In 2016, the artificial forest regeneration area totalled 109,000 hectares, showing an increase of six per cent from the year before. Private forests made up 80,000 hectares. The area treated with fellings, based on notifications of forest use, was 653,000 hectares, showing an increase of seven per cent from the year before. Notifications of forest use regarding private forests were made for 452,000 hectares.
Of the artificial forest regeneration area, 83,000 hectares were cultivated by planting and 26,000 hectares by seeding. The proportion between planting and seeding remained unchanged from the previous year.
Forest seeding is mainly done mechanically. In the 2000s, the proportion of mechanical seeding has increased from 50 per cent to the current level of 80 per cent.
– However, planting is almost always a manual process, as the proportion of mechanical planting was only one per cent, says senior statistician Aarre Peltola from Natural Resources Institute Finland (Luke).
Of the forest planting area, 63 per cent was allocated to spruce and 32 per cent to pine. Other planted tree species, birch mainly, accounted for five per cent. The proportion of pine planting increased from the year before. When seeding, pine is nearly always the tree species used.
The area treated with fellings, based on notifications of forest use, totalled 653,000 hectares in 2016. Clearcutting is estimated to total 141,000 hectares and natural regeneration roughly 27,000 hectares. In private forests, the harvesting area was 452,000 hectares, with clearcutting making up 100,000 hectares.
The area of pre-commercial thinnings totalled 147,000 hectares
– The total area of pre-commercial thinning and early pre-commercial thinning stands was 147,000 hectares in 2016, Peltola says.
This shows an increase of four per cent from the year before. Pre-commercial thinnings are carried out both manually and mechanically, even though the use of mechanized methods has not yet increased. The proportion of mechanical methods was two per cent.
The improvement of young stands covered 47,000 hectares, showing an increase of 17 per cent from the previous year.
Total costs of silviculture and forest improvement were EUR 251 million
– Of these total costs, EUR 195 million were allocated to private forests and EUR 56 million to forests owned by companies and the state, says researcher Ville Kankaanhuhta.
Of different work types, pre-commercial thinnings generated the highest costs, i.e. EUR 59 million, while EUR 51 million was invested in artificial regeneration of forests . Soil preparation consumed EUR 34 million and improvement of young stands required EUR 19 million. Of the total costs, forest road and ditch improvement accounted for EUR 42 million.
