More wood - decreasing increment

According to calculations from the National Forest Inventory, the total growing stock in Norwegian forests is now 842 million cubic metres. The increment decreased slightly for the fifth year in a row.

Out of the total growing stock, 763 million cubic metres stand on productive forest area. The annual increment in productive forest amounted to 22.8 million cubic metres, while the annual increment in total was almost 24.6 million cubic metres. During the last five years the annual increment has reduced by one million cubic metres.

Spruce most common

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 five years, the spruce stock has increased by 12 per cent, pine by 10 per cent and broad-leaved by 27 per cent. In total, the growing stock has increased by 100 million cubic metres in five years, even though some of the growth is caused by including areas above the coniferous forest line.

More productive forest

The productive forest area, which from the inventory cycle 2005-2009 also includes areas above the coniferous forest line, is estimated at 80 003 square kilometres. The northern county of Finnmark is not included. Neither are protected or other closed-off areas of productive forest.
