Risikovurdering av Ips amitinus ved tømmerimport - Sannsynlighet for introduksjon og effekt på barkbilleutbrudd

Abstract

En ny barkbilleart Ips amitinus har vært påvist i importtømmer i 2002. Vi har studert muligheten for at denne arten kan bidra til hyppigere eller forsterkete barkbilleutbrudd i samspill med granbarkbillen. Undersøkelsen har benyttet modellsimuleringer, siden eksperimenter som kan øke risikoen for nyetableering ikke er akseptabelt. Simuleringene viser at denne nye arten under visse betingelser kan bidra til økt forekomst og intensitet av barkbilleutbrudd. Et føre var prinsipp tilsier at en bør søke å unngå at I. amitinus etableres i norske skoger. Funn av overvintrende individer av den nye arten på lagerplasser for importtømmer, samt innledende resultater fra en trinnvis importmodell, indikerer en stor risiko for at Ips amitinus kan spre seg og etablere seg i norsk skog. De innledende modellresultatene viser imidlertid også at det finnes mulige virkemidler for å dempe risikoen.
