Oct 12, 2009. /Lesprom Network/. This year's national forest inventory made by the Swedish University of Agricultural Sciences shows that the part of deciduous trees in Swedish forests is now the biggest since the 1920s, The Nordic Forest Owners' Association reported. The country's timber resources are still increasing. Deciduous trees have increased most, like in previous years. They constitute almost one fifth of the country's total timber resources, i.e. about 600 million cubic metres. At present deciduous trees are economically more advantageous than before. The reason is an increased environment consciousness. The University points out that also the severe storm damage that hit spruce forests in Southern Sweden has contributed to a more favourable attitude to deciduous forests. Aggregate annual growth is still strong and now amounts to 121 million cubic metres. The damage done by the two storms Gudrun in 2005 and Per in 2007 is still visible in Southern Sweden. In this region growth is still somewhat weaker and timber resources are smaller. Since the start of national forest inventories in the 1920s timber resources in Sweden have almost doubled. Spruce is still the dominant species, but pine is increasing more strongly and its volume is almost the same as spruce, i.e. about 1.3 billion cubic metres.
