AB  - Aim of study: In this study, the effects of bark streak tapping resin extraction on tree mortality risk and survival rates across diameter classes in Pinus brutia forests are looked into.Area of study: Research was conducted in the Korudağ Forest Sub-District, Keşan Forestry Department, and Çanakkale Forest Regional Directorate in Türkiye.Material and method: We monitored 396 trees for 17 months, extracting resin every 15 days. We used Kaplan-Meier survival analysis to assess the mortality risks for three diameter classes: pole stage (8-19.9 cm), small wood (20-35.9 cm), and mature (36-51.9 cm.)Main results: Smaller-diameter trees (8-19.9 cm) exhibited the highest mortality risk with a survival rate of 71.1%, while medium-diameter trees (20-35.9 cm) had a survival rate of 93.2%, and larger-diameter trees (36-51.9 cm) showed complete survival. Overall, 41 trees (89.6%) died, with significant differences in survival probabilities among diameter classes.Research highlights: Smaller-diameter trees are more vulnerable to mortality during resin tapping, underscoring the need for sustainable management strategies.

N2  - Çalışmanın amacı: Bu çalışmada, kızılçam (Pinus brutia) ormanlarında açık yara yöntemiyle yapılan reçine üretiminin ağaçların kuruma riski ve farklı çap sınıflarındaki yaşama oranları üzerindeki etkileri incelenmiştir.Çalışma alanı: Araştırma, Türkiye’nin Çanakkale Orman Bölge Müdürlüğü, Keşan Orman İşletme Müdürlüğü’ne bağlı Korudağ Orman İşletme Şefliği sınırlarında gerçekleştirilmiştir.Materyal ve yöntem: 396 ağaç, 15 günde bir reçine üretilerek 17 ay boyunca izlenmiştir. Kuruma risklerini değerlendirmek için Kaplan-Meier yaşama analizi kullanılmış ve ağaçlar üç çap sınıfına ayrılmıştır: sırıklık ve direklik (8-19.9 cm), ince ağaçlık (20-35.9 cm) ve orta ağaçlık (36-51.9 cm)  Temel sonuçlar: Küçük çaplı ağaçlar (8-19.9 cm) %71.1 yaşama oranı ile en yüksek kuruma riskini göstermiştir. Orta çaplı ağaçlarda (20-35.9 cm) yaşama oranı %93.2 iken, büyük çaplı ağaçlar (36-51.9 cm) tamamen hayatta kalmıştır. Genel olarak, çap sınıfları arasında önemli farklılıklarla birlikte toplamda 41 ağaç (%89.6) kurumuştur.Araştırma vurguları: Küçük çaplı ağaçlar, açık yara yöntemiyle yapılan reçine üretimi sırasında kuruma riskine daha duyarlıdır ve bu durum sürdürülebilir yönetim stratejilerinin gerekliliğini ortaya koymaktadır.
