Sustainable forestry, which is practised in all the Nordic countries, has for many decades already guaranteed reasonable forest utilisation as regards wood raw material.
Finland’s spruce forests reach maturity at an age of between 80 and 100 years. By the end of this period, called the rotation, spruce boles have reached a diameter of some 30 centimetres at breast height, which means that the annual rings formed in the wood are only about three millimetres wide. This means close-grained, high-quality wood raw material.
The stock of spruce in Finland’s forests is close to 700 million cubic metres. Annually, some 35,000 hectares of forestland are regenerated by planting an average of 2,000 plants per hectare. A corresponding area of spruce forest is obtained through natural regeneration, meaning that Nature sows the seeds.
