We examined the differences in tree felling in private forests in Ljubljana forest management region by property size. The analysis was based on Timber database of the Slovenia Forest Service for 1995-2013 period. Forest properties were divided into five size categories. We analysed the amount of felling per hectare, the number of trees cut per hectare and medium felled tree. We found significant differences in mean values of variables by size categories. The amount of felling is the greatest on the smallest property. The medium felled tree is the lowest on the smaller property and the highest on the largest. Except for the period 2001-2006, the annual felling has increased. The sharpest increase of felling was noticed after 2006 on the smallest properties. Owners of smaller properties cut higher percentage of available cut. The same applies to the number of trees cut. The results can be used in formatting stimulations for greater cutting.
