WF17109Sleep in wildland firefighters: what do we know and why does it matter?

Grace E. Vincent, Brad Aisbett, Alexander Wolkow, Sarah M. Jay, Nicola D. Ridgers and Sally A. Ferguson
pp. 73-84

This paper reviews firefighters’ sleep during wildfire operations, the operational and environmental factors that impact on sleep, and how sleep affects health and safety. For fire agencies to support firefighting personnel, strategies are needed to improve and manage firefighters’ sleep, and reduce any adverse impacts on firefighters’ work.

WF17114How do weather and terrain contribute to firefighter entrapments in Australia?

Sebastien Lahaye, Jason Sharples, Stuart Matthews, Simon Heemstra, Owen Price and Rachel Badlan
pp. 85-98

Firefighters are occasionally entrapped by wildfires. This paper presents an analysis of incidents in Australia over the last 40 years, and reveals the main contributing factors to those entrapments. The effect of a wind change on fire spread direction was found to be the principal cause of fatal fire entrapments.

WF17030A comparison of the US National Fire Danger Rating System (NFDRS) with recorded fire occurrence and final fire size

Nicholas G. Walding, Hywel T. P. Williams, Scott McGarvie and Claire M. Belcher
pp. 99-113

An analysis of the National Fire Danger Rating System for the conterminous US (2006–13). Fire danger indices are correlated with measures of fire activity in order to identify spatial patterns and discrepancies across the US and identify different aspects of wildfire activity along several fire danger spectrums.

This study provides information on how post-fire surface fuel loadings change within the first 9 years after forest wildfires in dry conifer and hardwood forests of California. Differences in post-fire surface fuel dynamics among fire severity classes – low, moderate and high – are identified.

WF17095Soil organic layer combustion in boreal black spruce and jack pine stands of the Northwest Territories, Canada

pp. 125-134

In this study, we assess soil organic layer (SOL) combustion in the Taiga Plains and Taiga Shield ecozones of the Northwest Territories, Canada, within the unprecedentedly large area burned by fires in 2014. We provide models and calibrations that should allow future research to more accurately estimate SOL burn depth in black spruce and jack pine boreal forests.

This proof-of-concept experiment uses distributed temperature sensing (DTS) to measure soil temperatures during a managed fire. Using off-the-shelf 242-μm diameter fibre, we were able to collect temperature data every 20 s over a 5.5-h period at 1243 locations along 316 m length of fibre with a spatial resolution of 60 cm.

WF17049An analysis of the effect of aspect and vegetation type on fine fuel moisture content in eucalypt forest

Alen Slijepcevic, Wendy R. Anderson, Stuart Matthews and David H. Anderson

The effect of aspect and vegetation structure on the fine fuel moisture content of different fuel strata was investigated. The effect of the percentage of fuel available for burning and when top litter moisture content fell into categories associated with severe fire behaviour and fire management planning was further discussed.
