The volume of growing stock indicates the opportunities available
for the use of wood and harvesting. The volume of growing
stock is the basic input figure for several forestry planning
calculations, as it is a close approximation of the total biomass
in forests, forming the basis for instance for calculating carbon
sequestration.
In 2010, the growing stock volume was 2,284 million solid
cubic metres over bark (Fig. 1.2). The figure includes trees on
low productive forest lands (56 million cubic metres) as well
as trees on lands outside regular wood production3 (208 million
cubic metres).
The total volume of growing stock in Finnish forests has increased
since the 1960s. This is due to the creation of new productive
forest land by drainage and by afforestation of agricultural
land, increased growth, a decrease in the number of lowyield
stands, changes in the age structure of forests, and above
all the fact that the increment has exceeded harvesting drain.
3 In the NFIs, this category includes conservation areas based on the Nature
Conservation Act and on other legislation, natural forests, recreation forests,
park forests, recreational areas for short-range outdoor activities, training areas
of the Defence Forces and other special areas where clear cuttings and other
silvicultural measures are restricted.
