AB  - The general disproportion of urban development and the socio-economical crisis in Serbia, followed by a number of acute and chronic stressors, as well as years of accumulated trauma, prevented the parallel physical, mental and social adaptation of society as a whole. These trends certainly affected the quality of mental health and wellbeing, particularly on the vulnerable urban population, increasing the absolute number of people with depression, stress and psychosomatic disorders. This study was pioneering in Serbia and was conducted in collaboration with the Faculty of Forestry, the Institute of Mental Health and the Botanical Garden in Belgrade, in order to understand how spending time and performing horticulture therapy in specially designed urban green environments can improve mental health. The participants were psychiatric patients (n = 30), users of the day hospital of the Institute who were randomly selected for the study, and the control group, assessed for depression, anxiety and stress before and after the intervention, using a DASS21 scale. During the intervention period the study group stayed in the Botanical garden and participated in a special programme of horticulture therapy. In order to exclude any possible "special treatment" or "placebo effect", the control group was included in occupational art therapy while it continued to receive conventional therapy. The test results indicated that nature based therapy had a positive influence on the mental health and well-being of the participants. Furthermore, the difference in the test results of the subscale stress before and after the intervention for the study group was F1.28 = 5.442 and p  lt ;.05. According to socio demographic and clinical variables, the interesting trend was recorded on the subscale of anxiety showing that the male participants in the study group were more anxious, with the most pronounced inflection noted on this scale after treatment. The results of this study have shown that recuperation from stress, depression and anxiety was possible and much more complete when participants were involved in horticulture therapy as a nature-based solution for improving mental health.

AB  - Larvae of the gypsy moth, Lymantria dispar L. (Lepidoptera: Lymantriidae), a generalist species, frequently encounter spatial and temporal variations in diet quality. Such variation favoured the evolution of high behavioural and physiological plasticity which, depending on forest stand composition, enables more or less successful exploitation of the environment. Even in mixed oak stands, a suitable habitat, interspecific and intraspecific host quality variation may provoke significant variation in gypsy moth performance and, consequently, defoliation severity. To elucidate the insufficiently explored relationship between gypsy moth and oaks (Fagaceae), we carried out reciprocal switches between Turkey oaks (Quercus cerris L.) and less nutritious Hungarian oaks (Quercus frainetto Ten.) (TH and HT groups), under controlled laboratory conditions, and compared larval performance between the switched larvae and larvae continuously fed on either Turkey oak (TT) or Hungarian oak (HH). We found that larval traits were most strongly affected by among-tree variation in oak quality and identity of the host consumed during the fourth instar. Switching from Turkey to Hungarian oak (TH) led to a longer period of feeding, decrease of mass gain, growth, and consumption rate, lower efficiency of food use and nutrient conversion, and increase of protease and amylase activities. Larvae exposed to the reverse switch (HT) attained values of these traits characteristic for TT larvae. It appeared that the lower growth in the TH group than in the TT group was caused by both behavioural (consumption, pre-ingestive) and metabolic (post-digestive) effects from consuming oaks. Multivariate analyses of growth, consumption, and efficiency of food use revealed that early diet experience influenced the sensitivity of themost examined traits to less suitableHungarian oaks, suggesting the development of behavioural and physiological adjustments. Our results indicate that lower risks of defoliation by gypsy mothmight be expected inmixed stands with a higher proportion of Hungarian oak.

AB  - Although non-wood forest products (NWFPs) are traditionally linked to local communities, they are becoming increasingly involved in the international trade. Identifying the multipurpose character of NWFP is contributed to intensifying their commercial exploitation. The increasing of global demand has enabled the enterprises from Serbia, in accordance with its capabilities, more oriented towards exports of final products of organic food. Fragmented non-standard production in the past, Serbia could not have a significant participation in foreign markets, however, the establishment of different forms of association with the implementation of standards, also including appropriate marketing activities, opportunities for the enterprises to expand significantly. In order to gain insight into the developmental tendencies of local enterprises involved in the purchase, processing and marketing of NWFPs, it has been conducted a survey in order to define trends in their placement. The purpose of this research has been to determine trends in the exports of certain types of raw and value added NWFPs, on the basis of the study samples located in Central Serbia. The goal of this article is to study marketing activities of chosen small and medium enterprises (SMEs) engaged in purchasing, processing and marketing of NWFPs, as well as presenting of current marketing activities of surveyed SMEs and providing of some recommendations for more efficient export in the sector. The main subject of the research is amounts of placed NWFPs in the foreign market. The applied methodology is based on the analysis of time series by trend, which defined the movement in amounts, realized on foreign markets and made projections of exports in the future. The primary method of this study was modelling, while the statistical techniques were used as a method of trend analysis, with the use of regression and correlation analyses. By this study it has been shown the role of efficient market activities in the surveyed enterprises, as one of the important instruments for achieving economic goals.

