Quaternary sediments in the river Swieder floodplain (Central Poland, about 75 km SE from Warsaw) are represented, too, by sediments suitable for pollen analysis, which are organic sediments of palaeomeanders. In the course of 2004 the international interdisciplinary research started at 2 localities: Seroczyna (SER) and Stoczek tukowski (STO). Seroczyna (SER): Following identified plants (e. g. Salix, Ulmus, Tilia, Fraxinus, Alnus, Cyperaceae, Poaceae) characterize the typical floodplain vegetation. Human influence is proved by anthropogenic plants (e. g. Cerealia, Artemisia, Plantago, Centaurea cyanus, Agrostemma githago, Rumex, Fagopyrum, Urtica, Brassicaceae, Chenopodiaceae, Sambucus nigra). Stoczek tukowski (STO): Following identified trees (e. g. Salix, Populus, Alnus, Ulmus, Tilia, Fraxinus, Acer), some bushes (e. g. Viburnum, Hedera) and herbs (e. g. Cyperaceae, Poaceae) characterize the typical floodplain vegetation. Human activity is demonstrated by anthropogenic plants (e. g. Artemisia, Plantago, Centaurea cyanus, Rumex, Cerealia, Asteraceae, Chenopodiaceae, Brassicaceae). The development of vegetation of both palaeomeanders, as shown by the pollen analyses, can be preliminary classified to the Subboreal period and mainly to Subatlantic (Firbas 1949, 1952). Palynological study will continue in the years to come.
