    Journal Article, Paper

    Rad obrađuje problematiku otvorenosti šuma mrežom primarne šumske prometne infrastrukture te dinamiku građenja, održavanja i rekonstrukcije šumskih cesta u Federaciji BiH od 2005. do 2020. godine. Otvorenost šuma u Federaciji BiH još je značajno ispod potrebne minimalne (15 m/ha za brdsko-planinska područja) za racionalno gospodarenje šumskim resursima. Građenje je novih šumskih cesta imperativ za šumarske tvrtke, međutim dinamika izgradnje novih cesta daleko je ispod potrebne razine. Također, rekonstrukcija postojećih šumskih cesta koje su većinom građene 70-ih i 80-ih godina prošloga stoljeća, a čija nosivost nije usklađena sa zahtjevima suvremenih kamionskih skupova, gotovo pa u potpunosti izostaje. Jedan od osnovnih problema za provođenje predmetne analize jest prikaz podataka šumarskih poduzeća u Federaciji BiH, koja rekonstrukciju, održavanje i redovitu sanaciju daju kao jedan podatak, zbog čega realne pokazatelje stvarno izvršenih radova za pojedinačne vrste radova nije moguće na pravi način opisati. Uz kvantitativne podatke koji su dani u radu, također su iskazani i financijski pokazatelji planiranih i realiziranih radova. The need for the construction of new roads, as well as the maintenance and reconstruction of existing roads in the Federation of Bosnia and Herzegovina, is constantly present. The paper analyzes the period from 2005 to 2020, primarily on the basis of regular annual information on forest management in the Federation of Bosnia and Herzegovina, and from survey questionnaires that were conducted in forest enterprises for the preparation of the Forest Transport Infrastructure Development Study (2011) and the Forest Transport Infrastructure Development Master Plan (2020). Activities related to forest truck roads in the forestry of the Federation of Bosnia and Herzegovina have unfortunately shown a delayed trend for many years. The completion of construction works of new roads, as well as regular, periodic maintenance and reconstruction over a period of years, has mostly been below the plan, which specifically refers to the construction of new roads. Based on the analyzed data, a significant difference is noticeable between the planned and built forest truck roads in the analyzed period, where a total of 1213.9 km were planned for construction, while only 592.9 km or 48.84 % of the planned roads were completed. Also, when it comes to invested financial resources, a significantly smaller amount was spent than planned. The planned funds amounted to 41.85 million euro, and 14.75 million euro or 35.25 % of the planned amount was spent. The average investment was 24,879 euro/km. The lowest average costs were in 2014, amounting to 8029.5 euro/km, and the highest in 2009, amounting to 42,297.2 euro/km. There are significant differences when it comes to the openness of forests in FB&H based on data collected in different periods and based on different sources. According to Sokolović and Bajrić (2011), the openness is 10.8 m/ha, according to the data of the Master Plan for the Development of Forest Transport Infrastructure (2020), the openness is 7.83 m/ha, while according to the latest available data from the Information on forest management for the year 2020 and plans for the year 2021, the openness of the forests is 11.3 m/ha. The different results lie primarily in the fact that there is no single criterion for calculating the openness of forests in the Federation of Bosnia and Herzegovina. The openness of all forests in FB&H is not uniform, with the highest average in high forests and according to data from the Information on forest management for 2020 and plans for 2021, the same amount is 16.0 m/ha, in forest plantations it is 9.6 m/ha and in coppice forests 11.2 m/ha. When it comes to the funds invested in regular annual and periodic maintenance, as well as the reconstruction of forest truck roads, they are not shown in the correct way in the forestry operation (all works are shown as a single cost), so it is not possible to give a high-quality analysis of these costs.
