AB  - This research was carried out in a selection stand of beech and fir, where logging was performed with chainsaws of different powers. Two chainsaws of 3.9 kW were used for work on one area, while on the other one the applied tools were a combination of a smaller and a larger saw (2.5 kW and 3.9 kW). After logging, the consumption of energy products (fuel (gasoline and motor oil mix ratio 50:1) and chainsaw oil) was measured for each individual chainsaw by the method of refueling. It was found that the power of the chainsaw, i.e., the combination of chainsaws of different powers, significantly influences the consumption of energy products in a beech-fir mixed stand. By using a combination of one larger and one smaller chainsaw instead of two larger chainsaws, savings of about 26% for fuel and 24% for oil were achieved. The prediction analysis found that by using two chainsaws (of lower and higher power) instead of two higher power chainsaws (currently common mode of work) in beech stands for an estimated volume of about 1 million m(3) year(-1), the savings could be about 54,000 L of fuel and about 19,000 L of oil. In monetary value, this is a saving of about EUR 120,000 year(-1), i.e., of about 2,500,000 MJ year(-1) of energy.

AB  - Planning forest truck roads network involves a lot of factors that directly affect their density and length. Depending on the purpose of the forest truck road network, this number is higher or lower. Our opinion was that these factors should be divided into invariable and variable. Common parameters, regardless of the purpose of the roads, are morphometric parameters because they can limit the length and density of the network of forest truck roads due to their variety of forms. For this reason, this paper deals exclusively with the morphometric characteristics of the terrain and their influence on the density of the network of forest truck roads. The DEM of the terrain was processed with GIS software based on the seven most important influencing factors. By standardizing the criteria, the obtained maps were reclassified, and then each of the seven selected parameters was weighted with the coefficients obtained by the AHP method. In this way, a map of the suitability of the terrain for the construction and addition to the existing network of forest truck roads was obtained. The terrain is divided into 4 categories of suitability. Zero lines were drawn with GIS tools for road design. During the creation of the optimal road network, it was tested with absolute and relative openness. As a final result, each of 26 Forest Economic Areas (FEA) was assigned to one of 4 categories of terrain suitability for the construction and density of the forest truck road network. For each category of terrain convenience, the optimal absolute and relative openness is shown. Based on this work, we suggest that the use of morphometric parameters should be considered as the first step of forest road planning in other regions.

AB  - Forest road construction in protected areas is one of the most pronounced anthropogenic activities. In order to reduce the negative impacts of forest roads on the environment, the planning of a multi-functional network of forest roads must be approached in a planned way, taking into account a number of aspects. The paper selects seven most influential criteria for determining suitable locations for forest road construction in a protected area using the Delphi method. A part of Fruska Gora National Park in Serbia was chosen as the research area. The invitation was sent to 36 experts, and 32 participants accepted the invitation. The group of experts found that the most influential criteria are: fire risk, transportation distance, connection with populated areas, wood volume, felling volume, presence of water springs and terrain slope. The average number of points ranged from 70.35 for the criterion "terrain slope" to 85.35 for the criterion "fire risk". The largest number of criteria selected in the Delphi procedure belong to the group of economic criteria, although the forests are located in protected areas.

