SUMMARY: The forest fire-prevention roads are connected with the karst area of the Republic of Croatia which makes about 52 % of its land area and represents the most significant natural feature of the Croatian area. The primary task of karst forests is to fulfil beneficial function of the forest which, by their value, in many ways surpass the value of produced timber, so construction and maintenance of forest fire-prevention roads is financed from the tax of beneficial function of the forest. The research was carried in the area of four forest administrations, as follows: Buzet, Gospić, Senj and Split and the obtained results can be applied to the whole karst area. The definition of the forest fire-prevention roads has been given. The main tasks of forest fire-prevention roads can be divided into three main roads: tasks which contribute to preventive and repressive fight against forest fires, tasks in forest works and tasks in works and activities of users outside the forestry. There was a further analysis within an individual group. Special features of forest fire-prevention roads in relation to other forest roads were analysed in details within six differentiating categories: the approach to the procedure of making a study of forest opening, designing, prescribed technical features, construction and maintenance technology, the price and financial resources and traffic intensity and frequency. The concluding considerations emphasise problems which appear in opening karst forests, but guidelines for their solutions are also suggested. The most important guidelines are defined in the following components: The totality of special features and characteristics of karst, but also special features of karst forest growing in that area, produced a forest fire-prevention road as a special forest road category with all its specific qualities in all the stages of opening of karst forests. Despite the "non-economical" construction of forest fire-prevention roads regarding the raw base of karst forests, these forests have to be systematically opened till achieving the optimum/aimer openness due to their fire-prevention role, production potential, beneficial function of the forest and all other management segments. The valorisation of generally useful characteristics of forests will enable the use of cost models in calculating optimum/aimed forest openness, but will |
