Mass outbreaks and factors related to the spatial dynamics of spruce bark beetle (Ips typographus) dieback considering diverse management regimes in the Białowieża forest

•Dynamics of spruce stand mortality varied across the study area.•Presence of trees other than spruce in stands reduces the risk of tree mortality.•Spruce height influence significantly mortality dynamics.•The most intensive outbreak progressed in old stands dominated by spruce.•Mixed young forests or pine stands were the most outbreak-resistant areas.
