For quality and rational forest ecosystem management the existence of an optimal spatial laid network of primary and secondary forest traffic infrastructure is necessary. There are different parameters for the quantitative and qualitative assessment of the existing network of forest traffic infrastructure as well as to define unopened or insufficiently open forest areas. The relative openness (primary or secondary) in combination with the GIS buffer tools, is a very effective tool in analyzing quantity and quality of primary and secondary forest roads, but also very distinct and descriptive overview of results of the analysis. Research is conducted in management unit “Bovan-Jelar” Forest office Perušić located in the mountainous region of Lika. GIS study area is formed and the cadastre of primary and secondary fo rest roads was established. Analysis of a secondary openness was performed of skidder type Timberjack 240 C equipped with Adler two-drum winch rope length 30, 45 and 60 m. Unopened areas are defined and, in selected subcom partments, for the length of the winch rope of 60 m, the proposed route of the future skid roads that will improve the existing secondary forest roads ne twork. Secondary openness analysis is performed again a and obtained re sults are compared with the current state of secondary openness.
