During summer 2011, severe outbreak of the Spruce Bark Beetle (Ips typographus) occurred in the Šumava National Park (NP). We aim to elucidate the laws governing population dynamics of this species and conclude that logging of all infested trees in the NP buffer zones, accompanied by a non-intervention policy in the core zones, is a strategy that will protect both, forests surrounding the NP and the most valuable mountain spruce stands in the Šumava NP. and Pavel Kindlmann, Karel Matějka, Petr Doležal.
