Abstract

Results of entomological survey of beetles (Coleopt era) from the Borek u Domaoova Natural Reserve (Jeseniky Protected Landascape Area): implications for conservation biology. Cas. Slez. Muz. Opava (A), 61: 197-211. A b s t r a c t : This paper is focused on the fauna of bee tles from the Borek u Domaoova Nature Reserve (NR) in the Hrub˝ Jesenik Mountains. Altogether 257 species of beetles belonging to 45 families were recorded during an entomological survey in 2011 and 2012. We found out valuable assemblages of beetles, especially a community of saproxylic be etles which is of high bioindicative value. Recorded were boreo-montane or relict species of na tural old-growth forests such as Ceruchus chrysomelinus , Curimus erichsoni, Danosoma fasciata , Dendrophagus crenatus , Elateroides flabellicornis , Hylis foveicollis , Melandrya barbata etc. We propose the following management measures, necessary for the preservation of populat ions of the threatened species of the Borek u Domaoova NR. A non-action strategy seems to be the most appropriate management by means of avoiding the removal of fallen and dead trees from the forest. On the contrary, the structure of the forest should be enriched with fir seedlings, plant ed and protected from the damage caused by deer. We also recommend to enlarging the area of the NR in the near future.
