In this study, we present faunistic data about spiders in selected sinkholes of northern part of Moravský kras Protected Landscape Area. Time of collection was established in the following terms: 24 March 2010 – 22 September 2010. We collected altogether 5742 adult specimens which were determined to 59 species of 14 families. We found two very rare spiders (critically endangered Porrhomma errans and endangered Walckenaeria monoceros) and several interesting, rarely collected bioindicator species (Alopecosa trabalis, Mecopisthes silus, Zelotes longipes). From the bioindicative evaluation point of view, 44% of found species belong to species with connection to natural habitats, 37% belong to species preferring semi-natural habitats, and 19% belong to species of disturbed habitats. From the relictness point of view, majority of species was of the expansive category (53%), 40% of class II relicts, and only 7% of class I relicts. Sink holes did not increase total biodiversity of agricultural land too much because of their relative small size.
