Abstract

Background and Purpose: Regarding official management prescriptions managed fir-spruce forest stands, among others, in Bosnia are supposed to have all-aged structure. We compared the differences between actual and targeted structure in three fir-spruce stands in central Bosnia with special attention given to volume distribution throughout diameter classes. Therefore the aim of the research is to suggest silvicultural measures in order to achieve “ideal” structure on high potential forest sites.
Material and Methods: Collecting of field data was conducted in three managed fir-spruce stands (Abieti – Piceetum illyricum) at Dnolucka mountain in central Bosnia. In each of them by one square-shaped sample area (0.25 ha) was set and inventory data were obtained by following standard procedure for permanent sample plots (total inventory). Data processing was performed by applying basic statistical methods.
Results and Conclusion: It is known that timber overexploitation harms structure of forest stands; on the other hand, as the results in this paper show, scant management intensity doesn’t provide “ideal” structure in fir-spruce stands on high potential sites either. Wood volumes obtained from sample plots in the stands range between 720.6 m3/ha and 976.7 m3/ha, which is quite above “normal” values established for managed all-aged forest stands, and hence neither of them has all-aged structure but rather some of transitional forms of uneven-aged structure.

Keywords: fir-spruce forest, stand structure, site potential, silvicultural measures
