Two dots (..) mean that value is missing Values for unproductive forest land have been adjusted to the values that SLU presents for each year in its official statistics. Statistics Sweden´s statistics report the same values as SLU for the years 2018–2021. Statistics Sweden´s values for the years 2022 and 2023 refer to SLU´s statistics for the year 2021, as later reference years are missing in SLU´s statistics. The same values are presented for the last three years, to obtain comparable values with the other three forms in the statistics. Values for consideration patches and voluntary set-asides have been revised continuously due to continuous quality increase in method and input data. In conjunction with the publication of the 2023 statistics, values for voluntary set-asides 2020, 2021 and 2022 have been revised, as well as values for consideration patches 2018, 2019, 2020, 2021 and 2022. The proportion in percent has been calculated using non-rounded values in hectares. In the calculation, the numerator consists of the areas of the selected variables. The denominator consists of the area of forest land according to the official statistics on forest land in Sweden in the Swedish National Forest Inventory with regard to the forms Voluntary set-asides, Consideration patches, and Unproductive forest land. In the calculation of the proportion of Formally protected forest land, the denominator consists of the area of forest land according to the Swedish data on land cover mapping (NMD). Since the NMD is the source for the area in the numerator, that is, formal protection area, the quality of the statistics are considered to be enhanced if the same source is used for both the numerator and the denominator.

Overlapping forms

Areas that overlap other forms have been eliminated. The fact that the four different forms overlap means that several forms may exist within the same area. In the statistics, overlaps only exist between formally protected forest land and unproductive forest land. Formal protection is presented in its entirety. Unproductive forest land without overlap has been reduced from areas that are also formally protected.

Forest land

Productive forest land refers to forest land that is considered to be able to produce on average at least one cubic metre of wood per hectare and year.

Forms

Formally protected forest land

Formally protected forest land is a collective term for different forms of protection, determined by laws, ordinances, agreements and individual decisions. Formal protection contains major overlaps between various subsets. In the statistics, these overlaps have been excluded in order to present a net area of formally protected forest land. This form exists in both productive and unproductive forest land.

Voluntary set-asides

Voluntary set-asides refers to areas of productive forest land on which landowners voluntarily decided not to carry out any measures that can harm natural values, cultural environments, or social values. Values are not available for the regions in/below the subalpine region, as well as for Swedish geographical regions.

Consideration patches

Consideration patches refers to small areas of productive forest land that have been made available, voluntarily or pursuant to the Swedish Forest Care Act, for rejuvenation harvesting. Values are not available for the regions in/below the subalpine region, Swedish geographical regions, and counties.

Consideration patches

The area of consideration patches are preliminary estimates based on the most recent definitive three-year average value in 2018/2019.
