WF23128Resurfacing of underground peat fire: smouldering transition to flaming wildfire on litter surface

Yichao Zhang, Yang Shu, Yunzhu Qin 0000-0001-9704-8630, Yuying Chen, Shaorun Lin 0000-0003-4090-1148, Xinyan Huang 0000-0002-0584-8452 and Mei Zhou
 

Photos of smoke emerging from smouldering peat and of flames burning surface litter layer after underground peat fire has resurfaced

Smouldering peat fires can survive underground for months, and may re-emerge and start a flame above ground when the dry and hot season arrives. This work demonstrates that the resurfacing of underground peat fire can ignite a flame on the surface litter layer and increase wildfire hazards. Photograph by Yichao Zhang et al.

WF23094Impacts of changing fire regimes on hollow-bearing trees in south-eastern Australia

Philip Gibbons, Dejan Stojanovic, David B. Lindenmayer and Giselle Owens
 

Fire frequency is increasing with climate change in south-eastern Australia. We predicted that hollow-bearing trees will decline in forests where frequent fires co-occur with high rates at which trees collapse or are removed (e.g. due to frequent planned burns or timber harvesting) and/or where there are not a sufficient number of suitable mature trees in which new hollows can be excavated by fire (e.g. where tree regeneration is inhibited).

WF23098Spatial and temporal opportunities for forest resilience promoted by burn severity attenuation across a productivity gradient in north western Patagonia

Florencia Tiribelli 0000-0003-4746-1704, Juan Paritsis, Iván Barberá and Thomas Kitzberger
 

Burn severity is critical to understand fire dynamics. We mapped and modelled burn severity as a function of biophysical variables. Low severity was rare and occurred in small fires during cool and wet summer conditions in areas with sparser fuels or in more productive environments with discontinuous wet fuels.

WF23133Ingesting GOES-16 fire radiative power retrievals into Warn-on-Forecast System for Smoke (WoFS-Smoke)

Thomas Jones 0000-0002-4966-5041, Ravan Ahmadov, Eric James, Gabriel Pereira, Saulo Freitas and Georg Grell
 

This work used high frequency satellite derived wildfire properties to improve short-term (0–6 h) forecasts of smoke plumes. Results show that ingesting high frequency data significantly improves wildfire smoke forecasts compared to current operational systems.

WF23042BARA: cellular automata simulation of multidimensional smouldering in peat with horizontally varying moisture contents

Dwi M. J. Purnomo, Eirik G. Christensen, Nieves Fernandez-Anez and Guillermo Rein 0000-0001-7207-2685
 

This paper presents a cellular automaton to simulate multidimensional spread of smouldering peat with horizontally varying moisture. The model accurately predicted laboratory experiments (below 20% error) on the spread of smouldering under non-uniform moisture conditions and reproduced complex phenomena such as diagonal spread and encirclement of wet peat.

WF23127Field-based generic empirical flame length–fireline intensity relationships for wildland surface fires

Carlos G. Rossa 0000-0002-6308-4235, David A. Davim 0000-0001-8682-9917, Ângelo Sil 0000-0003-2074-6558 and Paulo M. Fernandes 0000-0003-0336-4398
 

We developed empirical relationships linking fireline intensity and flame length, based on a compilation of data collected in field head fires, conducted worldwide in forest, shrubland and grassland. Two relationships emerged, respectively for forest and shrublands and for grasslands, and were deemed suitable for scientific and operational application.

WF23129Factors influencing wildfire management decisions after the 2009 US federal policy update

Stephen D. Fillmore 0000-0003-0032-0795, Sarah McCaffrey, Rachel Bean, Alexander M. Evans, Jose Iniguez, Andrea Thode, Alistair M. S. Smith and Matthew P. Thompson
 

This research expands on previous work exploring the decision making of US Forest Service wildfire managers, using social science methods to elucidate the factors that help drive their decisions to suppress or manage wildfires. We found a complex network of factors that show increasing ambiguity in the wildfire decision environment.

WF23124Forest fire progress monitoring using dual-polarisation Synthetic Aperture Radar (SAR) images combined with multi-scale segmentation and unsupervised classification

Age Shama, Rui Zhang 0000-0002-0809-7682, Ting Wang, Anmengyun Liu, Xin Bao, Jichao Lv, Yuchun Zhang and Guoxiang Liu
 

This paper describes a method to monitor forest fire progress using dual-polarisation Synthetic Aperture Radar (SAR) images combined with multi-scale segmentation and unsupervised classification. We aimed to take full advantage of the many different dimensions of feature parameter changes caused by forest fires, relying on time-series dual-polarised SAR imagery to achieve burned area extraction and forest fire progress monitoring.

WF23078Accounting for among-sampler variability improves confidence in fuel moisture content field measurements

Kerryn Little 0000-0002-8303-5297, Laura J. Graham 0000-0002-3611-7281 and Nicholas Kettridge 0000-0003-3995-0305
 

Citizen science provides an important opportunity for the wildfire community, enabling data collection at broad spatio-temporal scales. Direct fuel moisture measurement campaigns can maximise these benefits by accounting for natural differences in measurements between individuals. We quantify the magnitude and variability of differences during an intensive fuel moisture measurement campaign.

WF23044LEF-YOLO: a lightweight method for intelligent detection of four extreme wildfires based on the YOLO framework

Jianwei Li 0000-0002-1486-1421, Huan Tang, Xingdong Li, Hongqiang Dou and Ru Li
 

We tested a lightweight architecture called LEF-YOLO for detecting four extreme wildfires. We found improved detection accuracy through multi-scale fusion and attention mechanism, and constructed four extreme wildfire datasets and compared these with multiple object detection models and lightweight feature extraction networks. This method is beneficial for the development of extreme wildfire field robots.

WF23096Phosphorus chemistry in plant charcoal: interplay between biomass composition and thermal condition

Yudi Wu, Lois M. Pae and Rixiang Huang
 

Diagram showing fire condition changes phosphorus chemistry and speciation from plant biomass to fire residue.

Soil phosphorus (P) availability in natural ecosystems relies on the returning of P in plant biomass. This study shows how fire conditions and plant species and their parts interact in determining the physical and chemical forms and solubility of P that control its post-fire cycling in the environment.

WF23020The role of people, parks and precipitation on the frequency and timing of fires in a sub-Saharan savanna ecosystem

Julius R. Dewald, Jane Southworth and Imelda K. Moise
 

This study analyses fire regimes in Zambia’s South Luangwa National Park and Lupande Game Management Area. It examines the influence of climate and human activities on burned areas. Findings show differences in burned areas and highlight the significance of soil moisture and rainfall in shaping fire regimes in African savannas.

WF23060Associations between Australian climate drivers and extreme weekly fire danger

Rachel Taylor, Andrew G. Marshall, Steven Crimp, Geoffrey J. Cary, Sarah Harris and Samuel Sauvage
 

This paper explores the relationships between the major forces influencing Australian weather and climate, and the chance of severe fire seasons. The findings could be valuable in decision making and preparation for upcoming fire seasons to avoid more seasons with devastating outcomes such as the 2019–2020 Black Summer.
