Sažetak

Common beech (Fagus sylvaticaL) is the most videly distributed tree species in Croatia. Because of its physiological and ecological characteristics (high shade tolerance, ability to grow on a broad range of soil types, topographic positions, and climate conditions) common beech in Croatia forms different stands, from pure to mixed stands with different tree species, and with different structural characteristics. Characteristics of beech to oncoming in a wide range of different ecological and management conditions, and to creates stands of different structural characteristics, causes an increasing deviation of the structural elements values of managed stands in compare with values of the same stuctural elements that are tabulated in yield tables. Therefore there is need for investigation of structure of beech stands and applicability of yield tables at the local level for common beech and the other species that form beech stands.
The aim of this work is to research the basic structural elements of the managed beech stands and to compare them to the tabulated values in growth-yield tables, by local authors.
Field measurements were conducted on 449 circular plots located in 18 compartment in IV and V age classes in management unit Đurđevačka Bilogora. Intensity of sampling was 5% of a total area of selected compartments.
As expected, the results in this research show deviations in compare to tabulated values in yield tables, by local authors. Results show the complexity of problems in management with beech stands and need for local level approach in order to improve the distribution of age structure, product quality and sustainability of revenue on both local and global level, considering the purpose, method and management type of beech stands.
