Abstract

The study focuses on facts about the role of the forests, near the mountains in the northwestern part of Sweden, from a climate perspective. This refers to the net removal in living tree biomass while the substitution effect is omitted. The area-based (design based) estimates are based on data from the Swedish National Forest Inventories permanent sample plots in two areas close to the mountains. The first area refers to the above limit for forests close to the mountains (above GFS) according to the Swedish Forest Agency and the second according to a map layer that is considered important of protection for biodiversity reasons according to the Swedish Environmental Protection Agency (SEPA). Of the 8.1 Mha of land above the limit for forests close to mountains, 3.1 Mha is forest land, of which 1.7 Mha is formally protected forest land. Productive forest land used for timber production amounts to less than 0.5 Mha. For both formally protected forest land and non-formally protected forest land, living biomass constitutes a net uptake of -1 Mton CO2 / year during the period 1990-2016 on a reasonably similar area. If all forest land above GFS is excluded from timber production, the short-term increase in net removal in the forest will be approximately -0.4 Mton CO2 / year, which corresponds to harvest. Then we do not expect any substitution effect and believe that other carbon pools (dead wood, soil, litter and the carbon pool harvested wood products) in the short term are not affected by the stopping of felling. The Swedish Environmental Protection Agency has selected an area close to the mountains where two thirds comprise forest land. No land is formally protected. Of approximately 1.0 Mha of forest land, 0.39 Mha was assessed as forest land for timber production. The net uptake in living biomass of forest land amounted to approximately -1 Mton CO2 / year during the period. On productive forest land for timber production, the net uptake was approximately -0.6 Mton CO2 / year during the period. If all forest land according to the map layer is excluded from timber production, the short-term increase in net removal in the forest will be approximately -0.1 Mton CO2 / year, which corresponds to harvest. Then we do not expect any substitution effect and believe that other carbon pools in the short term are not affected by the stopping of felling.The study focuses on facts about the role of the forests, near the mountains in the northwestern part of Sweden, from a climate perspective.
