The contributions of wildland fire researchers that focus on increasing firefighter safety may fall short of potential owing to a lack of translation of peer-reviewed results. We use a case study to examine how primary research is – and could be better – transferred to fire managers, policy-makers and firefighters through four core communication theories (diffusion, translation, discourse and media richness).

WF16100Sharing contracted resources for fire suppression: engine dispatch in the Northwestern United States

Katie M. Lyon, Heidi R. Huber-Stearns, Cassandra Moseley, Christopher Bone and Nathan A. Mosurinjohn
pp. 113-121

We examined private engine dispatch patterns in the Northwest USA from 2008 to 2015. We found that contracted engines were used more often and more intensively over the 8-year period. However, in 2015, only 71% of listed engines were utilised at peak demand during one of the largest fire seasons in the Northwest, even though post-fire reports noted a lack of available engines.

WF15213Spatial distribution and temporal variability of open fire in China

Kunpeng Yi, Yulong Bao and Jiquan Zhang
pp. 122-135

This study presents considerable information about the regional nature of fire and outdoor fire regimes in China. During the period 2001–12, an average area of 3.2 × 106 ha per year burnt in China. The majority of fires in China occurred in the north-eastern and south-western provinces.

Combining tree ages with fire-scar data enables spatial modelling of historical mixed-severity fire regimes. Sensitivity analyses showed that: (1) tree-age data refine modelled fire boundaries without biasing mean fire return intervals; and (2) using fixed rather than variable thresholds produces more consistent, ecologically representative results.

WF16143Has canopy height and biomass recovered 78 years after an intense fire in south-western Australia's red tingle (Eucalyptus jacksonii) forests?

pp. 148-155

Canopy height and biomass has not recovered to pre-fire levels in Eucalyptus jacksonii forest 78 years after an intense crown fire (1937) near Nornalup, south-western Australia. The effects of the intense fire and a warming, drying trend may have prevented recovery of forest height and structure despite regeneration from seed and prolific epicormic shoot production. Venerable trees are high priorities for conservation attention under climate change.

Rock rose, a very flammable plant, forms dense shrublands in Mediterranean wildlands that are rapidly expanding on abandoned oligotrophic soils, thus increasing fire hazard. We found that soil fertilisation can be a key tool in reducing wildfire hazards by hindering the re-establishment of new rock rose seedlings after fire and improving the grazing value of the shrublands in both burned and unburned area.

In this work, we evaluated how well the hourly Fine Fuel Moisture Code (FFMC) could predict the dead fine fuel moisture content of three different forest stands under different conditions of shelter and seasons in the south-eastern Great Xing’an Mountains, which will contribute to the control efforts of forest fire in this region.

WF16108Spatially varying constraints of human-caused fire occurrence in British Columbia, Canada

Philip E. Camp and Meg A. Krawchuk

The relative importance of different drivers of human-caused fire can vary based on levels of human footprint and biophysical characteristics of a study region. We show that human-caused fire occurrence in areas with substantial human footprint are controlled by a different set of variables than in remote areas.

WF16026Spatial distribution of grassland fires at the regional scale based on the MODIS active fire products

Zhengxiang Zhang, Zhiqiang Feng, Hongyan Zhang, Jianjun Zhao, Shan Yu and Wala Du

This study used kernel density estimation to analyse the spatial pattern of grassland fires based on the MODIS active fire product and to define grassland fire risk zones. The results show that the kernel density estimation method can be applied to analyse the spatial distribution of grassland fires.

WF16106Hillslope-scale prediction of terrain and forest canopy effects on temperature and near-surface soil moisture deficit

Sean F. Walsh, Petter Nyman, Gary J. Sheridan, Craig C. Baillie, Kevin G. Tolhurst and Thomas J. Duff

Fire managers often use a drought index at coarse spatial resolution to determine soil moisture status in flammable forests. In complex terrain, there is a fine-scale mosaic of near-surface soil moisture deficit that may create important constraints on prescribed burning operations. A simple method is proposed for predicting this pattern.

WF16135An empirical machine learning method for predicting potential fire control locations for pre-fire planning and operational fire management

Christopher D. O' Connor, David E. Calkin and Matthew P. Thompson

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.

WF16118Variability and drivers of extreme fire weather in fire-prone areas of south-eastern Australia

Sarah Harris, Graham Mills and Timothy Brown

We identify the most extreme fire weather days based on McArthur’s Forest Fire Danger Index (FFDI) for 24 sites across south-eastern Australia for potential use in fire risk planning. The extent and variability of these highest FFDI days are analysed by the contributions of temperature, relative humidity, wind speed, wind direction and drought indices.

WF16073A simulation and optimisation procedure to model daily suppression resource transfers during a fire season in Colorado

Yu Wei, Erin J. Belval, Matthew P. Thompson, Dave E. Calkin and Crystal S. Stonesifer

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.
