Sažetak
This paper analyzes the primary forest openness as an important factor of quality and economy of forest management. Based on the analysis of the existing openness level of forests managed by Hrvatske šume Ltd. (state-owned forests), the aim was to suggest the necessary frame of road construction, up to the level of proposed goals by respective Forest Administrations. Special attention has been paid to the relief conditions and forest function. All forests have been sorted out according to the relief conditions into the following cathegories: lowland forests, hilly forests, mountainous forests and Karst forests. According to the stated cathegories, goals have been determined (on the minimal and so far optimal level): (Tabel 1).
Basic analysis of the existing primary openness has been made on the basis of the management unit, whereby special attention was paid to the relief conditions, and the results are shown by Forest Offices and Forest Administrations. For the openness calculation, the dana of the Forest roads registry of HŠ d.o.o. were used, according to the current methodology proscribed by the Rulebook on Forest Management.
In order to achieve these targets, HŠ Ltd. should construct these figures in management forests:
– Minimum 4354 km
– Optimum 8517 km
In Karst forests (up to the target of 15 km/ 1000 ha):
– 8830 km
The paper also gives a review of forest openness on the level of basic organisational units (Forest offices), which is a very useful piece of information for the company’s investment policy.