AB  - Although it is widely considered that the consumption of non-wood forest products (NWFPs) is the result of food industry innovations, from the historical aspect, the use of these products is most likely the first use of forest resources by human beings. The interest in NWFPs as alternative products in the forest sector has increased drastically throughout the world over the last decade. However, in many countries, the maximal commercial contribution of NWFPs has not yet been achieved. In addition to series of economic, social and environmental benefits to society, special emphasis was put on NWFP importance to local communities which rely on NWFPs as the only source of subsistence. The territory of the Serbian Northern Province is characterised by an exceptional richness in wild flora and fauna. However, it is questionable whether NWFPs as important resources are utilized adequately and commercially and consistent with the sustainable potentials and principles. The aim of this study was to identify the flows of the purchase of raw NWFPs and the sale of final products on the research area in Vojvodina. A hypothetical starting point was that an increase is present in the domestic sale of NWFPs. The purpose of the study was to assess the compatibility of the local and the global markets, with a drastic increase in the marketability of NWFPs as the derivatives of organic production. The subject of the study were the enterprises dealing with NWFPs purchase, processing and sale, purchased quantities of raw products, and the contingents of final products realised on the domestic and foreign markets. The applied methodology was based on the dynamic analysis and statistical methods by which the variations in purchased and sold quantities in the past period are defined and the future trend projects are devised.

AB  - Reservoir sedimentation is a serious problem in many areas with high sediment yield. The main objective of this research is to analyse the storage capacity of Drenova reservoir and to determine the quality of water and sediment, particularly the content of heavy metals. Integrated GPS system and echo-sounder were used during the bathymetric survey in order to estimate sediment deposition in Drenova reservoir. The 2012 current state Digital Elevation Model (DEM) was compared to the preconstruction state DEM, which was compiled from geodetic bases and project documentation, thus enabling determination of all changes in the storage of Drenova reservoir. The results of this comparison showed that in the past 30 years, the storage capacity of Drenova reservoir decreased by 262,963 m(3) and 274,342 m(3) based on the normal and maximum water level. Drenova accumulation area is covered with 348,216 m(3) of sediment, which decreased the ineffective space by 69.64% and the total operational space by 5.81%. Water analysis of Drenova reservoir showed usual physical chemical parameters for these types of reservoirs and that it corresponds to maximum allowable concentration for the 11 class water level. The enrichment factor for metal concentrations showed that the anthropogenic influence is moderate for Ni and As, while it is minor for Cr, Cd, Mn, Zn and Cu, and it indicates no enrichment for Pb. The obtained results not only enabled defining potential locations for sediment desilting and its proper disposal in the basin, but led to consideration of other possibilities regarding duration span of Drenova reservoir.

The study shows the variability in all properties among the populations and inter-individual variability within the populations. The variability and differential characteristics were assessed using statistical parameters, taking into account the satisfactory reflection of the hereditary potential. The assessed differences in the vitality and evolution potential of different populations can determine the methods of horse chestnut gene pool collection, reconstruction and improvement.

AB  - The taxonomic status of beech from the Balkan Peninsula is not yet clearly defined. There is no agreement among different authors about the morphological characteristics discriminating between the Balkan and European and/or Eastern beech. For most characteristics, the mean values are different but the ranges of variation overlap considerably. Provenance trial of beech established in Serbia, at the locality Debeli Lug, has provided an opportunity for research of inter-provenance variability at the level of leaf morphometric characteristics in juvenile development stage. Research included 10 provenances originating from the Western Balkans (Serbian provenance 36 and 38; Croatian provenance 24 and 25; Bosnian provenance 30 and 32) and from Central Europe (German provenance 47 and 49; Austrian provenance 56 and Hungarian provenance 42), where following morphometric characteristics were analyzed: leaf length (Ll), leaf width (Lw), petiole lenght (Pl), leaf base width on 1 cm (Blw), number of veins-left (Vl), number of veins - right (Vr), distance between 3(rd) and 4(th) vein - left (Dv 3-4). The results of this research show existence of clear differentiation among provenances from the Western Balkan and from Central Europe, from the point of leaf dimensions, number of veins and leaf base width.

