Three phytocoenological relevés were carried out, all trees ?5 cm diameter at breast height (d.b.h.) were measured by full callipering, tree growth was analysed for sample trees, regeneration of tree species was registered on 63 sampling plots. In addition, historical data from past forest inventories werestudied. In the period from 1952 to 2003, the share of silver fir has decreased from 86% to 26%, the share of Norway spruce increased significantly,whereas the share of beech and sycamore has slightly increased. The current growing stock amounts to 350 m3 ha-1, with large-size diameter trees (d.b.h. ?50 cm) representing 51% of total growing stock. The site is divided into 16 stand patches with significant differences in tree species composition and diameter distribution. Regeneration is sufficient with silver fir prevailing in total number of seedlings (42%). 23% of all seedlings are damaged as a result of game browsingGranata (GGE Logatec, odd. 22) je raziskovalni objekt za študij prebiralnega gozda na rastišču Omphalodo-Fagetum. V objektu so bili opravljeni fitocenološki popisi, sestoje smo izmerili s polno izmero, analizirali smo priraščanje dreves in pomlajevanje drevesnih vrst. Na podlagi zgodovinskih virov smo analizirali razvoj gozdnih sestojev v obdobju 1952-2003. V tem času se je delež jelke v sestojih zmanjšal s 86 % na 26 %, znatno se je povečal delež smreke, opazen je tudi delež bukve in gorskega javorja. Lesna zaloga je 350 m3 ha-1, delež debelega drevja (d.b.h. ? 50 cm) predstavlja 51 % celotne zaloge. Objekt je razdeljen na 16 sestojev, med njimi so opazne razlike v drevesni sestavi in debelinski zgradbi. Pomlajevanje je ustrezno, v pomladku prevladuje jelka (42 %), 23 % vseh mladic v pomladku je poškodovanih zaradi objedanja divjadiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Biotehniška fakulteta
