About the statistics

The information under «About the statistics» was last updated 5 June 2023.

Growing stock

Total volume of the standing forest under bark. Comprises trees with a diamter of at least 5 cm at breast height (1.3 metre above ground level).

Annual increment, forest

Annual gross increment in volume in standing forest inside bark.

Development class

Describes the forest's development class from non- regenerated forest to old forest.

Site quality

An expression of the area's capacity to produce wood when stocked with a tree species suitable for the local growing conditions. The site quality of the H40-system is based upon the top height (the average height of the hundred trees per hectare with the largest diameter) of the trees at the age of 40 years at breast height (1.3 m above ground level).
