Quality planning of forest road network – precondition of building and maintenance cost rationalisation

The establishing of the optimum forest road network on the terrain consists of the following work stages: planning, designing, building with supervision and maintenance (Pentek et al., 2004). The basic assumption of this research is how to reduce subsequent costs of forest road network building and maintenance by their quality, timely planning and the use of contemporary work technologies (GIS, GPS, computer programmes, etc.) and by the implementation of the adequate truck (haul) forest road categorization. The traffic volume on truck forest roads of economic forests is primarily under the influence of the truck transport of timber assortments (Pentek et al., 2006). According to the truck forest road categorization system based on the analysis of the traffic volume (Nevečerel et al., 2007.), technical features of the individual truck forest road category have been defined. The standard of maintenance within each of separate categories has also been determined. The cost comparison of the currently valid and planned forest opening system has been made on the example of the management unit Veprinačke šume and results were projected on the area of the whole Croatia. The results have confirmed the research hypothesis, so the Study of the primary forest opening, based on the suggested opening system has to become a legal obligation as soon as possible and not, as until now, based on the choice of the individual person.
