Characteristic values determined from wood samples with a moisture content of 12%.
Its large distribution and high productivity in the right location makes the Spruce Tree (Picea abies) one of the most important kinds of trees, commercially, for Europe.
Its wood is moderately heavy, resilient and almost-white with a strong natural lustre.
Spruce trees are the source of valuable raw material for the paper and plasterboard industries, and are also used as construction timber to make furniture.
