Secondary succession of vegetation and soil mesofauna was followed for several years in 3 replicate experiments on artificially created synchronous successional and recultivated (grass) sites in 1980, 1982 and 1985. The data presented cover a period of 2 years, with special reference to the Gamasina (Acari). There is evidence that the grass vegetation has a positive influence on the development of soil mesofauna, which is mainly caused by the specific microclimate. Other indirect effects are discussed. In an ecotoxicological experiment, the succession of the "twin sites" under uncontaminated conditions was compared with that under the influence of 2.5 g m-2 Aldicarb (single application). Different reactions of the soil mesofauna were observed on the two synchronous sites (undisturbed succession and grass).
