Abstract:
An increasing demand for forest biomass to energy is leading to a more intensive harvesting of timber, also including an exploitation of the crown biomass. This sets new demands for forest inventory systems to generate more detailed information about the forest biomass fractions. Norway has unutilized forest resources, which can be used for bioenergy. These also include Norway spruce (Picea abies (L.) Karst.). The material was sampled from three different locations in Southern Norway from west to east. Each location was represented with tree different site indices. Vertical profiles of branch weight, length and diameter were studied. The effect of different tree and site characteristics were used to predict the profiles. Significant differences were found between the geographical locations studied after adjusting for tree height and diameter in breast height. Branches from the western site were longer and had a greater mass compared to branches from the other two locations. The branch diameter distribution indicated that the east location had larger branch size, while branches in middle and west site had smaller sizes. This study highlights the range of branch variability within locations, but indicates that Norway spruce branch biomass in Norway may be considered as a valuable raw material.
