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 as regards the "annual change of stands in regeneration" was neutral in the period 2010–2016, went down in 2016, and then increased steeply and reached the peak in 2018 and then declined again. The average share of artificial regeneration in the period 2010–2021 represented 9.3% of all restoration.
