A faunistic study of bark beetles species occurring at Mt. Smrčina/Hochficht in the southern part of the Bohemian Forest was carried out in 2009, two years after the Kyrill hurricane. The study area was located on the border between the Šumava NP in the Czech Republic and private forests in Austria. The management policy is non-intervention in the core zone of the Šumava NP, whereas commercial forest management is applied on the Austrian side of the border. The original survey focusing on the migration of the bark beetles (primarily Ips typographus) in the border area recorded high number of different species and offered opportunity to study also the species diversity. This study presents its faunistic results. Species diversity was studied along three transects. There were five monitoring sites along each transect. At each site traps were arranged in the form of two crosses in which there was one pheromone trap (‘active trap’) and nine traps without pheromone (‘passive trap’). Of the total of 150 traps set in the study area only fifteen were baited with pheromone. Eighteen species belonging to the family Scolytinae were caught by the traps during the five months of this study. Five of the species feed only on spruce, eleven are polyphagous feeding on Picea spp., Pinus spp., Abies alba, and Larix decidua. In addition, there were two species, Scolytus intricatus and Xyloterus domesticus, which probably feed on old maples growing in historically grazed parts of the forest. Ips typographus, Pityogenes chalcographus, Dryocoetes autographus, and Dryocoetes hectographus were the most common species. The first two species dominated the catches of the traps baited with pheromone. Several rare species, including Pityogenes conjunctus, were also caught. Species diversity and ecology of recorded bark beetles species are discussed to support current debates about more appropriate management of the forests in the National Park.
