Abstract
Rastlinojeda divjad predstavlja na nekaterih območjih velik problem zaradi prekomernega in ponavljajočega objedanja mladja, kar zavira ali celo onemogoča njegov razvoj. Vzrokov za to je lahko več, ne samo preštevilna divjad, ampak tudi pomanjkanje primernih prehranskih virov, povečanje nemira v habitatih divjadi, neugodno stanje gozdov itd. V pričujočem delu je predstavljeno stanje v Območni enoti (OE) Celje. Podatki o objedenosti so bili pridobljeni od Zavoda za gozdove Slovenije (ZGS), ki so jih zbrali po prenovljeni metodi v letih 2009 in 2010. V nalogi je prikazana objedenost in tekoča letna objedenost po višinskih razredih in drevesnih vrstah. Največja objedenost je bila ugotovljena pri mehkih in plemenitih listavcih. Pri prvih v višinskem razredu od 30 do 60 cm, kjer je znašala 45 %, in pri drugih v višinskem razredu od 60 do 100 cm, kjer je znašala 66 %. Pri iglavcih je največji delež objedenosti pri borih v višinskem razredu od 15 do 30 cm, znaša 50 %. Veliki rastlinojedi v OE Celje zaenkrat ne predstavljajo velike težave. Večje poškodbe se pojavljajo samo lokalno. Trend divjadi je sicer naraščajoč, ni pa bilo ugotovljene previsoke številčnosti. Večjo težavo predstavlja premajhen delež mladovij (pomanjkanje prehranskih virov in kritja)oz. porušeno razmerje razvojnih faz.

Abstract:
Herbivorous game represents a major problem in some areas due to excessive and repeated damage it causes to saplings, which slows down or even prevents their growth. There are several possible reasons for this, not only excessive number of game but also lack of adequate food sources, increased disorder in game habitats, unfavourable condition of forests, etc. This thesis presents the situation in the Regional Unit of Celje. Data on the damage were obtained from the Slovenian Forest Service (SFS), which collected them by a revised method in the years 2009 and 2010. The paper shows damage and current annual damage according to height classes and tree species. The largest damage was observed in soft and in noble deciduous trees. In the first, in the height class between 30 cm and 60 cm, the damage was 45 %, and in the latter, in the height class between 60 cm and 100 cm, the damage was 66 %. Among coniferous trees, the largest percentage of damage is in pine trees in the height class between 15 cm and 30 cm, and amounts to 50 %. Large herbivores in the RegionalUnit of Celje do not represent a major problem for now, and major damage occurs only locally. While the trend of game is increasing, it has not been established that numbers are too high; a greater problem lies in an insufficient proportion of shoots (lack of food supplies and protection) or in a disrupted ratio of developmental phases.
