This research aimed to investigate the competitive situation and the growth reduction as a result of competition for brutia pine trees grown in Kafardabeel stand – Jableh. In the year 2015, 15 circle plots (with area size of 400 m²) in the study area planted in 1974 were sampled; all variations in the site like tree density, aspect, slop, topography and site fertility were covered. In the sample plot diameter at breast height of all trees and also coordinates of central tree and coordinates of all compotators as well as were measured. In order to study the competitive situation, two different types of competition indices: position dependent (Heygi1, Heygi2, BAL) and position independent (CCF) indices were used.
