%X A beetle inventory using window traps was performed to examine the  effect of forest restoration by artificial addition of dead wood on the  abundance of beetles and to evaluate the risk of bark beetle damage in a  forest restoration area. The number of beetle families was slightly  increased, but no consistent differences were found in the abundance of  families containing saproxylic Coleoptera between the restoration and  control plots. The abundance and species number of bark beetles and  longhorn beetles were significantly higher on the restoration plots. Ips  typographus and Pityogenes chalcographus increased only slightly in  abundance. In the regression models produced, the abundance of bark  beetles was best explained by the volume of recently dead wood. However,  the bark beetle species whose abundance increased most were secondary  and the material also suggests an increase in the abundance of bark  beetles’ natural enemies. The risk of bark beetle damage in the area is  thus considered insignificant.
