The relation between the different microhabitats and habitats and the quantitative distribution of macroinvertebrates was investigated as well as the applicability of different sampling devices. Data processing took place by means of multivariate analysis (Flexclus, Canoco). It was concluded that the spatial-physical structure is more important to macroinvertebrates than the plant species. In fact, this spatial physical structure can be indicated as the 'mesh size' of a (micro-)habitat. In order from open vegetation, shore/dense vegetation, artificial substrate, bottom material, and filamentous algae the 'mesh size' decresed. It is advisable to use different sampling devices to sample a macroinvertebrate community.