AB  - Planiranje finansijskih sredstava za izgradnju šumskih kamionskih puteva u većini slučajeva planerima zadaje poteškoće. U šumskoprivrednim osnovama postoji podatak koliko je godišnje potrebno izgraditi puteva za naredni uređajni period sa prosečnom cenom izgradnje, međutim taj podatak je dosta uopšten i bazira se na iskustvenim procenama. Cilj ovog rada je utvrđivanje prosečne cene izgradnje šumskih kamionskih puteva u Republici Srpskoj, kao i utvrđivanje prosečne cene pojedinih faza rada. Analizirajući 71 glavni projekat u 11 šumskoprivrednih područja, čime je obuhvaćeno 178 km šumskih kamionskih puteva, dobijena je prosečna cena izgradnje šumskih kamionskih puteva od 32.490,87 €/km. Dobijeni rezultati ukazuju na činjenicu da je izgradnja šumskih puteva najskuplja u brdovitim predelima sa nadmorskom visinom između 200 i 500 m (34.298,28 €/km), dok je najjeftinija (30.922,88 €/km) u srednje planinskim predelima, s visinama između 1000 i 2000 m.
AB  - In most cases, the planning of funding for the construction of a forest truck road causes difficulty to planners. Although a forest management plan (FMP) indicates the number of roads to be built annually for the next development period with the average cost of construction, this information is quite general and based on experiential estimates. The aim of this paper is to determine the average cost of forest truck road construction in the Republic of Srpska, as well as to calculate the average costs of individual phases of operation. The obtained average cost of forest road construction, resulting from the analysis of 71 major projects in 11 forest areas encompassing 178 km of forest roads, is 32,490.87 €/km. The obtained results point to the interesting fact that forest road construction is the most expensive in hilly areas with an altitude ranging between 200 and 500 m (34,298.28 €/km), while it is the cheapest (30,922.88 €/km) in medium mountainous areas, with altitudes between 1000 and 2000 m.

abstract = "Planiranje finansijskih sredstava za izgradnju šumskih kamionskih puteva u većini slučajeva planerima zadaje poteškoće. U šumskoprivrednim osnovama postoji podatak koliko je godišnje potrebno izgraditi puteva za naredni uređajni period sa prosečnom cenom izgradnje, međutim taj podatak je dosta uopšten i bazira se na iskustvenim procenama. Cilj ovog rada je utvrđivanje prosečne cene izgradnje šumskih kamionskih puteva u Republici Srpskoj, kao i utvrđivanje prosečne cene pojedinih faza rada. Analizirajući 71 glavni projekat u 11 šumskoprivrednih područja, čime je obuhvaćeno 178 km šumskih kamionskih puteva, dobijena je prosečna cena izgradnje šumskih kamionskih puteva od 32.490,87 €/km. Dobijeni rezultati ukazuju na činjenicu da je izgradnja šumskih puteva najskuplja u brdovitim predelima sa nadmorskom visinom između 200 i 500 m (34.298,28 €/km), dok je najjeftinija (30.922,88 €/km) u srednje planinskim predelima, s visinama između 1000 i 2000 m., In most cases, the planning of funding for the construction of a forest truck road causes difficulty to planners. Although a forest management plan (FMP) indicates the number of roads to be built annually for the next development period with the average cost of construction, this information is quite general and based on experiential estimates. The aim of this paper is to determine the average cost of forest truck road construction in the Republic of Srpska, as well as to calculate the average costs of individual phases of operation. The obtained average cost of forest road construction, resulting from the analysis of 71 major projects in 11 forest areas encompassing 178 km of forest roads, is 32,490.87 €/km. The obtained results point to the interesting fact that forest road construction is the most expensive in hilly areas with an altitude ranging between 200 and 500 m (34,298.28 €/km), while it is the cheapest (30,922.88 €/km) in medium mountainous areas, with altitudes between 1000 and 2000 m.",

