Özet:

 This study was carried out to evaluate the influence of thinning on natural Brutian pine Pinus brutia Ten. stands in IspartaSütçüler Forestry Management Directorate. The effect of the four-year results of thinning on the growth characteristics of Brutian pine stands was evaluated at two different levels applied in two different areas at similar elevation. Moderate thinning was performed in area I, and heavy thinning was performed in area II. Thinning applied in Brutian pine stands in both areas had an effect on mean diameter at breast height, tree height, tree stability and total basal area. Tree stability, diameter and height growth of trees increased with the thinnings applied. At the end of four years, no significant difference was determined between the areas where thinnings was applied and the control areas in terms of the total volume per hectare in both areas. As a result, heavy thinning may be preferred as the first thinning in areas where regular maintenance is applied in natural Brutian pine stands. In areas where regular maintenance is not applied, moderate thinning can be applied considering the development of the stand.

 Bu çalışma IspartaSütçüler Orman İşletme Müdürlüğü sınırları içerisinde bulunan doğal kızılçam Pinus brutia Ten. meşcerelerinde uygulanan aralama müdahalelerinin değerlendirilmesi amacıyla yapılmıştır. Kızılçam meşcerelerinde benzer yükselti ve bakıda iki ayrı sahada uygulanan iki farklı şiddetteki aralama müdahalesinin dört yıllık sonuçlarının büyüme özellikleri üzerindeki etkisi değerlendirilmiştir. I nolu alanda mutedil alçak aralama müdahalesi uygulanırken, II nolu alanda kuvvetli alçak aralama müdahalesi gerçekleştirilmiştir. Kızılçam meşcerelerinde her iki alanda da uygulanan aralama müdahaleleri ortalama göğüs çapı, ağaç boyu, ağaç stabilitesi ve hektardaki toplam göğüs yüzeyi üzerinde etkili olmuştur. Aralama müdahaleleri ile ağaçların göğüs çap ve boy gelişimi, ağaç stabilitesi artmıştır. Dört yılın sonunda her iki alanda da hektardaki toplam hacim bakımından aralama müdahalesi uygulanan alanlar ile kontrol alanları arasında istatistiksel anlamda önemli bir farklılık belirlenmemiştir. Sonuç olarak, düzenli bakım müdahalesi uygulanan doğal kızılçam meşcerelerinde ilk aralama müdahalesi olarak kuvvetli alçak aralama tercih edilebilir. Düzenli bakım müdahalesi uygulanmayan alanlarda ise meşcere gelişimi de göz önüne alınarak mutedil alçak aralama müdahalesinin uygulanması önerilebilir.
