Abstract:

In Türkiye, oaks with a broad distribution necessitate species-specific information regarding growth, increment, and yield for the sustainable management and conservation of forests. These data contribute not only to determining the yield of firewood and timber, but also to obtaining valuable byproducts such as fruits, leaves, bark rich in volatile compounds, and fruit shells, which serve as animal feed. This study underscores the necessity of examining the 17 oak species in Turkey at the species level. In this research conducted within the Bursa Regional Directorate of Forestry (RDF), the relationships individual tree characteristics and stand parameters were addressed within the stands of Turkey Oak (Quercus cerris L.). When examining the relationships at the individual tree level, it has been observed that the diameter at the breast height (DBH) – stump diameter (dbh – dst) has the highest coefficient of determination (R2: 0.972), while the bark thickness – DBH (2b – dbh), tree height - DBH (h- dbh), and tree age - DBH (T -dbh) follow. In stand-based relationships, it was noted that the relationship between stand age and stand trees (T-N) has the highest coefficient of determination (R2: 0.776), followed by stand trees – quadratic mean diameter (N - dq), stand age - height of mean basal area tree (T- hg), and top height– stand age (h100-T), respectively.
