Historical fire–climate relationships suggest three fire regimes: flammability-limited, fuel-limited and ignition-limited ecosystems. In the first, annual burning is limited by seasonal climates; in the second, by climate factors that affect herbaceous fuel production; and in the third, the patterns are more strongly controlled with human ignitions than with annual variations in climate.

WF16165Climatic influences on interannual variability in regional burn severity across western US forests
Interannual variability in burn severity across forested regions of the western United States is found to be weakly to moderately correlated with fuel aridity, moisture stress and burned area extent. These results suggest that increased fuel aridity resulting from anthropogenic climate change will increase burn severity in western US forests.
WF16056Understanding forest fire patterns and risk in Nepal using remote sensing, geographic information system and historical fire data
Historical wildfire occurrences were mapped using remotely sensed data to analyse the spatial and temporal patterns of forest fires in Nepal since 2000. These data were supplemented with a modelling procedure to compute and map fire risk within Nepal’s 75 districts. The risk maps will potentially aid firefighting authorities to allocate limited resources to areas where the potential fire risk is highest.
WF16152Spatial scales influence long-term response of herbivores to prescribed burning in a savanna ecosystem
In savanna ecosystems, recently burned areas attract large number of herbivores, but we know little about how long such attractiveness may persist. By monitoring herbivores’ visitation of burns over a period of 6 years, we found that long-term preference for the burns varied predictably depending on the herbivore species and the spatial scale (extent and grain) of the burn. These results highlight the importance of considering spatial scales in implementing fire prescriptions.
WF16128Emissions of forest floor and mineral soil carbon, nitrogen and mercury pools and relationships with fire severity for the Pagami Creek Fire in the Boreal Forest of northern Minnesota
Forest fires are a major source of C, N (important greenhouse gases) and Hg (important pollutant) to the atmosphere. Using a new remote sensing scaling approach, we found that >90% of those elements in the forest floor were emitted to the atmosphere during a wildfire in northern Minnesota.
WF16177Charcoal reflectance suggests heating duration and fuel moisture affected burn severity in four Alaskan tundra wildfires
For the first time, we have coupled the use of field observations of burn severity with charcoal reflectance for four tussock–shrub Alaskan tundra wildfires. Reflectance results suggest that heating durations were broadly similar across the burns and microsite variations in burn severity were due to local variations in fuel moisture.
We predict firebrand transport and landing position using a transport model that explicitly includes plume turbulence. The in-plume turbulence largely determines the spread in landing position, and also approximately doubles the maximum spotting distance compared with that in a plume without turbulence. These results provide a pathway to better parametrisation of firebrand transport.
A coupled atmosphere–fire model was used to investigate the dynamic fire spread that occurs when two firelines merge at an oblique angle. The results agree qualitatively with a previous experimental study, and give insight into the pyro-convective processes that help drive this form of dynamic fire behaviour.

WF16081Higher sensitivity and lower specificity in post-fire mortality model validation of 11 western US tree species
This study uses an independent dataset from prescribed fire monitoring plots to validate a commonly used post-fire tree mortality model. Findings indicate that model performance was generally good but tended to consistently overpredict mortality in thin-barked species and size classes. Overpredicting mortality may have the unintended consequence of not meeting desired reductions in small tree density that is a common goal with prescribed fire treatments.
We review challenges to determining and demonstrating efficiency of strategic approaches to managing low-probability, high-consequence large fire events. Key knowledge gaps relate to quantifying the consequences of fire and how they may change under alternative suppression strategies.
Patch mosaic burning aims to create landscape mosaics of varying fire ages to cater for the needs of a diversity of species, but empirical studies often fail to support this notion. Mosaics of other fire regime components such as fire frequency are thought to be important but their effects have not been tested empirically. We present empirical evidence that fly and wasp species richness responds to both kinds of fire mosaic.
WF16154Air quality policy and fire management responses addressing smoke from wildland fires in the United States and Australia
This paper presents a review of air quality and smoke management policies in the United States with comparisons with Australia. It discusses how the air quality regulatory framework affects wildland fire management. To be most effective, the smoke regulatory framework and fire management policy must keep pace with scientific advances as well as environmental and social change.
An eastern United States wildfire hazard model updated with finer-resolution drought occurrence data is evaluated to determine if information is gained from the more detailed data. Inclusion of newer drought data shifted its contribution among monthly models to wildland–urban interface information. This refinement has removed the influence of climate division data.
WF16124Federal fire managers' perceptions of the importance, scarcity and substitutability of suppression resources
United States fire managers were surveyed to assess the operational perception of three key suppression resource themes: importance, scarcity and substitutability.
WF16135An empirical machine learning method for predicting potential fire control locations for pre-fire planning and operational fire management
This research supports planning for and management of wildfires to improve resource allocation decisions and to reduce risk to fire responders. We use historical fire perimeters to identify landscape features and conditions associated with where fires stop, and leverage these relationships to predict potential future fire control locations.
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.
