| Summary: A total of 65 sample plots were selected from pure and mixed stand to determine the stand structures. Crown projection in the samples plots, and stand profiles were drawn. Growth relations of scotch pine, crimean pine, calabrian pine and beech were investigated in order to determine age-heigh superiority to be given a tree species growing slowly in the process of natural regeneration of mixed stand s. Natural regeneration and its ecological condition were determined with detailed observations and examinations in the sample plots. In the research area, structures of pure calabrian pine, pure oak, pure Crimean pine, pure scotch pine, pure beech stands, calabrian pine+crimean pine, crimean pine+ oak, crimean pine+beech, scotch pine+crimean pine+beech and scotch pine+Crimean pine mixed stands in the research area were determined. These stands have generally different age, two or many storied and loose or light closure structure. However, even aged and one storied structures have also been observed. In the calabrian pine+crimean pine mixed stands, calabrian pine generally grows faster than crimean pine in the respect to age-heigh growth. İn the crimean pine+oak mixed stands, crimean pine generally grows faster than oak. İn the scotch pine+crimean pine mixed stands, scotch pine generally grows faster than crimean pine. İn the crimean pine+oak mixed stands, crimean pine generally grows faster than oak. İn the Crimean pine+beech mixed stands, crimean pine generally grows faster than beech. İn the scotch pine+Crimean pine+beech mixed stands, scotch pine generally grows faster than the other species. The stand structures in the research area have been found very fat to the goal structures. Generally, insufficient thinning have mostly found effective.
