Spider communities on intensively managed agricultural grasslands were sampled using pitfall traps. The factors affecting the distribution of communities were investigated using two-way indicator species analysis, canonical correspondence analysis and discriminant analysis. The major factors affecting the communities were altitude and pasture utilisation strategy. The main effects of altitude appeared to be related to the greater surrounding areas of unmanaged grasslands in upland, which provided a larger pool of colonising species. Management practices, such as silage production, appeared to have an influence on lowland grassland communities.
