In 2006 a hurricane blew down 125 ha of mostly mature even-aged spruce stands on the Jelovica plateau. Two post-windthrow inventories of regeneration were executed two and five years after the windthrow. Presence, abundance and composition of natural regeneration were surveyed on 81 plots of 16 m2 each. The proportion of plots without natural regeneration decreased from 30 % in 2008 to 11 % in 2011. The average abundance of regeneration was 7,955 individuals per hectare in 2008 and 9,660 individuals per hectare in 2011. In tree species composition spruce predominated with 46 %, but the proportion of broad leaves increased substantially in the observation period. Additionally, the impact of site and stand factors on regeneration was examined; influential factors of natural regeneration occurrence were investigated using a binary logistic regression, while influential factors of changes in regeneration density were examined using a generalized linear regression model. Among many influential factors, the analyses exposed the distance to the nearest stand, aspect/sun exposure, and the portion of leaf-litter on a plot.
