Management of dead trees, principally in Sloveniaćs private forests, is nonoriented. Thus, adequate living conditions for many plant and animal species, which need their peculiar habitats, are not provided. For the purposeof the Master of Science Thesis, the quantity and structure of the coarse woody debris (CWD) among private unmanaged forest areas (strata) and managed forest areas (strata) were compared in two chosen fitogeographic regions of Slovenia. Moreover, data on the dead trees from permanent sample plots at the level of three forest management units and two forest management areas, where the strata were chosen, were analysed. Statistically significant differences in the quantity and structure of the CWD in unmanaged strata and managed strata were found. The most CWD are in the forest area of the Mura River, namely 99.3 m3/ha. In three of the chosen residual unmanaged strata, the values range between 17.5 and 29.72 m3/ha. In all three managed strata thelevel of the CWD is low, on average 2.75 m3/ha, moreover, their structure is unfavourable. The differences in the quantity and structure of the CWD among unmanaged strata can be explained by different phases of standsć development, tree structure, and microclimatic conditions. Whereas the differences between the managed and unmanaged strata occur due to the managementćs intensity. In the Forest Management Units Ravensko, Eastern Goričko and Tuhinj-Motnik, the amount of dead trees is on average between 4.09and 9.29 m3/ha. In the Forest Management Area Murska Sobota, the average quantity of dead trees is 4.91 m3/ha, calculated from data of permanent sampleplots, while the average amount of dead trees in the area of Ljubljana is 22.37 m3/ha. The management regime should be formed so as to provide diversification of the CWD in terms of quantity, size, degradation stages, distribution and tree species.
