DIVERZITET, STRUKTURA I TEKSTURA PRAŠUME I GOSPODARSKE ŠUME BUKVE I JELE SA SMRČOM NA GRMEČU U ZAPADNOJ BOSNI

UDK 630*2:630*4/.5(253)(497.6 Grmeč) The research of the diversity, structure and texture was performed on the mountain Grmeè in western Bosnia, in the summer and fall of 2007, in the virgin forest and in the managed forest of beech and fir with spruce. For the research purposes, a systematic network of experimental circles within the distance of 1 x 1 km was installed in the managed forest. On the intersection of the squares network, 14 circular surfaces of 25 m radius were installed. All circular surfaces were placed in different sections. In the virgin forest a permanent experimental surface of size 100 x 100 m was set, with surface of 1 ha and one circular surface of radius 25 m, with surface of 1963 m2. The research determined the horizontal (opposing) and vertical structure, the diversity, the quality of the resources and the health of the virgin forest plus the managed forest. The texture was determined only for the virgin forest. The diversity of the tree types over the number of trunks in the virgin forest is 1,79, in the managed forest 1,78, over the basal; these indexes for the virgin forest are 1,24 and for the managed forest 1,64. The virgin forest has a poorer structure of tree resources compared to the managed forest, but is of better health. In the managed forest there are many trunks of suspicious health, as much as 35,8 %. The texture diversity in the virgin forest is 2,43.
