WF17019Indicators of burn severity at extended temporal scales: a decade of ecosystem response in mixed-conifer forests of western Montana

This study monitored wildfire effects for a decade following forest fires, and highlights the use of fractional cover mapping over multiple spatial scales. Char cover was the primary field and remotely sensed indicator of high burn severity for the first full year after the fire. The ecological response trajectory varied depending on the degree of initial disturbance; however, all sites had significant understorey vegetation cover after a decade.

WF16141Assessment of burn severity in Middle Povozhje with Landsat multitemporal data

pp. 772-782

This paper studies burnt forest areas for 2010 wildfires in the Republics of Mari El and Chuvashia of the Russian Federation with the use of Landsat time series images. The use of differenced Normalized Burn Ratio (dNBR) and Composite Burn Index (CBI) provided a valuable approach for estimating burnt severity levels.

Fire can affect the relative amounts of carbon and nutrients in the soil–plant system. In Australian eucalypt forest sites, we found that recent fire was associated with a shift in the balance of soil carbon, nitrogen and phosphorus that favoured phosphorus. This suggests that fire enhances the cycling of nutrients, and particularly of P, in low-phosphorus ecosystems.

WF17021Forest fire risk assessment using point process modelling of fire occurrence and Monte Carlo fire simulation

pp. 789-805

We developed a landscape-level fire risk assessment approach that integrates fire occurrence probability, fire spread and government-appraised land values. A spatial point processing method was used to generate a spatial distribution of probability density of fire occurrence, and Monte Carlo fire spread simulation was carried out to compute burn probability across a landscape.

WF16217Using alternative soil moisture estimates in the McArthur Forest Fire Danger Index

pp. 806-819

The McArthur Forest Fire Danger Index is currently used in Australia to assess bushfire hazard. The index relies on the Keetch–Byram Drought Index to estimate soil dryness, yet improved approaches for estimating soil moisture have become available. This article evaluates the effect of employing alternative soil moisture estimates on the bushfire hazard index.

This study examines wildfire risk awareness and wildfire prevention in a predominantly Indigenous Māori community in New Zealand’s Far North where fire use is prevalent. Participants were aware of the high wildfire risk, and although some efforts were made to use fire safely, instances of unsafe fire use were identified. Factors that influenced awareness and wildfire prevention are discussed.

WF16045Effect of two-way coupling on the calculation of forest fire spread: model development

A. M. G. Lopes, L. M. Ribeiro, D. X. Viegas and J. R. Raposo
pp. 829-843

The standard procedure when simulating fire spread is to take the unperturbed wind flow as input data. In this work, we propose a new formulation that considers thermal effects from the fire front on the wind field. The first part of this work describes the underlying models and preliminary tests.

WF17038Comparison of three methods to quantify the fire spread rate in laboratory experiments

J. S. Gould, A. L. Sullivan, R. Hurley and V. Koul

Measurements of rate of spread of fires burning eucalypt litter fuel in a combustion wind tunnel by ocular observation, visible spectrum video imagery and thermocouple instrumentation of fires are compared. Overall, the three methods gave similar results, but some of the mean values were significantly different depending on the dryness of the fuel and speed of the wind.

WF16183Modelling the drivers of natural fire activity: the bias created by cropland fires

İsmail Bekar and Çağatay Tavşanoğlu

We modelled the drivers of fire activity from MODIS fire data using different datasets created by the exclusion of vegetation and cropland land cover classes. Cropland fires had a significant effect on model output. A clear distinction should be drawn between wildland and cropland fires in such models.
