Abstract:
The aim of this study is to determine and analyse how the results from forest airborne laser scanning can be utilised when analysing the availability of forest fuel in the regional level. During last years, Finland’s forest inventory has been made by airborne laser scanning method. The analysing method and the potential availability of forest energy have been presented with a case example in this study. In Finland, the most important renewable energy sources are wood fuels which share is about 73% from renewable energy sources. The increased demand of wood fuel needs new methods to define the availability of wood fuels. The forest owners need to be activated to administer their property effectively. The laser scanning results indicate the volume of roundwood (m3) and the forest energy potentials from small-diameter energy woods, stumps and logging residues. The different limitations such as the share of recovery, technical, ecological and economical limitations can be taken into account in the analyse. The results of the analyse by forest plots can be presented on the Internet based applications, such as ARCGIS. There is willingness to use wood fuels more extensively in Finland. The new potential users are especially in the municipalities’ district heating sector and space heating in rural areas where the imported natural gas and fuel oil may be replaced by domestic fuels. In energy production, the use of forest energy must be sustainable. By using airborne laser scanning method, the forest energy resources can be evaluated more effectively and more specifically.
