Batı Karadeniz Bölgesi Sahilçamı Ağaçlandırmalarında Teknik ve Ekonomik Değerlendirmeler

Bu makalede Bartın-Karaçaydere serisinde 1979-1984 yılları arasında tesis edilen sahilçamı (Pinus pinaster Aiton.) plantasyonlarının teknik ve ekonomik bir değerlendirmesi yapılmıştır. Bu kapsamda farklı arazi hazırlığı tekniklerinin (makine ve işgücü) uygulandığı plantasyon alanlarından toplam 60 adet deneme alanı alınmıştır. Deneme alanlarında ölçüm ve tespitler 2003 yılında gerçekleştirilmiştir. Yapılan ölçüm ve tespit sonuçlarına göre, sahilçamı plantasyonlarının yanlış mekanizasyon tekniklerinin uygulanmasına, hatalı orijin seçimine ve kar zararına rağmen büyüme ve ürün verimi yönünden memnun edici düzeyde olduğu ortaya çıkmıştır. Buna göre makineli arazi hazırlığı yapılan plantasyon alanında yıllık ortalama artım 12,3 m3 /ha, insan gücü ile arazi hazırlığı yapılan plantasyon alanında ise yıllık ortalama artım 9,8 m3 /ha olarak tespit edilmiştir. Diğer taraftan Net Bugünkü Değer, İç Kârlılık Oranı ve Fayda/Maliyet Oranı kriterlerine göre gerçekleştirilen ekonomik analizler sonucunda, yörede farklı yıllarda tesis edilen sahilçamı plantasyonlarının, araştırma alanının doğal türü olan doğu kayını (Fagus orientalis Lipsky.) ormanlarına göre daha verimli ve kârlı bir yatırım olduğu belirlenmiştir.

Technical and Economical Evaluations of Maritime Pine Plantations in Western Black Sea Region of Turkey

AbstractIn this study, technical and economical evaluations of the maritime pine (Pinus pinaster Aiton.) plantations, established at Bartın-Karaçaydere between the years of 1979 and 1984, were made. 60 sample plots were allocated by representing the establishment techniques of mechanization and labour. The data were collected from the plots concerning growth, yield and economics, in the year of 2003. Reasonable growth rates were obtained in maritime pine plantations, in spite of the negative conditions of inadequate mechanization techniques, wrong origin and snow damages. Mean annual volume increments were calculated as 12.3 m3/ha and 9.8 m3/ha for the sites prepared by mechanization and labour, respectively. The results obtained from the economical evaluations indicated that maritime pine plantations were more productive and profitable than indigenous oriental beech forest in the area as regards the criteria of Net Present Value, Internal Rate of Return and Benefit Cost Ratio.Keywords: Maritime pine (Pinus pinaster Aiton.), oriental beech (Fagus orientalis Lipsky.), industrial plantation, growth and yield, economical analysis.
