Solid cubic meters of forest trees and their annual growth in Finland since 1921
At national level the most remarkable above ground Carbon stock in Finland is in the forests. The most common basic measurement for the forests, is the amount of above ground solid cubic meters in the trees. It is normally measured for the stems only. The data correlates strongly with the total dry biomass in the trees (stems, branches, foliage, stumps and roots). Further, the solid cubic meters data correlates strongly with the amount of elementary Carbon in the trees (stems, branches, foliage, stumps and roots). Photo 1. Boreal forests are a remarkable Carbon stock in Finland. The changes in the amount of solid cubic meters in the trees indicate the changes in the Carbon stock. Positive change tells about the Carbon sink flux into the forests. Negative change tells about the Carbon source flux (or Carbon emissions flux) from the forests. The regular inventory of forest trees, for their solid cubic meters, has been done in Finland since 1921 (Figure 1). The latest National Forest I
