The health status of forests in Slovenia has been relatively stable in recent years, but with a slight negative trend. In 2014 and 2015 we observed an increased defoliation, due to ice storm and wind throws, followed by a stable defoliation status in both - conifers and deciduous trees. In 2020, for the first time, the average defoliation of conifers was lower than the average defoliation of deciduous trees.

Good

Forests in Slovenia are relatively well preserved, especially in terms of the diversity of the natural tree species composition and the vertical and horizontal stand structure. The share of preserved forests exceeds 50%. Heavily modified, mostly forests where natural tree species are altered with spruce, and altered forests makes up just over a tenth of all forests.

Good

In Slovenia, forests have been growing in terms of growing stock and increment for decades. They have increased by more than 140% over the last 70 years. In addition to natural conditions, harvesting depends on socioeconomic factors, and recently on the occurrence of natural disasters (windbreaks, icebreakers) and bark beetles outbreaks. By 2014, the felling accounted for about 50% of the increment. After the ice storm in 2014, it increased substantially and represented 60 to 75% of the total increment of conifers and deciduous trees.

Good

In the past centuries, forest area has been increasing constantly after 2010; however, the rate of expansion has slowed down and remains relatively stable in recent years. Since 1875, when forests covered only 36 % of the Slovenian territory, forest cover has increased to 58.5 % in the year 2009 and rests stable today at 58,0 %. In terms of forest share, Slovenia ranks third among EU-28 countries, behind Sweden and Finland.

Neutral

Regarding the forest area, deforestation accounts for an insignificant share. The average of the last ten years is approximately 405 ha (between 350 – 550 ha per year) and thus does not represent a significant factor in forest cover changes. Until 2008, most deforestation is a result of infrastructure facilities construction..

Good

Deadwood is an important animal and plant habitat that contributes to the biodiversity of forest ecosystems. According to Slovenia Forest Service data, the volume of standing and fallen trees without stumps and branches in 20119 was 19.6 m3/ha, which represented approximately 6% of the entire wood stock of forest stands. In virgin forests, however, the deadwood volume can be even several dozen times larger.
