The Relationships between Diameter at Breast Height, Tree Height and Crown Diameter in Calabrian Pines (Pinus brutia Ten.) of Baskonus Mountain, Kahramanmaras, Turkey

In this study, the relationships between height-diameter at breast height (DBH), crown diameter-DBH and crown diameter-height were investigated in Calabrian pines (Pinus brutia Ten.) of Baskonus Mountain, Kahramanmaras. Four sample plots were selected from pure Calabrian pine stands and DBH, height and crown diameter were measured on the live Calabrian pine trees, of which DBH was > 4 cm, in these sample plots. At the end of the regression analysis carried out on the data of a total of 134 trees, it was determined that there were statistically significant (P<0.0001) and strong (R2>0.50) relationships between DBH, height and crown diameter variables in Calabrian pines. The strongest relationship determined was the height-DBH relationship (R2=0.82), followed by the crown diameter-DBH (R2=0.74) and crown diameter-height (R2=0.62) relationships, respectively. The results of the study indicated that the height-DBH relationship can be described by the second-degree polynomial model, while the crown diameter-DBH and crown diameter-height relationships can be described by the power model and heights and crown diameters can be estimated by means of DBH, of which measurement is easy, in Calabrian pines of the research area.
