Šteta zbog guljenja kore koju nanosi jelen (Cervus elaphus L.) u ograđenom uzgajalištu 'Lomnička Reka'

Abstract

Šteta zbog guljenja kore je ozbiljan problem u nekim šumskim lovištima Srbije. Cilj istraživanja je bio da se utvrdi opseg i intenzitet guljenja kore koje uzrokuje jelenska divljač u ograđenom uzgajalištu 'Lomnička reka' (planina Veliki Jastrebac, centralna Srbija). Podaci su kolektirani detaljnim pregledom celog uzgajališta u proleće i jesen 2008., 2009. i 2010. godine. Ovi rezultati pokazuju da jelenska divljač u proleće i leto isključivo guli koru lišćarskih vrsta drveća, uglavnom bukve (86,3% ili 536 stabala) i graba (10,1% ili 63 stabla). Opseg i intenzitet guljenja kore su najveći u debljinskoj klasi od 20-39,9 cm. Oštećena stabla su utvrđena u svim delovima uzgajališta, na svim ekspozicijama i različitom nagibu terena. Kora bukve je guljena u periodu maj-avgust, sa težištem guljenja u junu ili julu.

Bark stripping damage is a serious problem in some forest hunting grounds in Serbia. This study aimed at assessing the incidence and intensity of bark stripping by red deer in the fenced rearing centre 'Lomnička Reka' (Mt. Veliki Jastrebac, central Serbia). The data were collected by detailed surveying of the entire rearing centre over spring and autumn 2008, 2009 and 2010. Our results show that, in spring and summer, it is exclusively broadleaf tree species that are bark stripped by red deer, mainly beech (86.3% or 536 trees) and hornbeam (10.1% or 63 trees). The incidence and intensity of bark stripping were the highest in the diameter class of 20-39.9 cm. Damaged trees were identified in all parts of the rearing centre, at all aspects and at different slopes. Beech bark was stripped over the period May-August, with the focus in June or July.
