We analysed wildfires from 1984 to 2012 in eight mountainous ecoregions to determine if recent climate-driven increases in burning extended to alpine treeline ecotones. Little alpine vegetation burned, but in four of eight regions, the proportion of area burned in subalpine parkland was similar to or greater than that in the larger landscape.
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.
WF16003Fire spread from MODIS burned area data: obtaining fire dynamics information for every single fire
A new strategy to derive detailed fire spread information from satellite imagery across large areas is proposed. Single fires are identified and described with respect to the timing and location of their ignition. The daily directional spread information of the fire events is also recorded during this process.
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.
WF15218Dead organic matter and the dynamics of carbon and greenhouse gas emissions in frequently burnt savannas
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.
WF16052Relationships between fire severity and recruitment in arid grassland dominated by the obligate-seeding soft spinifex (Triodia pungens)
Relationships between fire severity and plant recruitment processes in arid zone biomes are poorly understood. We examined recruitment following high- and low-severity fires in arid grassland dominated by the obligate-seeding Triodia pungens (soft spinifex), and found variable responses among species. Our results indicate that modelling plant responses to fire severity requires species-specific information on traits such as germination biologies, seedbank processes and lethal temperature thresholds of seeds.
WF16085Seed tolerance to heating is better predicted by seed dormancy than by habitat type in Neotropical savanna grasses
We investigated whether seed tolerance to high temperatures was related to dormancy type and habitat type for grass species from Brazilian fire-prone savannas. We found that seeds from wetter habitats had low tolerance whereas dormant seeds had high tolerance to heat shock, suggesting both dormancy level and habitat moisture contribute to the evolution of seed tolerance to heat.
WF16105Recently but infrequently burnt breeding sites are favoured by threatened Gouldian finches (Erythrura gouldiae)
Changed fire regimes, with larger and more frequent fires, are a potential cause of Gouldian finch population declines. Gouldian finches chose infrequently burnt breeding sites that were burnt in the previous fire season. Patchy grass seed availability, caused by frequent landscape fires, may influence finch decline.
WF15204Fire severity alters spatio–temporal movements and habitat utilisation by an arboreal marsupial, the mountain brushtail possum (Trichosurus cunninghami)
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.

WF16064How a risk focus in emergency management can restrict community resilience – a case study from Victoria, Australia
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.
WF15122Assessing the potential of the differenced Normalized Burn Ratio (dNBR) for estimating burn severity in eastern Canadian boreal forests
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.
WF16073A simulation and optimisation procedure to model daily suppression resource transfers during a fire season in Colorado
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.
