Spruce bark beetle

Last changed: 20 June 2016

An increase attacks on growing forest by spruce bark beetle (Ips typographus) was seen after the severe storms in 2005 and 2007. A large number of wind felled spruce trees were left in the forest, and the population of spruce bark beetle rapidly increased. A risk of escalating damage to the forests was foreseen.

TFDIs have been carried out in southern Sweden in autumn 2007 and in one county in northern Sweden autumn 2011.  The inventories showed large but not escalating damage. The inventory in northern Sweden also indicated a large number of spruce trees killed by the small spruce bark beetle (Polygraphus poligraphus).
