Dinamika uspostave preborne strukture u bukovo-jelovim sastojinama na Papuku

Diameter class distribution data, as well as diameter increment and increased number of trees, provide a basis for the simulation of stand development. With advances in computer technology, modelling and stand development research has shown increasing importance. The objective of this paper is to explore the establishment dynamics of a selection stand structure in mixed beech-fir forest on Papuk. In the past, these forests were managed as even-aged forests. The research was carried out in the Management Unit Zapadni Papuk Zvecevacki, Kamenska Forest Office. Using the data from forest management plans (plans of 2006, 1996 and 1986), ten stands were selected for which dynamics simulation of conversion into uneven-age stands was performed. The stands were selected on the basis of age, tree diameter distribution, density and mixture. After simulation, sub-compartments 34b, 42b and 56a were selected for display. The data for these stands are shown in Table 1.
