We used the FARSITE fire spread simulator to predict the spread of a set of wildfires that occurred in southern Europe. We statistically evaluated the accuracy of FARSITE in predicting the actual fires. We observed a positive effect of the use of customised fuel models vs standard models on simulation accuracy.

Wildfire forecasting tools are needed to improve firefighting operations. An inverse modelling-based system is developed in this paper to predict short-term fire dynamics. The system assimilates airborne infrared images to improve the forward model’s performance. The algorithm is successfully tested with real-scale shrubland fire experiments.

We investigated the main drivers of crown fire by analysing GIS and remote sensing data for 23 bushfires from New South Wales dry forests. Our findings suggest that the influence on crown fire likelihood of weather, fuel levels and slope are not adequately incorporated into current fire behaviour models and fuel management strategies.

WF15162Rapid-response tools and datasets for post-fire remediation: linking remote sensing and process-based hydrological models

An online site provides tools and datasets for the rapid integration of remote sensing observations of burn severity into spatial- and process-based models to aid decision-making activities related to post-fire risk assessment and rehabilitation.

We calculated occurrence rates of 50 bird species in a mixed-conifer forest for 10 years following fire and found that most species (60%) were more abundant in burned than unburned forest, but the positive response to fire was often apparent only under a specific combination of fire severity and time-since-fire parameters.

WF16080Chaparral growth-ring analysis as an indicator of stand biomass development

pp. 1086-1092

We investigated the utility of using shrub growth-ring measurements to estimate annual biomass accumulation in a stand of southern California chaparral from 4 to 11 years after burning. The pattern of biomass accumulation tracked closely with precipitation.

This paper explores acceptability of prescribed burning, livestock grazing and mechanical thinning used to reduce wildland fire risk to life and property, in an Australian context. All were considered acceptable by most survey respondents. Acceptability was associated with social trust, knowledge of fuel management and feeling vulnerable to wildland fire.

Traditional fire management has been used in African landscapes but there is uncertainty in our understanding of its impact on soil carbon and nitrogen. Our study shows that traditional fire management did not affect forest floor or mineral soil carbon and nitrogen pools in a montane forest in southern Ethiopia.

WF15150Faster prediction of wildfire behaviour by physical models through application of proper orthogonal decomposition

Elisa Guelpa, Adriano Sciacovelli, Vittorio Verda and Davide Ascoli

In this paper, proper orthogonal decomposition is applied for the first time to the prediction of fire evolution by physical modelling. The paper shows how this reduction method is able to dramatically reduce the computational cost of physical models without causing the loss of important information.

WF15204Fire severity alters spatio–temporal movements and habitat utilisation by an arboreal marsupial, the mountain brushtail possum (Trichosurus cunninghami)

L. E. Berry, D. B. Lindenmayer, T. E. Dennis, D. A. Driscoll and S. C. Banks

Large wildfires which burn uniformly may have a greater impact on fauna than fires which generate diverse patterns of burnt and unburnt habitat. We found that Possum movement behaviour varied between landscapes which were burnt more evenly than those with diverse burn patterns. The spatial patterns of habitat created by large destructive wildfires can alter the behaviour and ecological relationships of fauna in forest ecosystems.

WF16050Historical reconstructions of California wildfires vary by data source

Alexandra D. Syphard and Jon E. Keeley

A comparison of historical wildfire records in California shows large differences between written and spatial data sources, especially in data completeness. Smaller discrepancies in annual area burned result in cumulatively large differences over time. Different datasets reflect different strengths and weaknesses and these should be considered in any historical analysis.

WF15218Dead organic matter and the dynamics of carbon and greenhouse gas emissions in frequently burnt savannas

Garry D. Cook, , Maëlys Muepu and Adam C. Liedloff

An integrated approach was developed to quantify changes in both dead organic matter and emissions of nitrous oxide and methane with changes in fire regime. A case study in tropical savannas of northern Australia indicated that altered fire management increased carbon stock by more than 3 times the carbon dioxide equivalent change in emissions.

