The aim of this report was to investigate whether the management of protected forests cause increased risk of infestation by the European spruce bark beetle (Ips typographus) in production forests, and whether the risk of infestation in production forests is greater in the vicinity of protected forests. The survey was conducted by using GIS-data covering suspected attacks and forests that are susceptible to infestations. The proportion of infested forests in three different buffer zones located around the protected areas were compared. The results show no evidence suggesting that protected areas serve as a hatchery for spruce bark beetles and no increased risk of infestations in the vicinity of protected forests were detected.
