The presented article contains the results of macroscopic analysis of plant remains (fruit, seeds and wood), deposited on the site of the Tarnobrzeg group of the Lusatian culture in Grabowiec, site 1/50/105-85 AZP, commune Radymno. All the discussed pieces remained in a burnt condition. They represented few residues of Einkorn wheat cereals Triticum monococcum, spelt Triticum spelta and proso millet Panicum miliaceum. In the group of wild herbal species there was recorded the presence of plants related today with arable fields (Bromus secalinus, Thlaspi arvense and Galium spurium) or field and ruderal habitats (Chenopodium album). The most strongly represented were the remains of trees and shrubs. On their basis Carpinus betulus, Fraxinus excelsior, Pinus sylvestris, Acer, Alnus, Betula, Quercus and Ulmus were marked. The composition of the anthracologic spectrum suggests that in the neighbourhood of the site forests in the type of today’s broadleaved forest developed (oak, hornbeam involving maple and lime) and riparian forests (ash and alder).

Ślady późnoglacjalnej i holoceńskiej historii doliny Neru są dobrze zachowane w osadach paleokoryta Kolonia Bechcice (NKB), które zostało odcięte w młodszym dryasie. Jego rozwój może być podzielony na pięć wyraźnych faz. Podczas młodszego dryasu NKB było dość głębokim, oligotroficznym jeziorem. Z nastaniem holocenu starorzecze uległo eutorfizacji i zarosło roślinnością wodną, a następnie szybko przekształciło się w torfowisko niskie. Brak jest w profi lu NKB osadów ze środkowego holocenu. Torfy z okresu borealnego przykryte są przez mułki i piaski pozakorytowe zdeponowane w okresie subatlantyckim. Zapis ewolucji paleokoryta Kolonia Bechcice dowodzi, że dolina Neru była dynamicznym środowiskiem w późnym glacjale i holocenie. Ekosystemy starorzecza podlegały znacznie silniej presji zmian klimatycznych niż jeziora i mokradła znajdujące się na wysoczyznach w regionie łódzkim.

The history of the Ner River valley is well documented in Kolonia Bechcice (NKB) palaeochannel sediments. It was cut-off from the riverbed in the Younger Dryas. Its history may be divided into five distinct phases. During the Younger Dryas, the NKB was a relatively deep, oligotrophic water body. From the onset of the Holocene, the lake became a eutrophic, overgrown pond which quickly palludified and transformed into a rich fen with ferns and birches. There is a hiatus in the middle of the Holocene fen stratigraphy. A peat sequence is covered by fluvial silt and sand deposits. The NKB sequence documents the Ner valley as a dynamic system during the Late Glacial and the Holocene. Local ecosystems of this oxbow have remained under a much stronger pressure of climate changes than palaeolakes and wetlands located on uplands in the Łódź region.
