Sažetak
Selection beech-fir forests cover approximately 157 000 hectares in Republic of Croatia. During the history they have been managed according to different management systems, varying from even-aged to selection management. As a result of historical integration of Croatian forestry into the German forestry school, alongside with unique ecological characteristics of Dinaric area, selection management system has been practiced in Croatia’s forestry ever since. Today, due to various reasons majority of beech-fir forests in Croatia have transitional structure between evenaged and selection structure. It is characterized by large growing stock, small increment, low vitality, poor fir regeneration and increasing share of beech. Example of such case is permanent experimental plot situated in Croatia’s north Dinaric area and managed by Croatian forests Ltd., which is a subject of this research. The aim of this research is to explore different annual cut models which will in future management direct forest into stabile and optimal growth rate in selection structure with aimed volume share of fir. Input data have been acquired from successive measurements on permanent experimental plot in beech-fir stand. Program MOSES was tested for applicability in local conditions and has been used for projecting future stand's growth. Four scenarios based on different cutting models have been used to simulate possible types of future management emphasizing fir natural regeneration, establishment and maintenance of selection structure with targeted volume share of fir versus beech, and also supporting valuable broad-leaved species. Scenarios represent fir volume reduction followed by aggressive beech regeneration and partially accomplishment of selection structure in long-term. Thus, obtained different future stand structures were compared and ranked based on stand attributes and economic indicators. Annual cut based on ideal volume growth rate has been found best scenario from aspects of ecological, management and economic sustainability.
