Megjegyzések:	Agricultural intensification threatens grasslands worldwideand the restoration of grasslands from arable lands canat least partially counter this threat. We studied grasslandrestoration by following early successional changesof arthropod assemblages (spiders, Araneae; true bugs,Heteroptera; orthopterans, Orthoptera; and ground beetles,arable lands and native grasslands as two ends of thesuccession timescale. To examine the changes in speciescomposition among the habitat types, we used habitat affinityindices based on fidelity and/or specificity of the species.We found that the number of species did not differ betweenhabitat types, while species composition changed markedlywith time. Species richness was thus not adequate todetect favorable changes after grassland restoration. Habitataffinity indices, on the other hand, were useful to detectcompositional changes caused by the increasing numbersof species characteristic of target grasslands as early asthe second year after restoration. Habitat affinity indicesare easy-to-use, easy-to-interpret measures of restorationsuccess; therefore, we recommend their use as measurescomplementary to species richness and simple similarity.Our results show that sowing low-diversity seed mixturefollowed by mowing and grazing can be particularly successfulin grassland restoration in time periods as short as2 years.
