Testing the implementation of forest management planning: A decision support for cutting in beech-fir stands of Croatian Dinarides

Forest stands of common beech and silver fir in the Croatian part of the Dinaric area are managed by the selection management system. After the current management plan expires, the whole forest is re- measured and a new plan is created. The most significate segment of future management plan is the prescribed amount of cut, which is determined according to the actual growing stock and the percentage of volume increment. In today’s circumstances of climate change and more frequent appearances of natural disasters (e.g. ice break, snow break), a substantial amount of cut refers to salvage cut and makes the pre-defined plans hard to follow. The simulations of forest growth and management enable the verification of planned management activation through analysis of dynamic development of stand structure. The primary goal of this research is to test an actual plan on a representative Management unit (1, 007 ha) and elaborate on its outcomes until the year 2051 (by using 5, 10 and 15 year-long selection cut cycles). Simulation testing was performed using the MOSES ver.3 simulator. The testing itself revealed end stand characteristics (volume, species composition, increment, dead wood and regeneration). By this point, the second goal of this research takes place ; create the revised management plan grounded and tested on a long-term simulation based on the current forest attributes. Results indicated that when creating a management plan for beech-fir forests in the operative Croatian forestry, the testing via simulations should be performed in order to evaluate plan’s effects on the future forest dynamics.