AB  - In recent decades, gathering and utilization of non-wood forest products (NWFPs) have enjoyed a noticeable increase in the interest of both scientific and professional organizations, non-governmental institutions and private sector in Serbia. The Western Balkans have a rich biodiversity with a long history of collection and use of NWFPs and an increasing level of commercialisation. The paper presents an analysis of NWFPs commercialization using value chain method. The analysis is useful in determining the importance of stakeholders or individuals, such as collectors, processors, enterprises and exporters, in driving the trade in NWFPs from Serbia. The objective was to assess the constraints and opportunities for NWFP - based enterprises, and to design more efficient and competitive business solutions by analyzing relationships between chain actors. Primary data were collected through in-depth interview and using open-ended questionnaires with NWFP pickers and processors from around the Serbia. The data were analysed using value chain analysis (VCA), marketing mix, SWOT analysis and analytic hierarchy process (AHP). The results show the most important raw and final products, prices, types of promotion and structure of distribution channels for NWFPs in Serbia. Processors face challenges of a lack of finance, support from state, insufficient processing technology, and poor transport and communication infrastructure.

AB  - Net Present Value and Internal Rate of Return were indicators used in the cost analysis of commercial poplar plantations in Serbia. The study was conducted on four types of sites under plantations of Populus x euramericana cl. 1-214 aged 24-42 years. The aim was to examine the financial results of plantations of different ages at different discount rates. For a discount rate r = 12%, all the tested areas had a negative NPV, regardless of age and site quality. At r = 6%, shorter production cycles to up to 28 years of age on better site classes had positive NPVs (80-580 (sic) ha(-1)), while at r = 4% the investments were financially justified in all cases. IRRs varied in the range 4.32-6.94% at a discount rate of 12%. The best financial results are achieved on the best sites, with the shortest rotation cycles. Determined financial rotation length was 17 years.

AB  - North temperate coniferous forests are known to suffer from root and butt rot caused by Heterobasidion spp., resulting in severe economic losses. Since the mid-twentieth century, various intensities of fungus-inflicted damage have been reported in Scots pine and Norway spruce stands first in the former Yugoslavia and later on in Serbia. Despite the observed damage, the measures taken to protect tree stumps, which serve as an entry for basidiospore infections, have been rare or absent. Sodium borate (borax) has been used at certain locations to prevent Heterobasidion infection following damage caused by wind or snowstorms. This study aimed to compare the efficiency of sodium borate and Phlebiopsis gigailtea to control the establishment of new Heterobasidion infections and to assess the cost of stump protection using these protective agents. Two sites were chosen and both products were applied to the freshly cut stumps. Thirty stumps per treatment and 15 control stumps were analysed at both the sites after 3, 9 and 12 months; therefore, a total of 450 stumps were included in the analysis. The percentages of infection in the borax- and P. gigantea-treated stumps and the untreated stumps were 4, 7 and 20%, respectively. The efficiency of these treatments was very high and ranged from 78% (for borax) to 94% (for P. gigantea). The stump area occupied by P. gigantea ranged from 20-91%, and mycelia could be observed up to 50 cm inside the stumps after 12 months of treatment. The estimated costs of these treatments 5-5.7 Euro cents per stump, depending on the price of the product applied. Thus, the results of this research reveal that stump protection is both ecologically and economically justified.

AB  - In conditions of increasing wood consumption and demand in the world, the aim of the majority of national economies is to intensify local resource production. Due to the fact that poplar rotation is one of the shortest in forestry, and as production of poplar wood requires rational and well-planned management, the potentials of sites and species must be maximally utilised. Favourable financial effects of such a production should be realized. The commercial profitability of poplar cultivation was analysed in an artificial poplar plantation in Serbia. The aim of the study was to validate the invested financial means in artificial poplar plantations, based on the analysis of costs and receipts in different rotation (25-42) years, on different fluvisols (alluvial semigley, humifluvisol, humogley and alpha/beta-beta gley), at different discount rates (4-12%). Methods of analysis of commercial profitability, especially some methods of dynamic investment calculation (net present value - NPV, internal rate of return - IRR, benefit-cost method - R and pay back period - PBP) were used. The investigated plantations were established from Populus x euramericana cl. I-214. with planting spacing 6 x 6 m. Thirteen study plots - management units (55 stands), with a total area of 331.05 ha were investigated in the period 2002-2010. For a discount rate r = 12%, all tested areas had a negative NPV of 11 088 to 23 676 (sic).ha(-1), regardless of age and site quality. The discount rate of 6% can be accepted by shorter production cycles in younger stands (to the age of 28 years) on better sites (alluvial semigley). IRRs varied in the range 4.32-6.94% (average 5.63%) at a discount rate of 12%. Internal rates were larger for plantations on good quality soil types and for shorter rotations and vice versa. The analysis showed that PBP is practically unacceptable for the investor under the discount rate of 6%. The most favourable situation is the discount rate of 2% in younger plantations. The average amount of R was 0.36 for all studied plots.
