The studied locality, i.e. Klánovický les Forest is situated on the edge of Prague, one of the most polluted areas in the Czech Republic. Thanks to large area the forest acts as an isolation from agrochemicals, thus allowing the existence of some habitats sensitive to eutrophisation, in particular peat-bogs, heaths, bare sandy soils, and Molinia meadows. The habitats harbour unusually high species diversity of spiders and
harvestmen: the author recorded 286 spider and 11 harvestman species there, which is approximately one third of the Czech fauna. Sixty one of them are red-listed in the Czech Republic. Peat-bog linyphiid Saaristoa abnormis, and steppe lycosid Alopecosa schmidti and linyphiid Panamomops inconspicuus are listed as endangered. Local small peat-bogs offer suitable conditions for disappearing lycosids Hygrolycosa
rubrofasciata, Pirata piscatorius and Piratula uliginosa, while heaths harbour the disappearing Oxyopes ramosus. Water spider Argyroneta aquatica has recently been found in small pools in ditches along the railway. Littoral vegetation is inhabited by Theridiosoma gemmosum and the jumping spider Calositticus floricola. Disturbed soil surface of wet meadows harbours the wolf spider Arctosa leopardus. Some species have recently appeared at the site, for example Dysdera hungarica, the harvestman Nemastoma bidentatum sparsum or the crab spider Synema globosum. The first two were probably introduced there by man, the latter probably expands due to climate change. The author suggests to keep these habitats without woody vegetation to protect local high species diversity there.

Results of the exploration of the araneofauna and the entomofauna in West Bohemian heathlands are presented. Spiders and carabid beetles were collected during the vegetation seasons in 2011 and 2012 by the method of pitfall trapping. In total, 3188 specimens of 171 Araneae species and 2168 specimens of 93 Carabid species were determined. The most frequent spiders were Xerolycosa nemoralis (Westring, 1861), a common forest species. The following identified species are listed among the endangered spiders in the Czech Republic in the category „endangered“: Alopecosa schmidti (Hahn, 1835), Micaria dives (Lucas, 1846),  Peponocranium orbiculatum (O. P.-Cambridge, 1882), in the category „vulnerable“: Centromerus incilium (L. Koch, 1881), Evansia merens O. P.-Cambridge, 1900, Metopobactrus prominulus (O. P.-Cambridge, 1872), Arctosa figurata (Simon, 1876), Arctosa lutetiana (Simon, 1876), Pardosa nigriceps (Thorell, 1872), Gnaphosa bicolor (Hahn, 1833), Xysticus striatipes L. Koch, 1870, Evarcha laetabunda (C. L. Koch, 1846) and Trichopterna cito (Blackwall, 1841). The most remarkable species of the Carabids were the Amara equestris equestris (Duftschmid, 1812), Amara pulpani Kult, 1949, Bradycellus ruficollis (Stephens, 1828), Carabus arcensis arcensis Herbst, 1784, Carabus problematicus harcyniae Sturm, 1815, Cymindis axillaris axillaris (Fabricius, 1794), Cymindis vaporariorum (Linné, 1758), Masoreus wetterhallii wetterhallii (Gyllenhal, 1813), Olisthopus rotundatus rotundatus (Paykull, 1790). Studied material was reposited at the Department of Zoology of the West Bohemian Museum in Pilsen.
