English title: Confirmation of the results of forest amelioration of drained peatland forestsTiivistelmä
Approximately half of the original area of Finnish peatlands, 10 Mha, have been drained for forestry. In addition slightly less than 1 Mha of paludified mineral soil have been drained. The drained area comprises approximately one quarter of the present total forest area in Finland and the current growth of tree stands on drained peatland forests is steeply increasing. Thus the increase in the annual growth increment due to forest amelioration is presently c. 8 Mm3 and increasing by several percent each year. While this trend is welcome a third of drained peatland area already needs urgent additional drainage and silviculture management if it is to continue. Keywords: Drainage, peatlands, silviculture
