Growing stock volume continues to increase
According to calculations by the National Forest Inventory, the total growing stock in Norwegian forests is now 823 million cubic metres. During the last 10 years, the stock has increased by 125 million cubic metres.
For the first time, forest areas above the coniferous forest line are included in the total growing stock.
Out of the total growing stock, 749 million cubic metres stand on the productive forest area. The annual increment in productive forest amounted to 23.1 million cubic metres, while the annual increment in total was almost 24.8 million cubic metres. The increment decreased slightly for the fourth year in a row.
More broad-leaved
Spruce is the most common species of tree with 44 per cent of growing stock, followed by pine with 32 per cent and broad-leaved with 25 per cent. During the last 10 years, the spruce stock has increased by 17 per cent, pine by 11 per cent and broad-leaved by 30 per cent. In total, the growing stock has increased by 125 million cubic metres in 10 years, even though some of the growth is caused by including the areas above the coniferous forest line.
More productive forest
The total area of wooded land is calculated to be 123 840 square kilometres. The productive forest area, which from the inventory cycle 2005-2009 also includes areas above the coniferous forest line, is estimated at 79 963 square kilometres. The northern county of Finnmark is not included. Neither are protected or other closed-off areas of productive forest.
