Bark proportion of Scots pine industrial wood

Abstract Bark characteristics are not only used in the forest-wood supply chain, for example to calculate standing volumes, but also transform wood volumes and masses. In this study, bark thickness, volume mass were analyzed on basis of 150 Scots pine discs, with a mean diameter 13 cm. The double thickness was 3.02 mm, proportion 5.6% 3.3%. proportions significantly affected by log-specific variables ‘diameter over bark’, ‘proportion damage’ ‘double thickness’.
