Stand Structure Dynamic of Turkish Pine (Pinus Brutia) Grown Naturally in the Atrush Region, Iraq

Abstract

Coniferous woods of uneven age have a natural distribution in Atrush, Iraq, and this study selected 10 random samples from diverse places and densities to understand their stand dynamics, using a 17.9 m radius circular sample. The tree and stand variables and global tree coordinates measurements occurred for each sample. Using different diameters to measure total height determined the phases of tree seedlings. When the diameter was over 10 cm, the trees were over 1.3 m tall. Through analysis, it revealed that the densities of these trees spread in the study site and reached 28181.89 trees that varied widely. The number of tree members at the lower diameter was the highest, fluctuating from sample to sample, indicating variances in natural renewal between study sites. The site is rich in natural regeneration. Samples 2, 8, and 10 showed balance for the quantity of seedlings, juveniles, and trees, indicating stability in tree movement. The obtained results relied on mechanisms of community aggregation using tree spatial distribution data.