AB  - Stump removal is a regular measure of terrain preparation during the establishment of poplar plantations. It is implemented in order to increase the efficiency of implementation of regular silvicultural measures, but also the efficiency of comprehensive wood mass utilization. Stump removal in poplar plantations is performed by various facilities, including various types of wood chippers attached to a tractor of certain technical characteristics. The aim of this paper is the evaluation of efficiency of the tractor “Same Laser 150” with the wood chipper “Rotor S” attached to it, during the stump chipping of soft and hard broadleaves in various operating conditions. The research was carried out in several sample plots located in an area managed by the public enterprise “Vojvodina šume”. The differentiation of the operating conditions was based on multiple criteria (distance between stumps, level of forest order establishment, carrying capacity of the ground, percentage share of tree species, etc.). The work effects of stump chipping were established using the work and time study. The duration of stump chipping ranged from 0,82 min/stump to 2,29 min/stump and it depended on stump diameter, root system development, diameter of the auger used for stump chipping, tractor power, etc. In addition to being dependent on some other things, chipping time depends on the number of passes and auger diameter. The time of transition from stump to stump is under the highest impact of ground conditions, which implies the amount of wood residue, the presence of stump shoots, and the occurrence of high weeds. The implemented analysis served as the basis for the ranking of the factors depending on their impact on the work effects of the investigated facility. In addition, it was concluded that greater effects can be achieved by using the command that provides a forward and backward movement of the aggregate without pushing the clutch pedal and pulling the gearshift lever, but also by installing a handle for the change of rpm (revolutions per minute) of the output shaft in the driver’s cabin. This handle is currently located on a differential housing next to the left wheel, so the driver has to leave the cabin to change the rpm of the output shaft. Another problem is that the tractor “Same Laser 150” has double commands installed in the cabin: the clutch, brake and gas pedal, but when the seat makes a 180 degree turn those pedals are not at the adequate height. In addition to that, the operator does not have enough space for work in the tractor cabin. An increased cabin space and a better position of the above mentioned commands would enhance work efficiency.

AB  - The focus of this paper is on the description of the openness of primary forest traffic infrastructure in the Republic of Srpska. The data were collected using Garmin Oregon 600 GPS devices across the entire territory of state forests, managed by the Public Enterprise, Sume Republike Srpske", and the recorded traces were compared and corrected by orthophoto snapshots with a 0.50 m resolution. The tools used for the processing of collected data were software ESRI ArcGIS 10.2 and Quantum GIS 16.2. In addition, the analysis covers all forest roads that pass through state forests that can be used for forest management and enable the movement of trucks. Public roads are only taken as an overview of openness of this category of roads and forest openness is shown by forest categories. The analyses included 843,466.00 ha out of the total of 1,002,056.00 ha of state-owned forests. The final aim of this analysis was to obtain a clear insight into the quantitative status of primary forest traffic infrastructure in the Republic of Srpska. The data were collected during 2016. Based on the analysis, the total density of the network of primary forest traffic infrastructure for the research area was 9.28 m/ha without public roads, i.e. 11.21 m/ha with public roads. In addition, density of the network of primary forest traffic infrastructure was determined separately for each category of forests, and the highest density of forest road network was found in forest plantations (11.57 m/ha or 14.82 m/ha with public roads) and high forests with natural regeneration (11.13 m/ha or 12.49 m/ha with public roads).

AB  - This paper presents a multi-criteria selection of the best forest road network with the aim of achieving effective preventive and timely repressive protection against forest fires. The research was carried out in national park (NP) "Tara" at a site which is under constant threat of fire. Four variants of the forest road network were designed and analyzed against seven criteria, and the best variant was selected using entropy weight coefficients (EWC) method. The importance of these seven criteria was studied by the management of the NP "Tara." The greatest importance was given to the criteria relating to the cost of construction and maintenance of permanent and temporary roads (47% of the total value of all criteria). The EWC method did not select the variant based on the lowest costs of construction and maintenance as the best option, but the variant whose location was the most suitable for effective defense against forest fires.

