Surface fuel information is an essential input for models of fire behaviour and fire effects. However, spatially explicit, continuous information on surface fuel loads and fuelbed depth is scarce because the collection of field data is laborious,…

Background: Medical services for wildland fire incidents are vital and fire personnel need to be comfortable seeking care and have adequate access to care.
Aims: The aim of this study was to examine wildland firefighters’ (WLFFs) attitudes towards,…

Lodgepole pine (Pinus contorta var. latifolia) has a reputation for indestructibility, but recent events in the Southern Rockies may have pushed even this stalwart species to the edge. Research by Rocky Mountain Research Station (RMRS) scientist…
Year Published:
During a wildland fire event, firefighters often receive significant exposure to smoke consisting of particulate matter (PM) and gaseous emissions. Major respiratory and cardiovascular health concerns are related to inhalation of smoke and…

1. Animal ecology and evolution are shaped by environmental perturbations, which are undergoing unprecedented alterations due to climate change. Fire is one such perturbation that causes significant disruption by causing mortality and altering…

Background: Current guidance for implementation of United States federal wildland fire policy charges agencies with restoring and maintaining fire-adapted ecosystems while limiting the extent of wildfires that threaten life and property, weighed…
Year Published:
Fire management is growing increasingly complex in an environment beset by climate change, an ever-growing wildland-urban interface, and difficulties developing and maintaining workforce capacity. Delivery of timely and relevant fire science to…
Year Published:
High-severity wildfires create pulses of snags that serve a variety of functions as they decompose over time. Snag-related benefits (and hazards) are often linked to specific decomposition stages, but snag decomposition rates and pathways are not…
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:
An atmospheric river (AR) is a strong filamentary water vapor transport that plays a critical role in regional hydroclimate systems. While climate conditions can affect wildfire activities, the process by which ARs are associated with wildfire…
Year Published:
Large outdoor fires such as wildfires, wildland urban interface (WUI) fires, urban fires, and informal settlement fires have received increased attention in recent years. In order to develop effective emergency plans to protect people from threats…
Year Published:
Fire regimes are changing dramatically worldwide due to climate change, habitat conversion, and the suppression of Indigenous landscape management. Although there has been extensive work on plant responses to fire, including their adaptations to…
Year Published:
Burn severity is commonly assessed using Burn Ratios and field measurements to provide land managers with estimates of the degree of burning in an area. However, less commonly studied is the ability of spectral indices and Burn Ratios to estimate…
Year Published:
Firebrands generated from wildfires can contribute to wildfire spread and are a threat to structures in the wildland-urban interface (WUI). Understanding the characteristics such as the firebrand size, mass and heat flux to the recipient fuel are…
Year Published:
High-severity fires and short-interval reburns strongly influence forest structure and composition and may overwhelm forest ecosystem resilience and catalyze persistent shifts to non-forest conditions. Recent increases in annual area burned and…
Year Published:
Sagebrush ecosystems in the United States have been declining since EuroAmerican settlement, largely due to agricultural and urban development, invasive species, and altered fire regimes, resulting in loss of biodiversity and wildlife habitat. To…
Year Published:
Historical logging practices and fire exclusion have reduced the proportion of pine in mixed-conifer forests of the western United States. To better understand pine’s decline, we investigate the impact of historical logging on the tree regeneration…
Year Published:
Fire regimes are a major agent of evolution in terrestrial animals. Changing fire regimes and the capacity for rapid evolution in wild animal populations suggests the potential for rapid, fire-driven adaptive animal evolution in the Pyrocene. Fire…
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…
