Reforestation of technologically polluted areas has become an increasingly important issue. In this study, seed germination capacity and survival rate and morphometric characteristics of Scots pine (
...Pinus sylvestris
L.) seedlings grown in a magnesite-polluted soil medium were investigated in a pot experiment. Significant differences in seed field germination, sprout survival, seedling length at various growth stages, and root collar diameter of the seedling were discovered between the trial variants for the pot trial using growing media from the polluted areas and the control site. In addition, it was observed that the differences between the trial variants depended on seed origin and the level of soil pollution. The data indicate that seed germination and seedling growth were significantly reduced as the levels of pollution increased. These negative effects of the pollution tend to increase as the seedling gets older.
The rising temperatures and decreasing rainfall are expected to have negative effects on ecosystem services by causing significant shrinkage or shift of forest distribution particularly in ...Mediterranean basin. In this study, it was aimed to determine the distribution of oriental beech (
Fagus orientalis
Lipsky.) by modelling the current and future potential locations of the habitats. With Maximum Entropy (MaxEnt) approach, we predicted its distribution under current and future conditions (RCP 4.5 and RCP 8.5) in Turkey. Modelling was performed by using eight bioclimatic variables that show significant relationship to the current distribution of oriental beech and were widely used in the literature. The fitted model had high quality (93.5% AUC) and is biological meaningful. The prediction of warmer condition in future showed that the populations on the southern slopes of the North Anatolian Mountains were expected to shrink and that there would be reduction in the populations found in the main distribution area in the Istranca Mountains and the Northern Anatolia, especially in populations in the transition zone of Central Anatolia. Also, oriental beech would lose its isolated-marginal populations in the southeast of Turkey. The results highlight the importance of a genetic conservation programme for beech population in Turkey. Otherwise, the genetic pools seem to extinct under climate change. Furthermore, the paper is intended to provide a starting point for a monitoring of oriental beech at the edge of its distribution, to observe its climatic migration.
In Turkey, almost half of which has semi-arid conditions, steppe areas have continuously been increasing. These areas need to be afforested to prevent desertification. For this purpose, this research ...presents specifically the Anatolian black pine (Pinus nigra J.F. Arnold subsp. pallasiana /Lamb./ Holmboe) as a suitable forest tree species for afforestation activities, due to wide distribution both in Turkey and the broader region. After a thorough investigation of past and recent literature, and onsite activities, the review focuses on the production of seeds and seedlings of the species, land preparation and planting technique, post-planting site maintenance, success in the afforestation areas and considerations on Anatolian black pine seed transfer regioning. In conclusion, local ecological conditions regarding the species should always be taken into consideration. Another important issue for the success of afforestation in semi-arid lands is that the preparation activities of the land for afforestation are carried out with appropriate techniques timely and painstakingly. Moreover, after the 2000s, Turkish forestry focused on afforestation in semi-arid and anthropogenic steppe areas. Anatolian black pine is the most widely used tree species in semi-arid lands and anthropogenic areas and plays the major role in successful afforestation.
This study aims to analyse and map the network structure of the scholarly communications in the realm of forestry research between 1999 and 2019 in Turkey using bibliometric analysis and social ...network analysis methods of the articles published within Clarivate Analytics’ Web of Science (WoS). A total of 8689 records, including their bibliographic data, were extracted from WoS. The analysis of each sub-period shows that the number of international collaboration of Turkish authors has increased globally from 23 countries in the first sub-period to 113 countries in the last sub-period within forestry publications. Also, the annual percentage rate of publications has increased from 58 articles in 1999 to 1016 in 2019 in the realm of forestry alongside with their received average citations in each sub-period. Multi-author articles precede single-author articles in the field of forestry in each sub-period. This research is the first analysis of forest research production using bibliometric and network analysis in Turkey. According to the results biomass, remote sensing and climate change were current trends on forest research in Turkey. Incidentally, the research findings can be used by policymakers regarding future investments in forestry research development.
