English Summary
Spiders in Tofte Skov, Denmark
To date, 311 species of spiders, 57% of the known Danish fauna,
have been recorded from Tofte Skov, a protected area in Northern
Jutland encompassing the largest intact raised peat bog in northwestern
part of Europe (app. 2000 ha.), as well as large areas of
deer and wild boar grazed old woodlands, heath, inland sand dunes,
meadows, and conifer plantation. Spider sampling was carried out in
all seasons 2003 to 2010. Fourty species not previously known from
Northern Jutland were recorded and ten are listed on the Danish
Red List. Araneus alsine is listed as endangered, while Araneus marmoreus,
Dolomedes plantarius, Heliophanus dampfi and Hygrolycosa
rubrofasciata are vulnerable and Alopecosa inquilina, Dolomedes fimbriatus,
Enoplognatha thoracica, Pardosa sphagnicola and Taranucnus
setosus are near-threatened. Six of the Red List species are associated
with peat bog habitat and edge vegetation along the peat bog, while
four are found in the dry habitats. A number of rarely collected species
were also found: Philodromus longipalpis and P. praedatus (open
woodlands with old trees) and P. albidus (woodlands with old trees,
hedges and solitary trees), Xysticus luctator (beech forest), Sitticus
saltator (inland sand dunes), Evansia merens and Gnaphosa nigerrima
(wetter areas with Sphagnum cuspidatum in raised bogs), Notioscopus
sarcinatus and Walckenaeria nodosa (peat bog) and Styloctector stativus
(humid meadows). The large number of spiders recorded can
be explained by the diversity of habitat types in Tofte Skov and the
persistence of these habitats since the iron-age.
