Tiivistelmä

Up to the present 5 Mha of peatland, i.e. 50% of the total peatland area of Finland, have been drained for forestry. The annual growth of peatland forests has increased from 6 Mm3 in the 1920s up 15 Mm3 in the 1980s, which is 22% of the total annual growth of the country's forests. To maintain the drainage systems, about 40 000 km of ditches should be cleaned annually. Silvicultural management of tree stands on peatlands is another urgent task in the near future.
