Smoulder is a type of slow, low-temperature combustion of relevance to bushfires. It occurs both in pre-fire and post-fire stages. Many fires are caused by smouldering fire; once ignited, smouldering often lasts for days or weeks and can turn into flaming combustion.
Optimisation of prescribed burning requires a strong understanding of the underlying variability of fuel, vegetation and soil.
This project focuses on improving the capability of land managers to use prescribed fire to reduce fuel loads, while at the same time mitigating the risks of loss of water yield and carbon sequestration capacity.
Fuel on the ground, such as leaves, twigs and decomposing matter, accumulate over time and account for a large percentage of the total fuel load in forests. The air permeability of the litter layer is a critical factor that influences fire behaviour because the aire permeavility controls the amount of oxygen available for the combustion in the fuel bed.
Soil organic matter has strong effects on soil properties such as water holding capacity, soil structure and stability, nutrient availability and cation exchange capacity. Bushfire can change these properties depending on intensity and duration of heating. Pyrolysis coupled to gas chromatography-mass spectrometry (pyr-GC-MS) is a novel technique that can been used for soil characterisation.
