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  - 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).
