Polska - Opis:
- Mountain regions are the main natural ranges of spruce forests in Poland. Their occurrence and growth in these areas is associated with the height above sea level and exposure. The attempt of the study was to determine the impact of these two characteristics on the quality of spruce timber. The research was carried out on 20 sample plots located in the Sudety (8 plots) and the Carpathians (12 plots). The trees growing on the selected plots were examined for their diameter at breast height and height, the quality of standing timber and the kinds and varieties of wood defects on tree stems. As a result of the conducted analyses it could generally be stated that forest stands from the lower montane zone produced higher quality timber in terms of both volume and quality and that the best quality stands were on the western and the poorest ones – on the southern slopes.
