The vegetation type is the critical factor in evaluating how a wildfire will behave on-site at the burning time. Plant flammability is tested in a wide range of experiments in a laboratory in Creswick campus to visualize the ability of plants' ignitability and combustibility, as well as the ability to sustain combustion. In this case, based on an exploration of plant flammability and structure of forest stratum, forest flammability model is used to assess the influence of historical flammability in Buangor Forest following the 2010 fire. This research aims to find how fire severity effects predicted flammability using the Forest Flammability Model. The investigators analyse the data collected in different severity types in Buangor Forest from site study and compare their main features. Across three severity types, in Eucalyptus-dominated damp and dry forest, we measured Fuel Hazard Scores and Fuel Weights on-site, dimensions of different species (base height, top height, width). We estimated the spacing and density of them. The study in the essay mainly demonstrates flame height and flame length as referred data to analyse the effect of flammability. However, specific leaf area or bulk density may promote cumulative effects in some instances, or they could create counteractive effects because of high moisture content. Comparing with plant traits in different fire severity in both mild and severe weather condition will be necessary to identify important contributions to forest flammability from the composition of species.
