This issue of Metla’s Working Papers is based on the Finnish COST Action FP 0707 Expected Climate Change and Options for European Silviculture (ECHOES) country report published in 2009 compiled with updated information. The main goal was to review the state-of-the-art of climate change issues related to Finland’s forests.

The main effects of expected climate change in Finland’s boreal vegetation zone are: The growing season in the northern coniferous zone is likely to lengthen; forest growth may increase; wind damage will become more prevalent; and in the temperate zone insect pests are expected to spread northwards, possible causing damage on a massive scale. A consequence of climate change could be a northwards shift in the tree-line zone and the gradual extinction of certain species in forests in tree-line areas in the northern polar region.

Good and timely forest management is the main way of improving the ability of forests to adapt to climate change. In forest regeneration, depending on stand conditions, both natural regeneration as well as planting and seeding with improved genetic breeding material are recommended. Safeguarding environmental conditions on the site by wooden biomass extraction need more attention and research, while the soil nutrient loss and water protection have been considered as environmental threats by the increased extraction of wooden biomass. Awareness of the importance of forest management in adapting to climate change must be increased among members of the public, forest owners and those responsible for forest management.

In Finland strong emphasis has been put on the mitigation issues by promoting the use of wood. These actions include the increased use of wood-based bioenergy (including biofuels) and wooden construction. In the land use, land-use change and forestry (LULUCF) sector Finland has a sink of carbon that amounted to -35 million tons of CO2 during 2008. That sink originated mainly from a sink in the tree biomass, which is driven by the amount of annual fellings – i.e. the sink is greater when annual fellings are less.
