    Presented are the results of the analysis of botanical macroremains, pollen, mol, luscs, mammals, fish and a number of other remains from a deposit in the lower Scheldt basin north-west of Antwerp (Belgium). On the basis of these remains we can reconstruct the flora and fauna of this area during the late Atlantic. Tens of liters of a sandy basal layer of a gully-filling were sieved. A 1 piece of wood from this layer is radiocarbon dated 5750 ± 40 BP. Fifty meter from the gully a peat layer was sampled. The base has been dated to 6020 ± 70 BP and the top to 4630 ± 60 BP. This means that the gully was active during part of the formation of the peat. This peat is found in many places in the area and developed from halfway the Atlantic to halfway the Sub-Atlantic. Pollen analysis points to a deciduous forest during the Atlantic and Sub-Boreal. Alnus is the dominating species. The non-arboreal pollen amount to 10-30 % of all counted pollen, except water- and sporeplants. Evidently Alnus grows along the gully in wet forests, and in the somewhat higher places (riverbanks, riverdunes, borders of the valley) Quercus, Corylus, Tilia and Ulmus were present. In zones IV and V the percentage of Chenopodiaceae and Poaceae is high (marine influence?) and in zone VI sporeplants increase strongly. In the top part of layer 6 many plant and animal remains were present. Remarkable were large amounts of fruits and cones of AInus glutinosa. Nuphar lutea and Ranunculus (aquaticus-type) must have been present in the water. On higher places many shrubs and trees like Quercus robur and Tilia platyphyllos were growing. The deposit was also very rich in molluscs (86 species). We found species from a variety of freshwater habitats: from running to stagnant water, small pools, periodically dry waterbodies, etc. Mercuria confusa is an animal which is characteristic for the freshwater tidal area. Some species are very rare in Holocene deposits (and in the modern fauna) of this part of Europe. An example is a big pearl mussel Pseudanodonta auricularia. The same can be said for the remains of landmolluscs: they represent many habitats and interesting species. We found, e.g., Lauria cylindrica, Clausiliidae, Vertigo spp, Acanthinula aculeata, Helicigona lapicida. They lived in marshy places, moist to dry places with herbs and shrubs, and moist to dry deciduous forests. Other groups and species found are noted in chapter 9. All remains point to an area with a great variety of habitats in the valley of the River Scheldt. A gully with fresh water was influenced by the tides. Different types of waterbodies with stagnant water were present. Brooklets drained into the gully. Alder carr occured in the lower wet places. On the transition to higher grounds many shrubs were growing, and on the higher grounds themselves a deciduous forest was present.
