1 Logging residues form a substantial portion of the dead wood in managed forests, and logging residues can facilitate bark beetle multiplication and outbreaks. For these reasons, it is highly advisable to find a way of reducing the risk of bark beetle outbreaks without extensive removal of logging residues, which is inconsistent with nature conservation. 2 The coverage of Pityogenes chalcographus (L.) galleries and the presence of other bark beetle species on 3520 fragments of logging residues of the Scots pine ( Pinus sylvestris L.) that originated over different months from 2004 to 2008 were examined in 135 stands in four study areas of the Czech Republic. 3 Pityogenes chalcographus was the most abundant species. 4 The month of felling had a significant effect on the coverage of P. chalcographus galleries on logging residues. 5 Concentrating felling in August and September (and possibly October) can minimize the risk of P. chalcographus multiplication and outbreaks.
