The collection process preserved nearly all animals alive, including the most fragile and small ones. Therefore live sorting or dead sorting of the material could be done. Spiders, for instance, were gained out from a sample most easily by simple live sorting on a tray. If several or very numerous taxa were necessary to be extracted from the sample, they needed to be killed after collection and sorted afterwards. Field study design The field study was carried out on an adjacent meadow and alfalfa field at Nagykovácsi (Juliannamajor), at the north-west border of Budapest. Suction samples and sweep net samples were taken on 7 July 1994, whereas pitfall traps were opened one week preceding this date and emptied on the 15 July. The height of the alfalfa was c. 40 cm with 20% of the plants in flower. In the meadow the vegetation was 50-70 cm.
