Abstract

In this study the possibilities of converting Bartın-region oak coppices (Quercus sp.L) into high forests. The

study has been performed in 50 sample plots and in addition to the data obtained from sample plots stem analysis

values of 30 oaks have been inspected. The development of volume and volume components of oak in single tree

has been determined by using stem analysis values of sample trees. The data obtained from sample plots have

been utilized to examine the development of stand volume and volume components with respect to time. By the

help of the amount of product types, product amounts from stand have been calculated according to various

rotation length alternatives. Present Net Values have been calculated by using income and expenditure data.

High forest and coppice investment alternatives have been compared in the aspect of wood production abilities

and discounted net values they provide and their effectiveness have been stated.

Bartın Yöresi Meşe (Quercus sp. L.) Baltalıklarının Koruya Dönüştürülme Olanaklarının Araştırılması

Abstract

Bartın yöresindeki Meşe (Quercus sp.L.) baltalıklarının koruya dönüştürülebilme olanakları araştırılmıştır.

Çalışma 50 örnek alanda gerçekleştirilmiş ve örnek alanlardan toplanan verilere ilave olarak, 30 meşe ağacının

gövde analizi değerleri incelemeye tabi tutulmuştur. Meşenin tek ağaçta hacim ve hacim elemanlarının gelişimi,

alınan örnek ağaçların gövde analizi değerlerinden yararlanılarak saptanmıştır. Meşcere hacim ve hacim

elemanlarının zamana göre gelişimlerini incelemek amacıyla alınan örnek alanlardan elde edilen verilerden

yararlanılmıştır. Ürün çeşitlerinin miktarları yardımı ile meşcereden idare süresi sonuna kadar elde edilebilecek

ürün miktarları çeşitli idare süresi alternatiflerine göre hesaplanmıştır. Gelir ve gider verileri kullanılarak 100 yıl

idare süresi için iki farklı iskonto oranı ile Net Bugünkü Değerler hesaplanmıştır. Koru ve baltalık yatırım

alternatifleri toplam odun üretim gücü ve sağladıkları iskonto edilmiş net gelirler yönünden kıyaslanarak

etkinlikleri ortaya konulmuştur.
