Příspěvek k poznání brouků (Coleoptera) Významného krajinného prvku Placy – Černé bláto

Abstrakt: The small-scale protected area Placy – Černé bláto near Příbram (Central Bohemia) was established in 2008 to preserve large populations of the Marsh Gentian (Gentiana pneumonanthe) and the Alcon Large Blue butterfly (Maculinea alcon alcon Denis et Schiffermüller, 1775). The protected area comprises about 2.9 ha, and is a part of a larger complex of wet meadows surrounded by large forests. The meadows were historically used for production of charcoal. In the second half of the 20th Century, the meadows were used as a military shooting training area. Since the 1990s, the meadows have been abandoned and were partly afforested. This situation changed with a change of ownership in 2012; the new owner deforested the area, began mosaic mowing of the meadows, and intended to renew the sport shooting area. This study summarizes the results of a survey of the beetle fauna of the locality, conducted occasionally since 1981. In total, we have confirmed 250 species of beetles of 33 genera, based on 321 records. Another fifteen species are known only from historical data. The range of species corresponds to the common fauna of wet, and also partly dry, meadows. A significant proportion of the fauna is associated with pine forests and forest edges.
