Spinnen (Araneae) en hooiwagens (Opiliones) van Boswachterij Staphorst

In this contribution we present the 50 spider and 14 harvestman species that were found during an inventory of the nature reserve “Boswachterij Staphorst”. This area is surrounded by agricultural lands and contains dry forests, heathland, and some pools. All species found were to be expected in the studied biotopes. Six spider species were not published before for the province of Overijssel. For the harvestmen, a detailed overview of abundances in pitfall trap series in six biotopes (dark birch forest, open spruce forest, dry heath, sod-cut area, wet heath, edge of agricultural meadow) is presented.
