Sažetak
A basic requirement in today's forest resources management is an ongoing production of all forest utilities with preserving the forest ecosystem stability. Considering the even-aged forest management, this requirement will be assured by achieving compositions of normal and stable forests based on normal age class order. Faced with natural systems governed by intricate relationships in time and space, we have chosen a system-dynamic modelling as our work method, and projected a simulation model of even-aged forest management process by applying the method of age class distribution. After simulating suitable scenarios, we focused our research on the future development of age class distribution per area and growing stock on the management unit "Josip Kozarac", within the pedunculate oak management class. The simulation research proved that even-aged forest management, defined by the intensity of regeneration felling (i.e. by the method of calculating the felling area of the major harvest cut) and the length of rotation, is a powerful factor affecting the future behaviour (i.e. the change of age class distribution, felling areas growing stock and values) of a closed even-aged forest system.
