WF10129 A review of operations research methods applicable to wildfire management

James P. Minas, John W. Hearne and John W. Handmer
pp. 189-196

Wildfire managers operate in a highly challenging decision environment characterised by complexity, multiple conflicting objectives and uncertainty. Operations research (OR) is a discipline that uses analytical techniques to aid decision-making in complex systems. This paper discusses a range of OR methods available to assist wildfire managers, with illustrative examples drawn from the wildfire and disaster OR literature.

WF10148 Fire management on private conservation lands: knowledge, perceptions and actions of landholders in eastern Australia

pp. 197-209

Conservation efforts on private land contribute to minimising biodiversity loss. These efforts also include maintaining ecological processes, such as fire. Fire management is complex and private landholders must balance conservation efforts with risks to life and property. Our research shows that fire is poorly understood potentially compromising management effectiveness.

Containment times of fires with aerial suppression were compared with estimated containment times for the same fires without aerial suppression. Fire managers believe that aircraft reduce time to containment when firefighting conditions are challenging owing to fuel hazard rating, weather conditions, ground response times and area burning at initial attack.

WF10075 Assessment of post-fire changes in land surface temperature and surface albedo, and their relation with fire–burn severity using multitemporal MODIS imagery

Sander Veraverbeke, Willem W. Verstraeten, Stefaan Lhermitte, Ruben Van De Kerchove and Rudi Goossens
pp. 243-256

This paper assesses post-fire changes in land surface temperature (LST) and surface albedo (α) using remotely sensed time series Lag, i.e. time since fire, and seasonal timing affected the magnitude of post-fire changes. Moreover, the seasonality constrains the suitability of the LST and α layers as indicators of fire severity and burn severity.

WF11024 Monitoring live fuel moisture content of heathland, shrubland and sclerophyll forest in south-eastern Australia using MODIS data

G. Caccamo, L. A. Chisholm, R. A. Bradstock, M. L. Puotinen and B. G. Pippen
pp. 257-269

This study evaluates the potential of MODIS-derived spectral indices to predict live fuel moisture content of three different fire-prone vegetation types (i.e. shrubland, heathland and sclerophyll forest) in the Sydney Basin Bioregion (Australia).

WF10127 Flame temperature and residence time of fires in dry eucalypt forest

B. Mike Wotton, James S. Gould, W. Lachlan McCaw, N. Phillip Cheney and Stephen W. Taylor
pp. 270-281

Flame temperature profiles and flame-front residence times were measured from a series of experimental fires in dry eucalypt forest of different fuel age and structure. A method to estimate flame temperature at any height within the flame was developed. Average flame-front residence time for eucalypt forest fuels was 37 s.

WF10055 Wind–terrain effects on the propagation of wildfires in rugged terrain: fire channelling

Jason J. Sharples, Richard H. D. McRae and Stephen R. Wilkes
pp. 282-296

This paper considers an atypical form of fire propagation, characterised by rapid lateral spread, and associated spot-fire development, across steep, lee-facing slopes. The role of wind, terrain and fire interaction in driving the phenomenon is investigated using weather, elevation and multispectral fire data and a likely explanation for the atypical spread is hypothesised.

Fire history mapping for 1990–2009 is used to quantify the mitigation of late dry-season wildfire (LDS) through prescribed burning in Western Arnhem Land. Prescribed burning can substantially reduce LDS area, by direct one-to-one replacement. A management program operating since 2005 has successfully reduced LDS using prescribed fire.

WF11019 Fuel loadings 5 years after a bark beetle outbreak in south-western USA ponderosa pine forests

Chad M. Hoffman, Carolyn Hull Sieg, Joel D. McMillin and Peter Z. Fulé
pp. 306-312

South-western ponderosa pine stands attacked by bark beetles had higher tree densities compared to stands not attacked. Five years post-outbreak, after adjusting for differences in pre-outbreak tree density, attacked stands had lower tree densities and lower canopy fuel loadings, but higher surface fuel loadings than stands that were not attacked.
