Methods

This is a study on primary succession. In both subareas two sets of two pitfall traps (5 m separated) were operational from July 1969 until October 2008. The traps consisted of a 15 cm wide plastic funnel provided with a small plastic bottle containing a 4% formalin solution. The funnel was placed in a dug-in metal container flush with the ground level. A perspex roof secured by a brick prevented flooding of the funnel by rain. Catches were initially gathered each week, later on, when the functioning of the traps was less disturbed by blown sand and debris, as a rule each fortnight. Trapping was discontinued in late October and started again in late March. Due to an epidemic of foot-and-mouth disease in 2001, access to both the Sennerplaat and the Schildhoek was denied, hence the gap in the tables and the graphs. The catches were gathered, sorted and identified to species level by the first author. Initially only carabid beetles (Coleoptera,Carabidae) and spiders (Arachnida, Araneae) were taken into account. Later, other minor groups colonized the area and also were recorded. In this way harvestmen (Arachnida: Opiliones), woodlice (Crustacea: lsopoda: Oniscoidea), myriapods (Diplopoda) and one rove beetle species (Coleoptera: Staphylinidae) were added to the list of species studied.
