Mass and density of birch pulpwood harvested from stands in different types of forest habitats
Journal Title: Forestry Letters - Year 2015, Vol 108, Issue
Abstract
Density is one of the most important properties, on the basis of which other characteristics and attributes of lumber are evaluated. One of its more practical applications is in the evaluation of the load mass of pulpwood. Taking into consideration the high variability of lumber density and how this attribute is influenced by the habitat, a pilot experiment was carried out which involved comparing the mass (kg) and the green density (kg/m3) of lumber harvested from stands in habitats differing in terms of soil fertility. The forest habitat type is a factor which significantly affects the wood volume, and thus also the mass of the freshly harvested birch pulpwood. In a more fertile habitat the average volume and true mass of the lumber were higher. However, growth and development conditions defined based on the type of habitat did not have an effect on the average density of the birch pulpwood. At low volumes,the mass and density of logs in both analysed habitats are similar. The differences are more marked when the wood volume is greater.
