Abstract	Representative sampling of ant communities is time-consuming and laborious. Due to their manifold habitat requirements and sociobiological attributes, a suite of sampling methods is necessary to detect nearly all ant species in a given habitat. We analysed how well different combinations and intensities of sampling methods are suited to assess ant species richness and community patterns. Sampling occurred at 24 sites in mountain and floodplain habitats in Austria using pitfall traps, Winkler litter extraction, hand sampling of foragers, and colony sampling. Of these, pitfall traps delivered the largest species numbers. We drew 19 subsets of sampling approaches and compared these to the complete data. Many subsets that allowed for substantial reduction of work effort nonetheless reflected well the beta diversity patterns of the whole dataset. In contrast, alpha diversity assessment was more sensitive to reduced sampling effort. Pitfall traps turned out to be indispensable to collect ant species for biodiversity studies, but the optimal combination of sampling methods varied between habitat types. In rugged montane habitats pitfalls should be complemented at least by colony sampling. In floodplain forests the number of pitfall trap replicates can be reduced, but inclusion of Winkler samples is advisable.
