Fatigue in wildland firefighting: relationships between sleep, shift characteristics, and cognitive function
Year: 2025
BackgroundWildland firefighting requires exposure to long shifts and poor sleep, which may pose a risk to worker safety due to impaired cognitive function.AimsWe investigated the associations between sleep, shift characteristics, and cognitive function in wildland firefighters.MethodsWe conducted a within-subject observational study with 25 wildland firefighters from the British Columbia Wildfire Service, Canada. Data were collected remotely during the 2021 and 2022 fire seasons. Wrist-worn actigraphy and the psychomotor vigilance task served…

Impact of wildfire smoke, heat stress and sleep deprivation on the brain health of wildland firefighters
Year: 2025
Wildland firefighters (WLFFs) face significant brain health risks due to prolonged exposure to smoke, extreme heat, dehydration, physical exertion and irregular sleep patterns. Here, the literature is presented as a narrative review on studies that inform our knowledge on WLFF brain health. The neurotoxic components of wildfire smoke, such as particulate matter, carbon monoxide and polycyclic aromatic hydrocarbons, can disrupt brain function by inducing oxidative stress, neuroinflammation and hypoxia, which can contribute to cognitive decline and increase the risk of neurodegenerative…

Wildland firefighter exposure and female cancer risk: currently available evidence
Year: 2025
The James M. Inhofe National Defence Authorization Act for Fiscal Year 2023 established that certain illnesses and diseases are to be deemed as proximately caused by employment in federal fire protection activities. However, cancers affecting female wildland firefighters were not included on this list and are recommended for further evaluation. We present the best available scientific evidence for the risk of breast and gynaecological cancers associated with exposures that are commonly measured in the wildland fire environment, including benzene, polycyclic aromatic hydrocarbons, and…

Fire Without Borders: Observations, Experiences, and Lessons Learned from the 36-Pit Fire
Year: 2015
The 36-Pit fire near Estacada, OR broke out on September 13, 2014 and spread quickly, burning a total of 5,524 acres. The fire started by a target shooting accident in the 36 Pit quarry. Conditions were very hot and dry when the fire broke out, with temperatures ranging from the upper 80s to the mid-90s, and the relative humidity around 34%. In addition, there were 30 mph winds blowing from the east through the Clackamas River canyon...

Using Prescribed Fire as a Management Strategy in the Turnbull NWR
Year: 2015
Management strategies developed for Turnbull NWR call for the integration of a variety of techniques to restore natural stand conditions, reduce hazard fuels and improve wildlife habitat. These strategies include various types of thinning followed by the application of prescribed fire. On April 14, 2015 the NW Fire Science Consortium sponsored a technical field tour to the refuge led by Mike Rule, refuge wildlife biologist, and Doug Frederick, Assistant Fire Management Officer. The tour included five stops; starting at the Headquarters for an overview of the refuge and discussion on…

Restoring & Managing Mixed Conifer Forests in the PNW
Year: 2013
Many collaborative groups working across the eastside of Oregon and Washington have developed good working agreements on treatments appropriate for ponderosa pine forest types. These groups are actively supporting and helping to develop projects that will meet ecological objectives for dry forests while generating jobs and economic activity in local communities. Currently, there is less agreement on how to approach restoration and management of mixed-conifer forests, in large part because there does not appear to be a comparable scientific consensus as that which exists for ponderosa pine…

Management of Cheatgrass Fuel Loading in the Shrub-Steppe
Year: 2013
The Columbia Basin Natural Wildlife Refuge (CNWR) had been periodically grazed until the Refuge was established in 1944. Cheatgrass became a prominent plant in the area. In 1986 a fire occurred near the study area. The area was reseeded with Elymus wawawaiensis (Snake River Wheatgrass, Secar cultivar). This grass has established reducing cheatgrass cover to very low levels. The study area was established in 2002 to test hypotheses on the effects of herbicides on plant community structure and establishment of Elymus wawawaiensis. In 2002 study plots were established and characterized before…

Pole Creek Fire
Year: 2012
In September 9, 2012 a lightning strike hit the Pole Creek trailhead in the Deschutes National Forest, approximately 8 miles southwest of Sisters, Oregon. The wildfire was contained on October 17th after spreading over 26,000 acres of timber and brush. In response to this event, the Northwest Fire Science Consortium partnered with Oregon State University (OSU) College of Forestry, OSU Forestry & Natural Resources Extension, USFS Region 6, and the Central Oregon Fire Management Service to offer an opportunity for in-the-field learning in the immediate post-fire environment. Targeted…
