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…

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…

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…

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…

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…

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…

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.…

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…

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…

1. Climate, disturbance, vegetation response, and their interaction are key factors in predicting the distribution and function of ecosystems across landscapes. A range of factors, operating through different pathways, are amplifying the feedbacks…

Background: There has been little quantification of the extent and duration of micrometeorological changes within a forest after airtanker drops of water-based suppressant. It has been speculated that a period of prolonged relative humidity –…
Year Published:
The influence of forest treatments on wildfire effects is challenging to interpret. This is, in part, because the impact forest treatments have on wildfire can be slight and variable across many factors. Effectiveness of a treatment also depends on…
Year Published:
Prescribed fire is a useful tool for building resilient landscapes in fire-prone areas across the globe. In the western U.S., prescribed fire is employed by federal, state, and Tribal land managers and planned during particular meteorological and…
Year Published:
By all measures, wildfires in the western United States are becoming more extreme. Fires are growing larger and burning more intensely, and suppression costs are spiraling upward. Maximizing the effectiveness of fuel treatments at the landscape…
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…
Year Published:
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:
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…
