Being part of a zoological monitoring program, the purpose of this work was the evaluation of the spider fauna of restored sites at the Upper Drau River in Carinthia. Seven of these restoration sites and two natural reference sites were sampled, both by qualitative hand-collecting and quantitative sampling with wooden frames of fixed size. The results were compared to given data obtained in the years 2003 (ÖKOTEAM) and 2006 (BRANDL). In total, 80 species out of 17 families were identified, with 41 % of them being classified as endangered species. The work primarily focused on unvegetated gravel bars. Additionally, a more detailed mapping and transect-based sampling of Kleblach, the largest restoration site, was carried out. Particular attention was paid to ripicolous lycosid spiders, where the obtained data indicates that at least 5 of originally 7 species of this guild were able to settle. Also notable is the evidence of the critically endangered lycosid spider Arctosa cinerea. However, the habitat offered by the recreated restoration sites is temporary limited: As a consequence of missing floodplains, a shifting of the gravel bars does not take place. This results in soil solidification, rapid vegetation encroachment and further rapid and big loss of unvegetated gravel bars and sandy beaches - together with their ripicolous spider communities. The total current spider density at the Upper Drau is just one fourth of the density stated in the year 2003; especially older succession areas show very low densities. Opposed to that, at younger restoration sites a very high density up to 164 individuals per square meter can be reported. The present data shows a negative correlation between the age of the restoration site and the amount of ripicolous species. New restoration measures should be developed to promote river dynamics and a more nature-orientated condition.
