    Knowledge on requirements of dry-grassland inhabitants is vital to slow down decline of grassland biodiversity. We studied habitat requirements of eight flightless steppe beetles, including some of the most endangered dry-grassland specialists of the continent. The beetles were sampled using 167 pitfall traps at a pannonian dry-grassland fragment, the Pouzdrany steppe, SE Czech Republic. Two of the studied species required relatively humid microhabitats, including tallgrass steppe with litter (Carabus hungaricus, Carabidae) and grassland of high herb cover (Meloe proscarabaeus, Meloidae). Others were associated with xeric habitats (e.g. Meloe scabriusculus) and their early-successional stages, including short-turf vegetation (Dorcadion fulvum, D. pedestre, Cerambycidae) and/or bare-ground patches (Blaps lethifera, Tenebrionidae; Meloe decorus, M. uralensis). Spatially and temporarily highly diversified patch management creating a fine scale mosaic of various seral stages from bare soil to tall-grass steppe is therefore the most appropriate approach for managing isolated grasslands. Prescribed burning and support of burrowing herbivores are recommended and discussed together with other measures for restoration of habitat diversity in dry-grassland fragments.
