Křížová ( 2001) found 146 species of spiders approximately 1.5 km away from this region, in Libochovka Valley, during an arachnological survey in 1999 to 2000. Spiders have never been studied within the area of the Pláně NM to date, only several findings from this region are known. Additionally, a botanical inventory was conducted ( Tichý 2016). Several zoological inventories that were carried out in the study area focused on the following taxa: Orthoptera, Man-todea, Heteroptera, Hymenoptera, Coleoptera, Lepidoptera, Diptera, Reptilia, Aves and Mammalia ( Nenadál 1994). For this reason, this research focuses on the Pláně Nature Monument (NM), an abandoned pasture with xeric grasslands in a south and south-eastern orientation. Thus, faunistic investigations in these habitats can provide important data useful for evaluation of the biodiversity state in the current landscape. In the recent cultivated landscape, grasslands have a significant role in maintaining biodiversity by providing important habitats and refuges for many species ( Duelli 1997). Lower demand for forage and poor-quality hay are the reasons why traditional grazing and mowing are no longer sustainable ( Valkó et al. Pastures are transformed into a large blocks of fields for crop production or abandonment ( Stoate et al. Since the middle of 20th century, intensification of agriculture, together with an abandonment of less productive lands, has been the major threat to invertebrates in Europe ( Tscharntke et al. The existence of species of conservation value should be taken into account during habitat management processing ( Marc et al. Thus, spiders play an important role in practical nature conservation. At a community level, spiders are able to respond quickly and distinctly to short or sudden changes in the environment and some species reliably indicate the state of that environment ( Buchar 1983, Samu et al. Suggestions regarding the management of the area are given to improve the conditions for a high and valuable biodiversity.ĭifferences in spider communities can be found even in small-scale patches within a given habitat ( Samu et al. Ten species ( Dysdera moravica, Megalepthyphantes pseudocollinus, Trichoncus affinis, Porrhomma errans, Alopecosa striatipes, Cheiracanthium oncognathum, Civizelotes pygmaeus, Zelotes aeneus, Thanatus arenarius, Talavera aperta) are discussed in details and their records in the Czech Republic are mapped. Several findings represent the northernmost occurrences of rare thermophilic spiders in the Czech Republic. However, the studied area does not belong to this particular region. 36 mainly xerothermic species were recorded, representing a valuable arachnofauna typical for the Pannonian Region. Numerous threatened species listed in the Red List of the Czech spiders were found (CR – 1, EN – 1, VU – 11, LC – 23). In total, 11634 individuals from 154 species in 88 genera from 25 families were recorded. The spiders were samdoi: 10.30963/aramit5812 pled using pitfall traps and through sweeping of the herb vegetation.
