Carbon Husbandry

Picture 1. The forests in Kainuu region are typically coniferous forests, under practical silviculture Kainuu region is geographically a central or central-eastern region in Finland. It is forested, scarcely populated region. Forestry is an important source of livelihood in the region. The amount of solid cubic meters in 2011 in Kainuu forests was 163 million cubic meters and 172 million cubic meters in 2016. Correspondingly, the area of forest hectares was 1.930 million hectares and 1.928 million hectares in 2011 and 2016, respectively (NFI 11 and NFI 12 inventories). With average Carbon Multiplier CM = 0.35314 tn C/m3 the total Carbon stock (stems, branches, foliage, roots) in Kainuu was 57.6 million tons in 2011 and 60.7 million tons in 2016. Forest carbon number is calculated by dividing the total carbon stock (c, tn C) at certain time point (t, years) with the forest land area (fl, hectares) at certain time point, for the selected area. (1)     fc(t) = c(t) / fl...

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 ...
