Most Slovenian forests are still undergoing natural regeneration, which guarantees the stability of future forest stands and adaptation to the changing site conditions caused by climate change. Restoration by planting seedlings and sowing (artificial regeneration) only complements natural regeneration when disturbances occur in the process of the natural regeneration of the forest, e.g. where there is no possibility of natural seeding, with the risk of developing erosion processes on exposed forest areas (e.g. forest stands affected by natural disasters) or when we want to change the existing inadequate tree (species) composition of the forest.
The trend in the "annual change in stands in regeneration" was stable in the period 2010–2016, declined in 2016, then began to rise steeply and peaked in 2018. It declined again until 2021, followed by an increase that peaked in 2023 and a further decline in 2024. The average share of artificial regeneration in the period 2010–2024 was 15.9 % of the regeneration stands (annual change in areas).
