The European spruce bark beetle Ips typographus (L.) is one of the most important pests of mature Norway spruce Picea abies (Karst.) in Europe. Outbreaks (periods with large-scale beetle-caused tree mortality) are often triggered by large-scale stormfellings or drought, which provide a large surplus of suitable breeding material. The overall aim of the studies in this thesis was to increase knowledge about how forest characteristics and local beetle populations influence tree mortality and bark beetle outbreak dynamics in time and space. We found that the size of infestation spots in general were small (
