AB  - The aim of this paper is to analyze the effect of different degrees of mixing on the diversity structure in stands left to spontaneous development. The research included two communities of species endemic to the Balkan Peninsula-the Serbian spruce (Picea omorika Pancic Purk.) and the Macedonian pine (Pinus peuce Griseb). Data from eight sample plots were used in the research. The changes in diameter and height structure, spatial arrangement of trees, and diameter differentiation were analyzed. The analyzed parameters of structural diversity show relatively low to moderate values. Results showed an increase in mixing was reflected in the width and shape of distributions. A spatial analysis of stands with a higher degree of mixing showed a tendency towards a random to regular distribution of individuals, in contrast to stands with a lower degree of mixing which showed a tendency towards a clump distribution. The pronounced species' dimensional and spatial diversity confirms their importance to the condition of modern forest management. Significant differences in the change of structure are shown by stands with a share of admixed species of above 20% by volume. The obtained results refer to stands left to spontaneous development, suggesting than an active research and management approach must be assumed to realize the goal of protecting rare forest ecosystems.

AB  - The research presented in this paper deals with mixed spruce and fir forests of the "Đerekarski Omar" and "Mojstirske Šume" management units that belong to the Gornji Ibar forest area. The investigated stands belong to the community of spruce and fir -Abieti -Piceetum abietis Mišić et Popović, 1978. The structure and production potential of these forests were studied using data collected in two experimental fields that are 1 ha and 0.5 ha in size. In terms of the structure, the investigated stands are even-aged, although they may be expected to acquire characteristics of two-story stands in the future. The general characteristic of spruce and fir forests in this forest area is great structural diversity, ranging from even-aged stands to multi-storey and all-aged stands. At the same time, small and medium 1 Nikola Martać, master inž. šumarstva, student doktorskih studija; dr Nenad Petrović, docent; dr Branko Kanjevac, asistent sa doktoratom; Aleksandar Popović, master inž., istraživač -pripravnik, Univerzitet u Beogradu Šumarski fakultet, Beograd "ŠUMARSTVO" 1-2 144 diameter trees dominate, with a minimal presence of trees of large dimensions. The site potential, stand characteristics, and interspecies relationships in the stands have resulted in a complex structure, high productivity, and ecological stability of these forests. Therefore, radical measures and thinnings that would disrupt the established relationships and dynamic processes should be avoided in future management.
