  Evaluation of Antioxidant Properties of Wild and Cultivated Blueberry Leaves and Their Phenolic Compound

  Okan, Onur Tolga; Ulusoy, Esra; Öz, Mehmet; Deniz, Ilhan

  Aim of study: This study aimed to investigate the antioxidant activity and polyphenol and flavonoid content of blueberry leaves, which could have positive effects on human health. Area of study: The research was conducted in three cities of Turkiye's Karadeniz region, where blueberry cultivation is prevalent: Giresun, Trabzon, and Rize. Material and method: In this study, 29 blueberry leaves (27 cultivated and two wild) were selected as sample materials. The total phenolic content (Folin-Ciocalteu method), total flavonoid content (aluminum (III) chloride method), and total antioxidant capacity (DPPH and FRAP) of the samples were analyzed. Phenolic characterization was performed using HPLC. Main results: The total phenolic content varied between 8.36 and 121.61 mg GAE/g, whereas the total flavonoid content ranged from 0.91 to 3.07 mg QE/g. The results revealed that blueberry leaves had high antioxidant activity and contained considerable amounts of polyphenols and flavonoids. Chlorogenic acid was identified as the dominant compound in all leaves samples. Research highlights: These findings indicate that blueberry leaves could be a valuable source of antioxidants in the food and cosmetic industries, comparable to the fruit itself.

  Determination of the Effects of Alucra Forest Planning Unit's Population Dynamics on Land Use Changes

  Çakir, Gunay; Kaya, Latif Gurkan; Yücedag, Cengiz; Bayram, Sitki

  Aim of study: This study is done to monitor temporal land use/land cover changes in a typical mountain watershed covering an area of 135441.0 ha in North Eastern of Turkey based on rural demographic dynamics and forest management plans belonging to the years 1987 and 2013 coupled by GIS analyses. It also investigates changes in the shape of land use class (LUC) over the period. Material and Methods: The changes occurring time wise and positional on the base of the local LUC was examined by benefiting from the forest management plans from 1987 to 2013. Moreover, the change of LUC around these areas has been examined with the 1000 m zones thrown around the settlement areas and correlated with the fast decrease of the population recent years. Demographic dynamics (increase or decrease) affect the usage of forest lands, as well. Main results: While there was an increase in the productive forest lands (pure coniferous and deciduous, and mixed forest) between 1987 and 2013. In the same periods there was a decrease in agricultural and sandy areas. The increase of patches in the productive forest lands mostly resulted from afforestation works conducted in the unproductive forest lands, and forestry maintenance activities. Another reason for this increase of forest patches is why people have immigrated to urban areas in the last years. Research Highlights: It can be said that one of the most important causes in the rise of the forest resources in the Alucra Forest Planning Units (FPU) is the time wise changes of social structure. Furthermore, the forestry activities in the study between 1987 and 2013 are also the other significant factor in this increase of forest resources.

  Kadıoğulları, Ali İhsan; Bingöl, Özkan; Keleş, Sedat; Baskent, Emin Zeki

  Bu makalede, ekosistem tabanlı çok amaçlı planlama anlayışına göre geliştirilmiş bir simülasyon tabanlı konumsal orman amenajmanı planlama modeli tanıtılmıştır. Öncelikle modelin genel mimari çatısı kısaca açıklanmıştır. Model daha sonra örnek bir orman planlama biriminde uygulanmıştır. Bu amaçla konumsal özellikleri dikkate almayan bir temel simülasyon senaryosu ile farklı konumsal özelliklerin yer aldığı üç farklı planlama senaryosu olmak üzere toplamda dört tane planlama senaryosu üretilmiştir. Bu planlama senaryoları değişik performans göstergeleri (eta, dikili servet, net karbon birikimi, simülasyon süresi sonundaki yaş sınıfı dağılımı) kapsamında karşılaştırılmıştır. Planlama senaryolarının karşılaştırılması sonucunda, konumsal olmayan planlama senaryosu ile konumsal planlama senaryoları arasında eta açısından büyük farklılıkların olmadığı saptanmıştır. Ancak, konumsal planlama senaryoları ile birlikte orman ekosisteminde konumsal düzenlemenin etkin bir şekilde yapıldığı ve daha uygulanabilir orman amenajman planlarının üretilebileceği belirlenmiştir

  Preparing Forest Management Plans With Spatial Simulation Model

  Kadiogullari, Ali Ihsan; Keles, Sedat; Baskent, Emin Zeki; Bingöl, Ozkan

  This manuscript presents a simulation-based spatial forest management planning model developed for ecosystem-based multiple use forest planning approach. The general framework of the simulation model was firstly introduced. It was then implemented in a typical forest management planning unit. Four forest management planning scenarios including nonspatial and spatial characteristics were developed. These scenarios were compared in the context of different forest performance indicators (such as allowable cut, growing stock, net carbon sequestration, age-class distribution at the end of the simulation). When compared the simulation-based forest management planning scenarios, it was found that there were no significant changes in timber production levels among scenarios. On the other hand, spatial forest management scenarios controlled forest ecosystem structure and produced more applicable forest management plans.

  Structural Analysis of Forest Product Businesses in GümüşhaneProvince

  Yaşar, Mehmet; Adanur, Hakan; Top, Yener; Oz, Mehmet

  In total, 95% of all business enterprises established in Turkey are micro-scale, and this figureincreases to 98.6% in the forest products industry. Micro-scale enterprises are important in terms ofproduction, employment, and overcoming economic imbalances among regions. The forest productsindustry, which includes three subdivisions within the manufacturing sector, occupies an important placein the overall Turkish manufacturing sector. Thus, this study examined the structural characteristics offorest product enterprises in Gümüşhane Province. The research involved in-person interviews withpersonnel at 47 enterprises. The data revealed that the sawmill division was especially important withrespect to the use of local poplar logs. The sawmill and furniture divisions accounted for 28% of allenterprises and 26% of all employees in the manufacturing sector in Gümüşhane. We found that 57% ofenterprises had difficulty in finding working capital and 55% of enterprises experienced shortages oflabour. The average contribution of each forest products business to employment (2.55) was more thanthat of other manufacturers in Gümüşhane (2.27). The forest product businesses in Gümüşhane resembleother micro-scale enterprises located in other regions of Turkey in terms of their structural properties.