AB  - Designing of forest roads involves the performance of many specific tasks. Each of the tasks requires the expertise and the use of appropriate tools. There are many computer programs that are used for designing public roads and forest roads. This paper shows the comparerison of the existing solution, the computer program »Cesta« (Road) and the modern computer module »Trasa« (Route). Possibilities of each tool are shown and their functionality is tested on specific examples. The computer program »Cesta« is often used in Croatia and its possibilities are very well known among designers of forest roads. The paper presents the main views (situation, longitudinal profile, cross sections), and additional tools that are rarely used for designing forest roads. Deficiencies cannot be removed because the computer program »Cesta« ceased to develop, and it is, therefore, difficult to adjust to possible changes in legislation and technical requirements for forest roads. On the other hand, the computer module »Trasa« is a new tool for us that is still evolving in line with the needs of the user. The paper describes the structure and function menus required for the master/detailed design of forest roads. The working principle is explained and new solutions are presented that can make the computer module »Trasa« a potentially better solution if its design methodology is adjusted to new technologies. Designers of forest roads have always made efforts to upgrade the quality of designing forest road, trying to introduce uniformity and standardization, and it is up to them to choose an appropriate solution.

AB  - Smooth movement of vehicles on forest roads necessarily requires widening of
   the traveled way in small radius curves. This paper presents the results of a
   comparison of two methods for determining the required widening of a forest
   road traveled way in small radius curves: the traditional method based on
   formulas and the traces curve method, obtained by simulating the movement of
   vehicles. Both methods were applied in the preparation of the Main project of
   reconstruction of the forest road “Rasadnik - Pustinac” with a length of
   5.285 km in the teaching base of the Faculty of Forestry “Majdanpečka
   domena”. In the project which determined the traveled way widening by the
   traces curve method, the total area of the surfacing was by 2.79% smaller
   than the area of the surfacing in the project which determined the widening
   using a formula. The width of the traveled way directly affected the scale of
   earthworks. In the first case, the volume of the cut was by 4.17% lower than
   in the second one. The volume of the filling decreased by 7.05%, and the
   amount of material needed for making the surfacing decreased by 2.94%. A
   smaller volume of earthworks and material required for pavement construction
   in the preparation of the Main project of reconstruction, in which the size
   of widening was calculated by the traces curve method, influenced the
   estimated value of reconstruction is lower by 3.34% than the total cost of
   reconstruction obtained in the preparation of the Main project of the same
   forest road reconstruction that calculated the widening size using the
   traditional method.

AB  - The effects of roads and railways on major species of large game (roe deer and wild boar) have been studied in eight hunting grounds in the Belgrade area (nine municipalities), as well as the consequences of chemical accidents in transport of hazardous materials. Road accidents involving birds, game and other animals (WVC - wildlife vehicle collisions) during 2009-2013 in the Belgrade area result in 10 cases (4.8%) in injuries for drivers and passengers. In total, 267 roe deer and 8 wild boar were killed in traffic by cars and trains. Traffic accidents with roe deer have their maximum in April-May and then in December. The adult sex ratio in roe deer killed in traffic by cars and trains was 2.1 (173 female and 80 male), indicating that females were more vulnerable than males. The yearly traffic kill of roe deer represented between 0.8% and 1.1% of the spring population size. In the Belgrade area, the mobile eco-toxicological laboratory of the City Institute of Public Health Belgrade during 2004-2012 registered 177 chemical accidents (mean = 19.7, range = 13 to 26). The chemical accidents in transport of hazardous materials were sporadic and their consequences were small-scale contamination of the environment and economic losses. At the main transport routes of hazardous materials passing through hunting grounds in the Belgrade area occurred 26 chemical accidents, out of which 11 on the railways and 9 on the roads, and the remainder in air and river transportation (4 and 2, respectively).

AB  - This paper presents an analysis of damage to residual trees and the regeneration that occurs during harvesting using the half tree length method and timber extraction in winter operating conditions in a pure beech stand and a mixed stand of beech fir and spruce in the territory of the Srpska Republic. In this study, types of damage were investigated, as well as the size of wounds. Felling and processing of wood assortments were performed with a chainsaw and timber extraction on earth and by skid trail to a roadside landing on a truck road was performed with a tractor Timberjack 240C. The number of injuries that occurred during the felling and transport of trees in the mixed stand was on average 2.69 wounds per felled tree, whereas in the pure stand the average number of wounds per felled tree was 2.27. During the felling of trees in both sample plots, the largest number of injuries was to the crowns of neighbouring trees, which was followed by damage to the butt end, whereas the lowest number of injuries was incurred to the root collar. During the timber winching, the most common damage was to the root collar, whereas during timber skidding the most common type of damage was to the butt end. Damage to the regeneration was evident in both sample plots in the form of breakages of plants and their branches, as well as uprooting of whole plants. Damage to the butt end and root collar that occurred at the felling stage was in the form of bark peeling and other superficial wounds whose most common sizes were larger than 200 cm(2). The average area of injuries caused during the transport phase ranged from 50 to 200 cm(2).

