Slovenia was hit by a catastrophic ice storm in February 2014. We analyzed the damage on forest trees due to the ice storm in the district of the Oselica Forest District (The Sovodenj forest management unit in Kranj forestry region). Damages of trees were assessed on 83 sampling plots; trees were classified into ten classes, depending on the type and degree of damage on trees. 61% of all trees were damaged, 10 % of trees must be felled because of the high degree of damage. Most trees have a damaged crown (26 %), 3 % of trees are fractured, 4.5 % of trees are uprooted. Small-sized diameter trees with diameter at breast height up to 30 cm were most severely damaged. The degree of damage is higher in deciduous than conifers. There are differences in the type and degree of damage between the tree species (spruce, fir, red pine and beech).
