Beavers have lived in the territory of Poland since the beginning of the Holocene, as testified by bone remains found in archaeological sites of different ages. The area inhabited by these animals has experienced continuing transformations of terrain relief, geological structure, hydrology and plant cover. In Poland, beavers are partially protected and their population has spread in virtually every part of the country (except in the highest mountain ranges). The authors of this paper wish to present the results of field works carried out since 2006 in the Tuchola Forest (Polish Plain). This paper aims to identify the potential sediments of relict beaver ponds and their sedimentological features. The studies are also backed up with a description of radiocarbon dating of samples. The results indicate that beavers used to live in the Tuchola Forest in the Middle Ages, as shown by the radiocarbon dates and sequences of mineral–organic deposits found in exposures and geological boreholes. The spatial distribution of organic and mineral deposits in wider sections of river valleys can be explained by the avulsion of the riverbed downstream of the pond and by the distribution of ponds in the Gołyjonka valley. The discovery of relict beaver pond sediments suggests that the activity of these mammals in the Middle Ages played a major part in shaping the landscape of the valley. The results of studies clearly indicate that analyses of the valley sediment facies of small watercourses should take into account the role beavers played in the past in shaping the landscape of the analysed valley. This highlights the insufficiency of studies concerning the activity of beavers in river valleys.

“…The radiocarbon dating was performed applying a liquid scintillation technique (LSC method) and using alpha/beta spectrometers: Quantulus 1220 and ICELS (Pawlyta et al, 1998;Tudyka and Pazdur, 2010;Tudyka et al, 2015). Calibration of radiocarbon dates was carried out using the computer calibration program OxCal 4.2 (Bronk Ramsey et al, 2010) based on the calibration curve IntCal13 (Reimer et al, 2013).…”

Abstract:The paper presents the results of the latest radiocarbon dating and the palynological analyses of organic sediments found in the alluvia of the Wisłok River valley between the towns of Łańcut and Przeworsk. The study conducted in the gravel pit made possible the dating of several alluvial fills of the 7-8 m high Holocene terrace and the 5-6 m high floodplain. The oldest channel alluvia and palaeochannel sediments of the 7-8 m high terrace were dated at 10 100-9300 BP (11 960-10 500 cal BP). According to the anthracological analysis the top cover of clay overbank alluvia, which bears charcoal fragments, was deposited in the Subboreal and/or the Subatlantic Phases. In the sequence of the 5-6 m high floodplain, the bottom fills of palaeochannels, dated at 10 195-9885 cal BP (probability level: 68.2%; GdS-3233: 8900 ± 95 BP ) and 11 095-10 755 cal BP (probability level: 68.2%; GdS-3228: 9575 ± 95 BP), were truncated by erosion and covered by alluvia of palaeomeanders, which were active in the 19 th century. Preservation of the erosional bench of the Early Holocene organic sediments indicates the predomination of lateral migration of the river channel during the last 200 years and the formation of wide erosional floodplain that has been aggraded with recent flood alluvia. In the 20 th century the floodplain aggradation was simultaneous with the deepening of the Wisłok riverbed.
