Function: Growing stock increment

Estimated annual increment of wood has risen for many decades. In recent years it has been more than 100 million cubic meters annually. Total round wood removals have also risen on average despite their annual fluctuations but the increase has not been as rapid as that of the increment. In the 2000s forests have grown approximately 30% more in volume annually than the amount of wood removed from the forest as a result of roundwood removals and natural drain.

Most of the increase in the annual volume growth has been achieved through the draining of wooded mires, more intensive forest management as well as the fact that more forest stands now belong to the fastest growing young (30 to 60 year old) age classes.
