Carbon Husbandry

Forest Carbon number and Forest Carbon flux can be calculated at regional level similarly as at National level. In Finland the current (2020) available regional data of National Forest Inventories (NFI), however, is restricted only to two latest NFIs, for the periods 2009-2013, (central year 2011) and 2014-2018 (central year 2016). The regional data restriction is merely due to 1994 administrative decision to redefine the borders of Finnish regions in a new manner. After the reform the amount of Finnish regions is 19 . Let us take as example for calculations the region Pohjois-Pohjanmaa - North Ostrobothnia . By geography it is in central Finland. The amount of solid cubic meters  in North Ostrobothnia forests was 240 million cubic meters in 2011 and 263 million cubic meters in 2016. Correspondingly, the area of forest hectares was 3.244 million hectares and 3.235 million hectares in 2011 and 2016, respectively (NFI 11 and NFI 12 inventories). With average Carbon Multiplier ...

The definition of Forestry land in Finland is based on the volume growth of existing, living trees in the selected area - or on the potential volume growth in same area if there has been for instance a temporary forest clear cut in the area. In the standard silviculture the area is waiting for replanting or for natural recovery, in a few (less than 10) years. The Forestry land has been divided into four categories (Figure 1). First, when the average volume growth (stems only) is more than one solid cubic meter per hectare per annum, the land area is called Forest land. Second, when the average volume growth is between 0.1 - 1.0 m3/ha/a the land area is called Poorly productive forest land. Third, when the average growth is less than 0.1 m3/ha/a the land area is still included in the main category of forestry land but it has been nominated as Unproductive (forest) land. Fourth, under the main Forestry category there is still a minimal forestry land class called Forest roads and depots....