AB  - Planiranju mreže šumskih puteva prethodi detaljna analiza trenutnog kvalitativnog i kvantitativnog stanja šumskih puteva, a pre svega, utvrđivanje njihovog prostornog rasporeda. U radu je izvršena kategorizacija i ocena stanja postojećih puteva u GJ 'Željin' i 'Bukovik II' i definisanje delova gazdinskih jedinica sa nedovoljno rezvijenom mrežom šumskih puteva. Izdvajanje neotvorenih i nedovoljno otvorenih delova gazdinskih jedinica izvršeno je na osnovu gustine mreže šumskih puteva po odeljenjima i po mreži čije su ćelije dimenzija 500 x 500 m, a zatim i na osnovu omeđenih površina sa različitim širinama pojaseva oko šumskih puteva. Apsolutna gustina mreže šumskih puteva u GJ 'Željin' iznosi 18,62 m/ha, a u GJ 'Bukovik II' 12,03 m/ha. Postavljanjem omeđenih površina oko šumskih puteva, utvrđeno je da je u GJ 'Željin' preko 56% površine pokriveno pojasom širine od 0 do 200 m, dok u GJ 'Bukovik II' ovaj pojas pokriva 48% površine.
AB  - The planning of a forest road network is preceded by a detailed analysis of the current qualitative and quantitative state of forest roads, and above all, the determination of their spatial layout. This paper presents a categorization and assessment of the state of the existing roads in the FMUs 'Željin' and 'Bukovik II' and defining of the parts of management units with insufficiently developed networks of forest roads. The identification of unopened and insufficiently opened parts of management units was performed on the basis of density of a forest road network by departments and using a fishnet with 500 x 500 m cell dimensions and buffer zones of different widths around forest roads. The absolute density of a forest road network in the FMU 'Željin' is 18.62 m/ha and in the FMU 'Bukovik II' 12.03 m/ha. After placing buffer zones around forest roads, it was found that in the FMU 'Željin' over 56% of the area is covered by the zone ranging from 0 to 200 m, while in the FMU 'Bukovik II' this zone covers 48% of the area.

AB  - This article presents the results of a research dealing with operating efficiency of articulated and tractor assemblies in the plots of poplar plantations in which different means of work were used for felling and cross-cutting. The aim was to study the effects of the arrangement of wood assortments on the driving speed of the vehicle, the time needed to load and manipulate the vehicle and the overall working efficiency of forwarders. The research was carried out in Vojvodina, in the area of PE »Vojvodina šume«. Altogether 170 transport cycles were recorded and 2166.73 m3 transported. The research results show that the forwarder moved faster on the felling site where the felling and cross-cutting operations were carried out by a harvester. The speed was 10% higher and it took 5% less time to load the forwarder. The differences were considerably greater concerning the manipulation time (maneuvering and positioning the vehicle during the loading). The driving speed decreased with an increase in the load volume. Fuel consumption was lower in the felling site where a harvester was used for felling. Under the same working conditions, the tractor assembly achieved better productivity because it drove at considerably higher speeds. The differences in the average load volume were not so great, which significantly affected the productivity of the tractor assembly. The initial hypothesis that a forwarder achieves better working efficiency in the felling site, where a harvester has been used in the operations of felling and cross-cutting, was confirmed.
