Abstract
Po žledolomu februarja 2014, ki je zelo prizadel gozdove na Notranjskem in osrednji Sloveniji, je sledila neustavljiva gradacija smrekovih podlubnikov. V revirju Planina so bili popolnoma uničeni vsi smrekovi nasadi in vsi sestoji z velikim deležem smreke. Tako so nastale velike ogolele površine, zato bo v bližnji prihodnosti potrebna načrtna obnova teh gozdov. V revirju Planina smo v poškodovanih smrekovih nasadih na rastišču Omphalodo-Fagetum typicum izpeljali retrospektivno študijo uspešnosti preteklih sanacij po ujmah v letih 2006%2008. Popisali smo 75 ploskev na posajenih površinah in 75 ploskev na neposajenih površinah. Na posajenih površinah rezultati nakazujejo višjo kakovost mladja in ugodnejšo drevesno sestavo, najpomembnejši pa je drugi višinski razred mladja, medtem ko na neposajenih prevladuje prvi. Razlike v skupnih gostotah na posajenih in neposajenih površinah so bile mejne. Pri tem je potrebno upoštevati, da so bile naravni obnovi prepuščene površine z ugodnejšimi razmerami za naravno obnovo.

Title:Assessment of post-disturbance restoration of forest areas in Planina forest district
Abstract:
Ice damage in February 2014 has generated high-scale damage on broad forest areas in Notranjska and in Central Slovenia. The ice damage was followed by an unstoppable gradation of Norway spruce bark beetles. Most of the spruce monocultures and forests with a higher share of spruce in forest district Planina were totally destroyed. This resulted in large-scale forest openings, where only bare soil remained. Within the near future, systematic restoration of post-disturbance areas will be needed. In the Planina forest district, a retrospective survey was carried out on an Omphalodo-Fagetum typicum site to assess the efficiency of past (2006-2008) post-disturbance restoration efforts. We inventoried 75 plots in planted areas and 75 plots in unplanted areas. In the planted areas, results indicate a higher quality of seedlings and a better tree composition. In these areas the most important group was the 130-250 cm tall trees. In the unplanted areas, the group of 50-130 cm tall trees had the highest density. Nevertheless, the overall differences in density values were small. However, it must be taken into account that the areas left to natural succession had better starting conditions for natural regeneration.