WF16070Curvature effects in the dynamic propagation of wildfires

J. E. Hilton, C. Miller, J. J. Sharples and A. L. Sullivan

Complex interactions between the environment and heat transfer processes can dynamically change the way a fire propagates. In this paper, we parametrise these effects using fire line curvature. Using curvature in a dynamic computational model shows a closer match to experimental fires than models without a curvature parameter.

WF16038Near-term probabilistic forecast of significant wildfire events for the Western United States

Haiganoush K. Preisler, Karin L. Riley, Crystal S. Stonesifer, Dave E. Calkin and W. Matthew Jolly

We present a probabilistic model for forecasting expected number of significant wildfire events for the upcoming week for the Western United States. The procedure may be used to provide daily maps of fire risk with expected number and quantiles of significant fires in each risk category.

WF16072Spatial variability of surface fuels in treated and untreated ponderosa pine forests of the southern Rocky Mountains

Emma Vakili, Chad M. Hoffman, Robert E. Keane, Wade T. Tinkham and Yvette Dickinson

Fuel component semivariance increased with particle diameter regardless of stand condition, with stand-level fuel component loading providing strong predictions (R2 = 0.99). Spatial scales of autocorrelation followed closely (R2 = 0.88) with fuel particle diameter. Incorporating spatial knowledge into fuel sampling will improve fire modelling and wildlife habitat assessments over singular stand-level means.

WF15120Spatial and temporal variations of fire regimes in the Canadian Rocky Mountains and Foothills of southern Alberta

Marie-Pierre Rogeau, Mike D. Flannigan, Brad C. Hawkes, Marc-André Parisien and Rick Arthur

Distinct historical fire regimes with evidence of an anthropogenic influence exist between the Subalpine, Montane and Upper Foothills of southern Alberta. Post-1948 median fire return intervals have departed by up to 223% in the Montane and Foothills, while the Subalpine had a 42% departure in the most rugged region.

WF16020Recovery and adaptation after wildfire on the Colorado Front Range (2010–12)

Miranda H. Mockrin, Susan I. Stewart, Volker C. Radeloff and Roger B. Hammer

Time after wildfire is often discussed as an opportunity for policy change and adaptation, where new regulations and rebuilding can transform the wildland–urban interface, reducing future risk. Our study of recovery post-fire in Colorado found some evidence of adaptation, but also extensive reinvestment in hazard-prone environments, supported by local governments.

WF16016Soil heating during the complete combustion of mega-logs and broadcast burning in central Oregon USA pumice soils

Jane E. Smith, Ariel D. Cowan and Stephen A. Fitzgerald

Extreme soil heating is a concern to forest managers. Temperatures lethal to fine roots and soil organisms were measured beneath combusted mega-logs to at least 10 cm for about seven hours. Soils in a broadcast burn of masticated fuels experienced lethal temperatures in most cases only at the surface for about an hour.

WF15223Visual assessments of fuel loads are poorly related to destructively sampled fuel loads in eucalypt forests

Liubov Volkova, Andrew L. Sullivan, Stephen H. Roxburgh and Christopher J. Weston

Visual assessment of forest fuels is often used to estimate fuel load and predict fire behaviour. More than 500 visual assessments were compared against destructively sampled fuel loads, showing poor correlation between the two and highlighting several serious deficiencies in the operational fuel hazard assessment process.

WF16058Anthropogenic influence on wildfire activity in Alberta, Canada

François-Nicolas Robinne, Marc-André Parisien and Mike Flannigan

We investigated the effect of human development on the area burned in Alberta over a 31-year period. We tested the importance of several human factors. Our results point to a possible ‘ecological frontier’ in which human ignitions increase landscape fire susceptibility in areas where recent industrial expansion and forested wildlands overlap.
