Method for Stand Flammability Classification
The fire risk classification now applied in Poland to forest area allows determining fire risk category for the area of Forest District. However, it is impossible to identify the fire risk on the micro scale. The stand flammability classification according to forest habitat types was based on an analysis of fire outbreaks in the period from 2007 to 2017. In elaborating it consideration was given to the number of fires and the burnt area relative to the area occupied by particular forest habitat types and soil cover types. The classification of stands in terms of fire risk shall enable assessing it at the sub-compartment level and to create an Forest Numeric Map layer. In elaborating the final classification method, the weights of individual indices were dependent on the correlation strength of the density of fires or the burnt area and the presence of selected stand types. Taking the above into account, the formula for the cumulative flammability index was derived. The classification of stand flammability according to forest habitat types shall enable the mapping of forests in terms of their fire characteristics at the sub-compartment level. Since a sub-compartment was a basic mapping unit, this led to very detailed, but too fuzzy mapping, which could limit its practical usefulness in certain situations. Therefore, data generalization rules were developed to enable the determination of the flammability class for larger areas, a compartment and a forest range.
