WF14117Advances in remote sensing and GIS applications in support of forest fire management

Ioannis Z. Gitas, Jesús San-Miguel-Ayanz, Emilio Chuvieco and Andrea Camia
pp. 603-605

This foreword describes advances and challenges for the use of remote sensing and geographic information systems in the operational monitoring and management of wildland fires at local, regional and global scales since the 1970s. Selected articles using remote sensing in different phases of wildland fire management are highlighted.

WF12052Integrating geospatial information into fire risk assessment

E. Chuvieco, I. Aguado, S. Jurdao, M. L. Pettinari, M. Yebra, J. Salas, S. Hantson, J. de la Riva, P. Ibarra, M. Rodrigues, M. Echeverría, D. Azqueta, M. V. Román, A. Bastarrika, S. Martínez, C. Recondo, E. Zapico and F. J. Martínez-Vega
pp. 606-619

This paper presents a method to generate fire risk maps making extensive use of geographic information technologies. It describes how the variables were generated and integrated, and how the final index was validated using 2 years of fire occurrence.

WF12053Assessment of fire selectivity in relation to land cover and topography: a comparison between Southern European countries

Sandra Oliveira, Francisco Moreira, Roberto Boca, Jesús San-Miguel-Ayanz and José M. C. Pereira
pp. 620-630

This study investigates the selectivity of fire in relation to land cover type and topography in Southern Europe. Shrubland and grassland are more fire prone, whereas agricultural areas and artificial surfaces are less susceptible to burn. There are significant differences between countries and regions. Slopes >25% and north facing ones were less fire prone.

WF12137Development and mapping of fuel characteristics and associated fire potentials for South America

M. Lucrecia Pettinari, Roger D. Ottmar, Susan J. Prichard, Anne G. Andreu and Emilio Chuvieco
pp. 643-654

This research proposes a process to generate a fuel map for large areas, using the Fuel Characteristic Classification System. Fuelbeds were built to represent fuels across the continent of South America. Fire potentials including indexed values of surface fire behaviour, crown fire and available fuels were computed and mapped, enabling users to assess fire hazard, predict fire behaviour and calculate fuel consumption and greenhouse gas emissions.

WF13015Mapping the daily progression of large wildland fires using MODIS active fire data

Sander Veraverbeke, Fernando Sedano, Simon J. Hook, James T. Randerson, Yufang Jin and Brendan M. Rogers
pp. 655-667

We developed an approach to derive continuous maps of daily fire progression using Moderate Resolution Imaging Spectroradiometer (MODIS) active fire and thermal anomaly data. The method outperformed the temporal reporting accuracy of two MODIS burnt area products. Remote sensing data on fire progression have the potential to improve our understanding of climate and vegetation controls on fire behaviour and emissions.

WF12055Trend analysis of medium- and coarse-resolution time series image data for burned area mapping in a Mediterranean ecosystem

Thomas Katagis, Ioannis Z. Gitas, Pericles Toukiloglou, Sander Veraverbeke and Rudi Goossens
pp. 668-677

Time series of low-resolution satellite imagery were analysed with the use of the Breaks for Additive Seasonal and Trend (BFAST) method. Trend changes were identified after a fire event in southern Greece, resulting in the mapping of the burned area and illustration of the post-fire vegetation recovery trend.

WF13042Use of night vision goggles for aerial forest fire detection

L. Tomkins, T. Benzeroual, A. Milner, J. E. Zacher, M. Ballagh, R. S. McAlpine, T. Doig, S. Jennings, G. Craig and R. S. Allison
pp. 678-685

Two sets of flight trials explored the potential of night vision aids in aerial wildfire detection. One was a controlled experiment and the other part of operational aerial detection patrols. Small fires could be detected and reliably discriminated using night vision goggles from distances compatible with daytime aerial detection patrols.

WF13089Modern fire regime resembles historical fire regime in a ponderosa pine forest on Native American lands

Amanda B. Stan, Peter Z. Fulé, Kathryn B. Ireland and Jamie S. Sanderlin
pp. 686-697

We studied the surface fire regime in a forest on tribal lands where prescribed burning has occurred since the 1960s. Fire frequency and synchrony were similar, but fire seasonality was dissimilar, between the historical and modern land-use periods. Fuels, climate and human land uses regulated the fire regime over time.

WF13080Numerical prediction of size, mass, temperature and trajectory of cylindrical wind-driven firebrands

Luis A. Oliveira, António G. Lopes, Bantwal R. Baliga, Miguel Almeida and Domingos X. Viegas
pp. 698-708

Mathematical models of the trajectory, oscillations, rotation, and mass and size time-evolution of cylindrical wind-driven firebrands are proposed. The total distance travelled by the firebrand is an increasing function of its initial aspect ratio. Particle initial orientation relative to the wind, and its oscillation, significantly influence its trajectory.

WF13084Equilibrium moisture content and timelag of dead Pinus pinaster needles

Sérgio Lopes, Domingos Xavier Viegas, Luís Teixeira de Lemos and Maria Teresa Viegas
pp. 721-732

This study aims to improve fine fuel moisture content prediction below fibre saturation of Pinus pinaster dead needles through modelling of sorption processes and equilibrium moisture content. Good fit between the results of combinations of models and laboratory and field measurements was obtained.

WF13159The temporal evolution of wildfire ash and implications for post-fire infiltration

Victoria N. Balfour, Stefan H. Doerr and Peter R. Robichaud
pp. 733-745

Ash crust formation can occur following severe wildfire events. Initial ash composition and a hydrating rainfall event are necessary precursors for crust formation. An ash crust can decrease ash hydraulic conductivity by 1 order of magnitude as well as significantly decrease ash layer porosity and increase bulk density.

We quantified the winter and spring diet of silky mice (Pseudomys apodemoides) and heath rats (P. shortridgei) at sites ranging from 2 to 55 years post fire. Silky mice ate different foods at very recently burnt and mature forest sites whereas heath rats ate similar foods across the time-since-fire spectrum.
