Najveći procenat površina sa neuspelim pošumljavanjima nalazi se na najvećim nagibima i na toplim ekspozicijama. Površine pod vitalnim kulturama nalaze se na severnim ekspozicijama i u uvalama. Mezofilniji uslovi, nastali promenom mikroreljefa uticali su na bolji prijem, veću vitalnost sadnica, a samim tim i veću stabilnost kultura. In the region of the mountain massif Suvobor, we analysed the effect of exposure. and slope on the degree of endangerness of Austrian pine plantations, aged 15 years, total area 1378.63 ha. The highest percentage of areas with unsuccessful afforestation occurs at the steepest slopes and on warm exposures. The area with vital plantaticns are situated on north exposures and in valleys. More mesophilic conditions, resulting from the changed micro-relief, caused better survival, greater seedling vitality, and also a greater stability of plantations. https://unilib.phaidrabg.rs/o:7124 ISSN: 0351-9147 UTICAJ EKSPOZICIJE I NAGIBA TERENA NA STEPEN UGROŽENOSTI KULTURA CRNOG BORA (Pinus nigra Arn.)
