Dead wood is an indicator of forest biodiversity, forming key habitats for many species. In this study they were compared the quantities of dead wood from 4 sample plots from managed forest and 4 from virgin forest from beech stands in Semenic Mountains. Analyzing the two types of forests revealed differences in the amount of dead wood. Therefore, in the sample plots from the virgin forest the mean quantity of fallen dead wood was 54.46 m3 ha-1, while in the managed forest the mean quantity was much lower: 11.32 m3 ha-1. Regarding the standing dead wood, the mean quantity in the virgin forest was 28.05 m3 ha-1, while in the managed forest the quantity was much lower: 11.38 m3 ha-1. As regards the distribution by decomposition classes, the absence of dead wood in a few classes was observed, in both types of forests. The largest proportion of standing dead wood in the sample plots from 1200 m altitude was in the second decomposition class in both forest types, while in the sample plots at 1350 m altitude it was in the third decomposition class both in the virgin and managed forest. In the case of the fallen dead wood, the largest proportion in the sample plots of 1350 m altitude was in the fourth decomposition class for both forest types, while at 1200 m altitude was in the second class for the managed forest and the third and fourth class for the virgin forest. The diversity of dead wood regarding the three categories of elements studied indicates, in general, higher values for the vrgin forest.
