The soil fauna of the “Mantingerveld” in the province of Drenthe was inventorized between July 2001 and August 2003. The inventory was carried out with pitfall traps. The results for the fauna of spiders, harvestman and pseudoscorpions are presented here. A full report of the inventory was presented in June 2005 to Natuurmonumenten and also includes centipedes, millipedes, isopods and earwigs. The results are compared with some other large scale inventories in the Netherlands.
