News Forestry, Statistic

In Finland, forests cover three quarters of the land area. The growing stock volume on forest land and poorly productive forest land totals 2,482 million cubic metres, and the mean growing stock volume per hectare on forest land is 119 cubic metres. The latest information is based on the National Forest Inventory data measured in years 2015 – 2019. Information about increment of the growing stock and the volume of dead trees has not been updated in this publication.

The area of forestry land in Finland is 26.3 million hectares, covering 86% of the total land area. Forest land covers a little more than three quarters of forestry land. Poorly productive forest land accounts for 10% and completely or nearly treeless unproductive land 12% of forestry land. In these statistics, the total area covered by forest land and poorly productive forest land is called forests. Forestry roads and other forestry maintenance areas cover 1% of forestry land.

“Forest land covers two thirds of Finland’s land area. The coverage of forest land is the highest in Etelä-Savo, in which forest land accounts for 85% of the land area. Correspondingly, the coverage is the lowest in the Åland, 41% of the land area”, says Kari T. Korhonen, principal scientist at the Natural Resources Institute Finland (Luke).

Mineral soils make up the majority of forestry land

Peatlands account for one third of forestry land, while the rest consists of mineral soils. A little more than half of the current peatland area on forestry land has been drained. The proportion of peatlands is the lowest in the Åland where mineral soils make up 92% of forestry land. In Mainland Finland, the proportion of peatlands is the lowest in Päijät-Häme and Uusimaa, with peatlands accounting for a little more than 10% of the forestry land area in both regions. Correspondingly, the proportion is the highest in the regions of North, Central and South Ostrobothnia where the proportion of peatlands from the forestry land area ranges from 53% to 44%.

“The growing stock volume on forest land and poorly productive forest land totals 2,482 million cubic metres. Pine accounts for half, spruce 30% and deciduous trees the remaining 20%”, says senior statistician Eeva Vaahtera.

One quarter of the volume of the growing stock is in peatland forests and the rest on mineral soil forests. Two thirds of the growing stock volume are located in Southern Finland. Lapland, the region with the largest surface area, has the largest growing stock, i.e. 17% of the growing stock volume. In the regions of Southern Finland, Central Finland has the largest growing stock volume (198 million cubic metres).

A total of 90% of the volume of the growing stock is in forests available for wood supply. The forest available for wood supply does not include conservation areas, for example.

The largest mean volume in Kanta-Häme

The mean growing stock volume on forest land is 119 cubic metres per hectare. The mean volume is higher than this in Southern Finland (145 cubic metres per hectare), while it is lower than this in Northern Finland (88 cubic metres per hectare). Regarding different regions, the mean growing stock volume is the highest in Kanta-Häme (173 cubic metres per hectare) and the lowest in Lapland (76 cubic metres per hectare).

 

The annual increment of growing stock on forest land and poorly productive forest land totals 108 million cubic metres, while mean annual increment is 4.7 cubic metres per hectare. On forest land, mean annual increment is 5.2 cubic metres per hectare. Mean annual increment on forest land is the highest in Kanta-Häme (8.3 cubic metres per hectare). In Lapland, mean annual increment on forest land remains at 2.3 cubic metres per hectare.
