Spinnen van zeven Nederlandse stuifzandgebieden

From 2006 to 2009 the Dutch Ministry of Agriculture, Nature and Food Quality financed a research project on inland drift sands. The main goal of the project was to detect bottlenecks for characteristic geomorphological processes, plant and animal species in order to increase restoration and conservation efficiency for these special ecosystems. This article focuses on the spider fauna of these drift sand areas. In 2007/2008 an inventory of the fauna was made by means of pitfall traps for seven drift sand areas in the Netherlands in the provinces of Friesland, Drenthe, Overijssel, Gelderland, Noord-Brabant and Limburg. Exact locations and habitat descriptions of the traps as well as dates on which pitfall traps were opened and dates they were emptied are presented. A list of all species of spiders found in these drift sand areas is provided. New species for the different Dutch provinces are marked with ‘*’. The species Cheiracanthium montanum L. Koch, 1878 (2 females on Kootwijkerzand) is new for the Dutch fauna.
