The effect of elevation and exposure on stability index and quantity of snags in pure Oriental beech (Fagus orientalis Lipsky.) managed forests

Öz

Snags are a major structural and functional component in oriental beech (Fagus orientalis Lipsky.) because of their high degree of naturalness in northern Anatolia forests. This research, as a case study, was conducted in the even-aged and pure oriental beech managed forest in Bartın. In this research where the effect of exposure and elevation, zone factors on stability index, the number and volume of snags (standing coarse deadwood: CDWsnags) were examined. It was found that exposure did not affect the stability index, number and volume of CDWsnags. However, there is a significant difference among the elevation zone on the number of CDWsnags, their volume and stability index (P≤0,000). It was found that there is an average volume of 8.87 m3/ha of CDWsnags. The diameter of the snags is distributed between 32 and 72 cm. In addition, a strong positive correlation was determined between the number of CDWsnags and the stability index (r= 0,95), height and breast diameter of CDWsnags (r = 0,98). These results may be an important tool to be used to improve management interventions in the management of high value forests.

Saf Doğu Kayını (Fagus orientalis Lipsky.) işletme ormanlarında yükselti ve bakının dikili ölü ağaç sayısı ve stabilite indeksine etkisi

Öz

Ölü ağaçlar, yüksek doğallık dereceleri nedeniyle kuzey Anadolu doğu kayını doğu ormanlarının önemli bir yapısal ve fonksiyonel bileşendir. Örnek olay olark bu araştırma, Bartın’da aynı yaşlı ve saf doğu kayını işletme ormanında yürütülmüştür. Bu araştırmada, bakı ve yükselti faktörlerinin birey stabilite indeksi, dikili ölü ağaç (CDWsnags) sayısı ve hacmi üzerine etkisi incelenmiştir. Dikili ölü ağaç (CDWsnags) hacmi, sayısı ve stabilitesi üzerine bakı faktörünün etkisi tespit edilmemiştir. Ancak, yükselti zonları arasında dikili ölü ağaç (CDWsnags) sayısı, hacmi ve stabilitesi üzerinde önemli farklılık bulunmuştur (P≤0,000). Hektardaki dikili ölü ağaç hacmi ortalaması 8.87 m3 olarak bulunmuştur. Dikili ölü ağaçların çapları 32 ile 72 cm arasında dağılım göstermiştir. Ayrıca, dikili ölü ağaçların (CDWsnags) sayısı ile stabilite indeksi (r= 0,95) ve boy ile göğüs çapı (r = 0,98) arasında güçlü pozitif korelasyon belirlenmiştir. Bu sonuçlar, yüksek değerli ormanların yönetiminde yönetim müdahalelerini iyileştirmek için kullanılacak önemli bir araç olabilir.
