All wildfires in the United States are managed, but the strategies used to manage them vary by region and season. “Managed wildfire” is a response strategy to naturally ignited wildfires; it does not prioritize full suppression and allows the fire…

Background
Trends of increasing area burned in many regions worldwide are leading to more locations experiencing short-interval reburns (i.e., fires occurring two or more times in the same place within 1–3 decades). Field and satellite indices of…

Investigates whether a cultural burning program embedded within a government bureaucracy can meaningfully support Indigenous peoples’ landscape fires. In particular, it presents evidence on how Indigenous and non-Indigenous individuals encountered,…

In May of this year, USDA Forest Service Chief Randy Moore put a 90-day moratorium on all prescribed burns on lands administered by the forest service, following the Calf Canyon/Hermits Peak fire in New Mexico that started after prescribed burn…

Across western North America, fire regimes (i.e., the frequency, extent, and severity of fire events) are changing in response to warming climate. Regions in which fire regimes are driven by top-down controls (e.g., climate, fire weather) are likely…

Airtankers are commonly used for initial attack (IA) to reduce the likelihood of wildland fires escaping containment efforts. We examined IA airtanker dispatch decisions for forest fires in Ontario, Canada, through an analysis of historical fire…
Year Published:
Understanding the role of land use type and topographic features in shaping wildfire regimes received much attention because of the intensification of wildfire activities. The intensifying wildfires in the western United States are a great concern…

An extreme drought from 2012–2016 and concurrent bark beetle outbreaks in California, USA resulted in widespread tree mortality. We followed changes in tree mortality, stand structure, and surface and canopy fuels over four years after the peak of…
Year Published:
Western juniper was often historically restricted to fire refugia such as rocky outcrops but has since Euro-American settlement expanded into areas previously dominated by sagebrush steppe. Wildfires in developed woodlands have been rare. In 2007,…

Productivity is strongly associated with terrestrial species richness patterns, although the mechanisms underpinning such patterns have long been debated. Despite considerable consumption of primary productivity by fire, its influence on global…
Year Published:
The structure and fire regime of pre-industrial (historical) dry forests over ~26 million ha of the western USA is of growing importance because wildfires are increasing and spilling over into communities. Management is guided by current conditions…
Year Published:
Wildfires change the hydrologic and geomorphic response of watersheds, which has been associated with cascades of additional hazards and management challenges. Among these post-wildfire events are shallow landslides and debris flows. This study…
Year Published:
Achieving sustainable coexistence with wildfires in the Anthropocene requires skilful integrated fire observations, fire behaviour predictions, forecasts of fire risk, and projections of change to fire climates. The diverse and multiscale approaches…
Year Published:
Over the past couple of decades, the number of wildfires and area of land burned around the world has been steadily increasing, partly due to climatic changes and global warming. Therefore, there is a high probability that more people will be…
Year Published:
For decades, large portions of the semi-arid sagebrush ecosystem have been experiencing increased frequency and extent of wildfire, even though small, infrequent fire is a natural disturbance in this ecosystem (Baker, 2006). Increased wildfire…

Background: Predators and fire shape ecosystems across the globe and these two forces can interact to impact prey populations. This issue is particularly pertinent in Australia where there is considerable scientific and public interest in the post-…
Year Published:
Wildfires are increasing in frequency and intensity in part because of changing climate conditions and decades of fire suppression. Though fire is a natural ecological process in many forest ecosystems, extreme wildfires now pose a growing threat to…
Year Published:
Increasing wildfire activity, decreasing workforce capacity, and growing systemic strain may result in an interagency wildfire-response system less capable of protecting landscapes and communities. Further, increased workloads will likely increase…
Year Published:
Numerous hectares of land are destroyed by wildfires every year, causing harm to the environment, the economy, and the ecology. More than fifty million acres have burned in several states as a result of recent forest fires in the Western United…
Year Published:
Anticipating consequences of disturbance interactions on ecosystem structure and function is a critical management priority as disturbance activity increases with warming climate. Across the Northern Hemisphere, extensive tree mortality from recent…
