In this article I discuss problems and possibilities connected with commissioned archaeology in wetlands. The cultural heritage of wetlands is threatened by large-scale infrastructure projects, and there is a need within commissioned archaeology to develop approaches and techniques for systematic surveying in wetlands. With examples from an on-going project in southern Sweden, different surveying techniques are presented together with some results and interpretations. Attempts to grasp the complexity of the wetlands right from the beginning of the project proved to be fruitful, in that the palaeoenvironmental interpretations were decisive for the selection of sites for trial excavations. Interpretation of peatland expansion through time was important for the reading of the landscape and the search for settlement sites. Some techniques for trial excavations in waterlogged peat are also presented.
