Making transportation possible in forest areas is essential for forest management to ensure the protection of tree stands (fire access roads, forest monitoring) and use (in situ sales of wood), as well as for tourism and educational purposes. The units of the State Forests National Forest Holding optimize the spatial and quantitative network of roads, but as the manager of the National Treasury's assets, they must ensure that forest roads are in adequate condition. An attempt was made to analyze the technical condition of forest roads based on data from the Information System of the State Forests and to determine their repair and investment needs. Over 50% of all forest roads in the areas managed by the State Forests are still natural, unpaved roads, and 25% of them are considered to be in bad condition. The general technical condition of transportation routes is better, as roads providing unlimited traffic in good and satisfactory condition amount to 43,348 km (41% of all roads). 48% of main roads connected with public roads, which are the primary communication system of forest districts, are in good and satisfactory condition. The analysis shows that 24% (13,000 km) of main roads generally have a dirt surface or improved dirt surface, whereas 5,500 km of roads serving as fire access roads are in bad condition, requiring repair or reconstruction. The use of unpaved surfaces requires maintenance and repair work to ensure the ability to sustain load capacities and parameters enabling use by high−tonnage vehicles for timber hauling and extinguishing fires. It is estimated that on average 5.4% of roads need maintenance work per year, which is equivalent to almost 5,760 km. The quantitative optimization of roads contributed to an increase in the importance and load of the current forest road network, where main roads represent 52% and fire access roads 47%, connected with the need to ensure appropriate technical parameters through the reconstruction of sections of roads.
