Description:
<jats:p>Optimization of primary forest accessibility is observed from the point of intensity of forest management and terrain relief conditions of the forest area. Optimization of primary forest accessibility is the first phase of the planning of primary forest traffic infrastructure. The second phase is designing of new primary forest traffic infrastructure. The high forests with natural regeneration (high forests) in the public forests are selected for optimization of accessibility because they are the most valuable forest category from the point of quantity and quality of timber. Planning of primary forest traffic infrastructure implies analysis of actual primary forest accessibility of high forests, determination of optimal density of primary forest traffic infrastructure, defining of suitability of high forests area for construction of primary forest traffic infrastructure and upgrading of actual primary forest traffic infrastructure with new routes of primary forest traffic infrastructure. Optimization of primary forest accessibility in hilly and mountainous high forests was done in two Management Units, Prosara and Bobija-Ribnik. Optimal density of primary forest traffic infrastructure ranges from 24 to 26 m/ha. Results showed that high forests have potential for sustainable forest management.</jats:p>
