in…
Year Published:
Fire has shaped ecological communities worldwide for millennia but impacts of fire on individual species are often poorly understood. We performed a meta-analysis to predict which traits, habitat or study variables, and fire characteristics…
Year Published:
A deeper understanding of the influence of fine-scale fuel patterns on fire behavior is essential to the design of forest treatments that aim to reduce fire hazard, enhance structural complexity, and increase ecosystem function and resilience. Of…

Monitoring ecosystem status and recovery potential is critical for natural resource management. Recent evidence in ecological studies suggest a fundamental link between ecosystem physical structure and function, including resistance and recovery.…
Year Published:
Building containment lines and removing fuels can bring wildland firefighters close to advancing flames. In these high-risk situations, firefighters depend on safety zones - large, open areas with little flammable material where they can retreat if…
Year Published:
Structure loss is an acute, costly impact of the wildfire crisis in the western conterminous United States (“West”), motivating the need to understand recent trends and causes. We document a 246% rise in West-wide structure loss from wildfires…

Background
Increases in fire activity and changes in fire regimes have been documented in recent decades across the western United States. Climate change is expected to continue to exacerbate impacts to forested ecosystems by increasing the…
Year Published:
Fire regimes in sagebrush (Artemisia spp.) ecosystems have been greatly altered across the western United States. Broad-scale invasion of non-native annual grasses, climate change, and human activities have accelerated wildfire cycles, increased…
Year Published:
Background: Previously established correlations of flame length L with fireline intensity IB are based on theory and data which showed that flame zone depth D of a line fire could be neglected if L was much greater than D.
Aims: We evaluated this…
Year Published:
The surface fire spread involved slope and wind effects are significantly important in wildland fires, while very limited attention has been paid on the heat transfer mechanism, especially for different fire line conditions. This work experimentally…
Year Published:
An experimental study at a laboratory scale that aims to compare the fire behaviour in two configurations: a regular flat slope and a slope with an embedded canyon. In configurations of slope with an embedded canyon, a rapid increase in the rate of…
Year Published:
Wildfire spread models that couple physical transport and chemical kinetics sometimes simplify or neglect gas-phase pyrolysis product oxidation chemistry. However, empirical evidence suggests that oxygen (O2) is available for gas-phase and solid-…
Year Published:
Biodiversity is in chronic decline, and extreme events - such as wildfires - can add further episodes of acute losses. Fires of increasing magnitude will often overwhelm response capacity, and decision-makers need to make choices about what to…
Year Published:
As the 2023 fire season rages with unprecedented intensity in Canada, millions of people and countless animals across North America are exposed to wildfire smoke. Its harmful effects on human and animal health are only beginning to be explored in…
Year Published:
Interactions between vegetation and sediment in post-fire landscapes play a critical role in sediment connectivity. Prior research has focused on the effects of vegetation removal from hillslopes, but little attention has been paid to the effects of…
