Variation of bark thickness on single stem of crimean pine (Pinus nigra Arnold. subsp. pallasiana (Lamb.) Holmboe) In Natural Stands: A case study of Isparta region

Abstract

This study was carried out to determine the variation of bark thickness in a single tree in Natural Crimean Pine (Pinus nigra Arnold. subsp. pallasiana (Lamb.) Holmboe). Anatolian Black Pine is a thick-barked species. For this reason, it is important to reveal the values given for the volume, volume increase, and allowable cut of the species in a more reliable way. On the other hand, when it comes to technological developments to benefit from the bark in different ways in the future, determining the inventory values is another feature that makes the aforementioned species important. All these reasons bring Anatolian Black Pine to the forefront in terms of crustal thickness studies. In this direction, within the scope of the study, the relationships between breast height diameter and bark allowance, section height, and bark thickness parameters in different height groups for young and old trees were evaluated by the regression analysis method. The results obtained revealed that there were statistical differences between the diameter of the breast height diameter and the bark allowance, and between the section height and the bark thickness in terms of tree age and height groups.