The article presents the results of assessing the element mobility (chemical elements and compounds) from the copper smelting slag recycling waste into brown forest soils (Haplic Cambisols) of the ...southern taiga district in Middle Urals, Russia. The copper smelting slag recycling waste was obtained by crushing the cast slag of the Sredneuralskiy Smelter (“technical sand”) followed by flotation extraction of copper concentrate. The investigations were carried out in two forest types, distinguished according to the principles of the genetic forest typology, cowberry shrub pine forest and berry pine forest with linden, and the corresponding clear-cuttings. We conducted the experiment in the autumn before the snow cover was established in two variants: (i) we evenly scattered 1 kg of waste on meter sample plots; (ii) we weighed the “technical sand” by 100 g, packed it in non-woven material and buried it in the soil to a depth of 7–10 cm. Two years later, we dug up the bags with waste and weighed them. The analyses were performed by inductively coupled plasma mass spectrometry using Elan-9000 ICP mass spectrometer. As a result of the research, it was found that waste loses 11% mass over 2 years of being in forest soils. The content of Zn, As, Cd, and Se changes most strongly. The difference in the degree of element migration from the “technical sand” to the brown forest soils of the two forest types and clear-cuttings was revealed. The study of the effect of technogenic waste on the dominant and diagnostic species of grassy vegetation in the selected forest ecosystems of the Middle Urals was carried out. There was no negative effect on the qualitative composition of the grassy layer of two forest types and their clear-cuttings after 1 year after a single surface application of mineral waste at a concentration of 1 kg/m

This study was conducted in the afforestation area, using bare-root 2+0-year-old Scots pine seedlings from Kastamonu. The study aimed to determine the impact of nanoparticle (NP) applications on ...seedling morphological characteristics and seedling survival success. Three different concentrations (low, medium, high) and four different nanoparticle types Fe₃O₄, CuO, ZnO, TiO2 were applied to the plant root-dipping method in the study. The effects of NP treatments on seedling height (SH), root collar diameter (RCD), stem fresh weight (SFW), root new weight (RFW), seedling fresh weight (SEFW), root dry weight (RDW), stem dry weight (SDW), seedling dry weight (SEDW), sturdiness quotient (SI), root: shoot ratio (R/S), and seedling survival in the field were evaluated. The study results revealed that NP types significantly affected all seedling variables except RFW, SDW, RDW, and SEDW, and NP doses significantly affected all seedling variables except RFW. The binary interaction effects of NP types and doses had a significant effect on all seedling variables, and higher values were obtained compared to the control treatment. Medium and high NP doses were more effective in seedling growth than low doses; the percentage of seedling survival was 61.4% in the control treatment and 95% in the TiO2-Medium NP treatment combination.
Melatonin, a substantial hormone, is a natural antioxidant agent that functions as a protector against the harmful effects of free radicals. Studies have found that “exogenous melatonin” applications ...have a positive effect on the growth and development of plants. This study investigated the adaptation of the seedlings that were transported from the nursery to the afforestation site for the process of planting. In 2019 the 2+0 aged bare-rooted Kastamonu/Taşköprü Anatolian Black pine seedlings, which are suitable for planting in semi-arid areas, were selected as research materials. Four different doses of “exogenous melatonin” (250, 500, 1000, and 1500 μM) were administered through two different methods (root-dipping and needle-spraying). Morphological seedling characteristics and bioactive chemical variables were measured for the control group and the seedlings treated with different doses of melatonin. Antioxidant enzyme activities were identified. When both the needle-spraying and root-dipping methods for melatonin application were evaluated in terms of morphological and biochemical variables, the best results were determined in low doses (250 to 500 μM). The results suggest that melatonin provides support to the metabolic process for the resistance of seedlings to low temperatures and semi-arid climatic conditions.
The aim of this paper is to present the intraspecific differentiation of the curly silver fir (Abies alba Mill.) by the wood structure growing in the Ukrainian Carpathians. To find the morphological ...distinctions by using the silvicultural and biometric methods, 50 silver fir trees with anomalous wavy-relief stemwood formations were investigated. The trees aged from 94 to 132 years were characterised by the diameter at breast height of 32–59 cm. The length of the wave-grained stemwood varied from 6 to 11.5 m. The amplitude of the wood fibre waves varied from 4.4 to 24.1 mm. The smallest values of the amplitude of the wave-grained wood corresponded to the smaller wavelengths. The significant differences in the wood density and annual growth between the silver fir trees with the straight-grained and wave-grained stem wood were determined. The number of annual rings in 1 cm of the curly silver fir was 27.1% lower and 22.7% higher than the same characteristics for the straight-grained stem wood. The obtained linear equation described the relationship between the number of annual rings in 1 cm and the basic wood density of the silver fir with the straight-grained wood. The aesthetic features of the curly silver fir stem wood were discussed in the subject area of a new niche of exclusive wood products.
The present study is focused on the potential distribution of the Lebanese cedar (
Cedrus libani
) in the present and in the future throughout the twenty-first century. The location of this work ...encompasses Lebanon, Syria and Turkey. Twenty-four environmental variables are used and two Representative Concentration Pathways (RCP) scenarios for two different time periods are studied: RCP 4.5 2050, RCP 4.5 2070, RCP 8.5 2050 and RCP 8.5 2070. The most interesting novelty is the use of 13 General Circulation Models and 6 algorithms (Climate Space Model, Envelope Score, Environmental Distance, Genetic Algorithm for Rule-set Production, Maximum Entropy and Support Vector Machines) were considered for modelling. Area Under the Curve is used as goodness of fit and building the final consensus map. The global habitat suitability area would enlarge in the forecasted scenarios with respect to the present, although it would be more restricted in 2070 due to the altitudinal shift. This study also suggests an interesting approach to manage
