Aim of the study: In the process of global climate change (GCC), the migration mechanism needed especially for forest trees must be provided by humans. For this purpose, contrary to the previous studies, detailed studies to be carried out on small areas are needed. Area of study: In the present study carried out in Kastamonu Regional Directorate of Forestry, which performs the highest level of wood production in Türkiye, it was aimed to specify the actual distribution areas of the Abies and the change in their suitable distribution areas due to GCC. Material and methods: In this study, besides the existing distribution areas and the potential future distribution areas, also the suitable distribution areas were determined by using SSP 126, SSP 370, and SSP 585 scenarios for the years 2040, 2070, and 2100 for Abies at Kastamonu. Main results: The results achieved there showed that, depending on the results of climate change, distribution areas of Abies populations would change in the future and this change would be in form of an increase in general. Research highlights: This species (Abies) seems incapable of keeping up with such changes without human intervention. Thus, considering the study results, it is recommended to make necessary amendments to the forest management plans.

Aim of the study: This study examines the overall color change values from applying water-based, polyurethane, and acrylic varnishes on newly prepared and naturally aged wood materials. Materials and methods: The Turkish woodworking industry commonly selects oak (Quercus petrea L.), chestnut (Castanea sativa M.), and scotch pine (Pinus sylvestris L.) as the preferred wood type for preparing test samples. A total of 360 test samples are prepared for the experiments. The color difference (ΔE*) between two colors is measured using a Minolta CR-231 color measurement device, following the principles outlined in ASTM-D 2244. Main results: On the C.I.E. Lab* color plane, a higher ΔE* indicates a more significant difference between the compared colors. Among the wood type, oak exhibited the highest color change (ΔE*), while chestnut displayed the lowest. Fresh wood materials showed higher color change values (ΔE*) than naturally aged wood materials. The radial section direction also is showed higher color change values (ΔE*) than the tangential section direction. Research highlights: Regarding varnish type, acrylic varnish indicated a minor color change, followed by polyurethane and water-based varnishes, respectively. Acrylic varnish is recommended for studies with minimal color change and for preserving the wood material's natural color.

Aim of studty: The aim of this study is to determine the flood risk map of the study area where floods and flood events are frequently encountered by AHP method. Study area: The study was carried out within the boundaries of the Sinop Regional Directorate of Forestry, Ayancık Forest Management Directorate. Material and method: The flood risk map of the study area was produced by Analytical Hierarchy Process (AHP) method. For AHP, 6 different criteria were used: slope, precipitations, aspect, stream distance, land use, and soil. Forest type maps of the study area were used to analyze the impact of forests on flood risk. In terms of forest structure, the stand structure was divided into 3 classes as coniferous, broadleaf, and mixed forest. Main results: The results showed that flood risk varies with forest structure. Coniferous forest class was determined as the class with the lowest flood risk and mixed forest as the class with the highest flood risk. Research highlights: It was determined that the flood risk changed according to the forest structure. Coniferous forest class was determined as the class with the least flood risk, and mixed forest was determined as the class with the highest flood risk.

Aim of study: Pine wilt disease (PWD) is a serious threat to the susceptible pine forests. It is caused by Bursaphelenchus xylophilus (Nematoda: Parasitaphelenchidae) (Steiner and Buhrer 1934), Nickle 1970 and transmitted by Monochamus Dejean beetles. In the recent study, we assessed the effects of entomopathogenic nematode, Steinernema carpocapsae (Nematoda: Steinernematidae) against Monochamus galloprovincialis larvae in Anatolian black pine and Scots pine logs.
Area of the study: The experiments were conducted in Duzce University, Faculty of Forestry and in a pine forest at Duzce University campus area.
Material and methods: The mean number of eggs per pine logs, and the productivity of S. carpocapsae in M. galloprovincialis larvae were compared under laboratory conditions. The nematode experiments were conducted using oviposited pine logs in the field.
Main results: The females of M. galloprovincialis oviposited more eggs on Scots pine compared to black pine logs. Both in black pine and in Scots pine, the survival rates of M. galloprovincialis after nematode application was significantly lower than control.
Highlihts: As a result of the study, S. carpocapsae can be an efficient biological control agent of this wood-boring insect.

Aim of study: It is an investigation of the effects of bleaching processes on the color change in the wood of tree species. Tree species Eastern Beech (Fagus Orientalis Lipsky.) and Eastern Black Sea Fir (Abies Nordmanniana subsp.) were used in the study. Sodium hydroxide-hydrogen peroxide, oxalic acid, peracetic acid diluted 1/3, peracetic acid diluted 1/6 were used as bleaching agents. Trial samples were prepared in accordance with standards and color change measurements were made.
Area of study: Surface treatments on wooden materials
Material and methods: In the study, two wood species and one varnish type were used; Color changes were tested by applying various bleaches to the wooden material by rubbing method.
Main results: As a result of the study, differences were observed in all cross-section shapes in beech wood bleaching measurements with 1/6 diluted peracetic acid, and differences were observed in cross-section shapes in fir wood bleaching measurements. The best bleaching of fir wood was achieved with peracetic acid.
Main results: As a result of the study, differences were observed in all cross-section shapes in the beech wood bleaching measurements with 1/6 diluted peracetic acid, and in the cross-section shapes in the fir tree bleaching measurements. The best bleaching of fir wood was achieved with peracetic acid.
Highlights: The bleaching process allows the wooden material to easily acquire a homogeneous color. Since the cell arrangements are different in different cross-sectional shapes, the bleaching rates are different from each other. While there is not much difference in the color changes in the wood material when bleached with oxalic acid, the samples are bleached as a result of bleaching with sodium hydroxide-hydrogen peroxide and peracetic acid. Significant changes have occurred in color changes. The reason for this difference is due to the different degrees of corrosion of bleaching agents.
研究目的:研究漂白过程对树种木材颜色变化的影响。研究对象为东部山毛榉(Fagus Orientalis Lipsky.)和东部黑海冷杉(Abies Nordmanniana subsp.)。以氢氧化钠-过氧化氢、草酸、过氧乙酸稀释1/3、过氧乙酸稀释1/6作为漂白剂。按照标准制备试品，并测量颜色变化。
研究领域:木质材料的表面处理
材料和方法:研究中使用了两种木材和一种清漆;用摩擦法对木材进行各种漂白剂处理，测试其颜色变化。
主要结果:研究结果表明，1/6稀释过氧乙酸对山毛榉木材漂白测量的所有截面形状都有差异，杉木木材漂白测量的截面形状也有差异。过氧乙酸漂白杉木效果最佳。
主要结果:研究的结果是，1/6稀释过氧乙酸对山毛榉木漂白测量的所有截面形状都有差异，杉木漂白测量的截面形状也有差异。过氧乙酸漂白杉木效果最佳。
亮点:漂白过程使木质材料容易获得均匀的颜色。由于不同截面形状的细胞排列不同，因此漂白率也不同。虽然用草酸漂白木材材料的颜色变化没有太大差异，但样品是用氢氧化钠-过氧化氢和过氧乙酸漂白的结果。颜色变化发生了重大变化。造成这种差异的原因是由于漂白剂的腐蚀程度不同。
