This experimental study investigates the behaviour of merging fire fronts during controlled burns in Australia. Results showed that forward junction fires spread significantly faster than linear fires and can lead to more dynamic fire behaviours, highlighting the need for further research to improve fire behaviour models and safety measures.

Current fire behaviour modelling assumes that ROS depends on the three factors of the classical fire environment triangle, without considering the convective processes, resulting the interaction between fire and environment. Sets of model parameters to predict the temporal variation of the ROS in the acceleration and deceleration phases were proposed.

Using 1621 treatment sequences applied to areas subsequently intersected by wildfires in California, we show 61% of the treatments were effective. Fire and fuel removal treatments were most effective and rearrangement was least effective. Treatment effectiveness enhances when applied at large scale. Weather impacts on treatment effectiveness were minimal.

We demonstrate a new method for combining terrestrial and airborne laser scanning data to estimate fuel consumed by fire and compare how lasers and long-wave infrared imagery estimate consumption. We find that these remote sensing techniques provide comparable consumption estimates and that most fuel consumption occurs on the forest floor.

We dated fire events and measured forest structure in the highly biodiverse Talassemtane National Park in Morocco. Surface fires tended to recur at <25-year intervals in Pinus–Abies–Quercus forests. Fire regime was associated with old trees and open forest structure.

Fuel is a key driver of wildfire patterns but the impacts of changing climate on fuel hazard and availability to burn is often poorly understood. This study uses six future climate models to predict the shifts in landscape fuel patterns across an environmental gradient.

Uncontrolled fire and high elephant densities may cause loss of biodiversity in African savannas. We assessed the status of fire regimes in Botswana’s tourism region, which has an elephant population, to determine whether incentivised fire management could enhance broader ecological management and employment outcomes, while supporting climate change initiatives.

This work presents a simplified model of the firebrand transport equations that allows for faster numerical calculations when using coupled fire atmosphere models. We compared this model with more complex ones using different topographies. The firebrand ground landing densities for both results are compared.

Novel techniques were developed to quickly measure canopy fuel and surface fuel across a range of environmental conditions using a ground-based remote sensing technology. These techniques provide precise, repeatable fuel estimates while minimizing model training requirements.

Destructive postfire debris flows triggered by short-duration bursts of high-intensity rainfall and excessive runoff within 3 years following fire continue to impact California. Using a simplified wildfire scenario, we predicted potential postfire debris-flow hazards statewide. We suggest the maps are useful for identifying areas that pose the greatest postfire geohazards.

This study explores the association between human activities and wildfire occurrences in the Tsavo Conservation Area. Statistical methods (ANOVA, chi-square and Kendall’s tests), were applied for data analysis. Chyulu Hill National Park experienced the highest frequency of wildfires, and eleven human activities were pinpointed as contributing factors.

Prescribed burning in eucalypt woodlands exposes skinks to lethal temperatures, which are partially remediated by rock and log shelters. Ambient and maximum temperatures were positively associated, and high ambient temperatures increased duration of lethal temperatures. Assessing shelter availability for small vertebrates before prescribed burning should be a conservation priority.
