The research investigated different understandings of risk and resilience in emergency management. Findings indicate that uncertainty tends to be framed as knowable risk. Resilience consequently appears as the product of risk reduction and response. We argue that this limited understanding affects people’s ability to know their risk, make decisions and, therefore, be resilient.

This paper presents a probabilistic model for predicting house damage due to wildfire at the mesoscale. The model is based on Bayesian networks (BN), and its inputs are readily available spatiotemporal datasets. The BN is coupled with a GIS for a spatially explicit estimate of expected house damages. Numerical investigations are carried out for Cyprus.

This work showed that the use of Landsat satellite imagery through the differenced Normalized Burn Ratio (dNBR) index provides a valuable approach for the quantification and mapping of burn severity in eastern boreal forests of Canada, which is useful in post-fire ecology research and management.

Charcoal was collected from mosses and traps after a wildfire in NE China. Although both macroscopic and microscopic charcoals were found to have been dispersed across long distances, their concentrations clearly distinguished burnt areas from unburnt areas. The burnt area and the vegetation were major factors in determining charcoal abundances.

The ignition of natural fuels by hot metal particles from powerlines and welding may initiate wildfires. In this work, we measured the minimum particle temperature required to ignite pine needles for variable particle sizes and fuel moisture contents. We provide a theory to explain the critical ignition conditions and ignition delay time.

WF16077Effects of fire radiative energy density dose on Pinus contorta and Larix occidentalis seedling physiology and mortality

pp. 82-94

Through controlled nursery and combustion laboratory experiments we show that increased doses of fire radiative energy density can lead to potential mortality or reduced vigour in surviving seedlings. Doses required to sustain or eliminate two woody species are identified. Seedling physiological responses and mortality change with increasing doses of fire radiative energy density.

WF16139Impacts of fire radiative flux on mature Pinus ponderosa growth and vulnerability to secondary mortality agents

pp. 95-106

Through stand-scale prescribed fires, we demonstrate that fire radiative flux has a dose–response relationship with Pinus ponderosa growth post-fire. Generally, as dose of fire radiative flux increased, post-fire radial growth decreased. We also show that tree resin duct defences are increased, regardless of fire intensity.

WF16143Has canopy height and biomass recovered 78 years after an intense fire in south-western Australia's red tingle (Eucalyptus jacksonii) forests?

Grant Wardell-Johnson, Liam Crellin, Casey Napier, Garrett Meigs, Alyssa Stevenson and Su Ing Wong

Canopy height and biomass has not recovered to pre-fire levels in Eucalyptus jacksonii forest 78 years after an intense crown fire (1937) near Nornalup, south-western Australia. The effects of the intense fire and a warming, drying trend may have prevented recovery of forest height and structure despite regeneration from seed and prolific epicormic shoot production. Venerable trees are high priorities for conservation attention under climate change.

WF15213Spatial distribution and temporal variability of open fire in China

Kunpeng Yi, Yulong Bao and Jiquan Zhang

This study presents considerable information about the regional nature of fire and outdoor fire regimes in China. During the period 2001–12, an average area of 3.2 × 106 ha per year burnt in China. The majority of fires in China occurred in the north-eastern and south-western provinces.

WF16073A simulation and optimisation procedure to model daily suppression resource transfers during a fire season in Colorado

Yu Wei, Erin J. Belval, Matthew P. Thompson, Dave E. Calkin and Crystal S. Stonesifer

We developed and implemented a model to improve engine and crew assignments and transfers during a fire season. We implemented this model to study how multiple factors may influence engine and crew transfer costs and efficiencies. Results show we could decrease engine and crew transport costs through efficient resource dispatching.
