  1. 1. Granbarkborre (Ips typographus) och Skyddad skog : Orsakar skyddad natur granbarkborreangrepp i produktionsskog?

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Gustav Eriksson; [2021]
    Nyckelord :European spruce bark beetle; Ips typographus; protected forests; forest pest;

    Sammanfattning :   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. LÄS MER
