Slovenian forests are over-mature, the current ratio of forest development phases is unfavourable, forest regeneration is too slow, or the areas of forests under restoration are too small to significantly change the share of forest development phases and thus ensure sustainable forest development. The role of forests as a carbon sink is at risk.

Net greenhouse gas (GHG) emissions in the land use, land-use change, and forestry (LULUCF) sector amounted to -3.106 kt CO₂ eq in 2021. In this year, the net emissions were higher or sinks smaller by 1.2% compared to the previous year and by 57% compared to 2005. According to data from the Slovenian Forest Service, felling in 2021 decreased by only 3.6% compared to 2020. In 2021, and for the first time since 2014, the share of sanitary felling was less than a third of the total annual felling.

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.

Areas of fields and gardens in measures that require fertilization based on rapid soil or plant tests have significantly exceeded the target value set by the 2014–2020 Rural Development Programme.

In the period after 2000, nitrogen consumption from mineral fertilisers initially declined. After 2009, consumption more or less stabilised at around 27,500 tonnes, with annual values ranging from 26,300 to 29,143 tonnes. With the exception of 2021, the target value (< 28,000 t) has been achieved in recent years. The increase in 2021 was probably the result of purchases of mineral fertilizers for stock, which were made due to expected price increases and supply disruptions.
