TY - JOUR N2 - We present the last millennium of history of a peatland located in northern Poland. Our results are based on two replicate monoliths taken from a Baltic raised bog. We applied a high-resolution approach and radio car bon dating to the peat material to obtain a de tailed palaeoenvironmental reconstruction. To reconstruct past peatland moisture, we used three prox ies: testate amoebae, plant macrofossils and pollen. Despite different peat accumulation and extensive hiatus in the formerly studied core, both monoliths show a similar pattern of changes. However, the core from this study provides us with more detailed data on S. fuscum disappear ance which correlates well with the data from the other Baltic bog, S³owiñskie B³oto. Our re search shows that pris tine Bal tic bogs can be dated to AD 1350. Słowiñskie Błoto palaeohydrology confirms AD 1300 as the beginning of the hydrological disturbance. In the case of the Stążki and Słowiñskie Błoto bogs, the Little Ice Age (LIA) is recorded between AD 1500 and AD 1800. However, this climatic change might have been blurred by human impact. In the case of the Baltic bogs, their reference virgin state can be dated to AD 1200. After this date, we observed in creasing human impact and climatic in stability connected with the LIA. However, between AD 1800 and 1900, bogs were wet, most possibly due to climatic forcing. This fact suggests that despite human impact, recent peat deposits can still reflect climate. Our research provided in formation related to the time of existence, location and characteristics of the natural/pristine state. High-resolution peatland palaeoecology is crucial for restoration activities, e.g., rewetting and environmental management. The palaeohydrological context (supported by other proxies) of the last 1000 years provides a reliable answer to the question: ‘To rewet or not to rewet?’ L1 - http://journals.pan.pl/Content/118405/PDF-MASTER/s_03_16.pdf L2 - http://journals.pan.pl/Content/118405 PY - 2011 EP - 16 KW - Baltic bog KW - last millennium KW - multi-proxy KW - Poland KW - peatlands KW - raised bog A1 - Lamentowicz, Mariusz A1 - Gałka, Mariusz A1 - Pawlyta, Jacek A1 - Lamentowicz, Łukasz A1 - Goslar, Tomasz A1 - Miotk-Szpiganowicz, Grażyna PB - Committee for Quaternary Research PAS PB - Institute of Geological Sciences PAS VL - Vol. 28 DA - 2011 T1 - Climate change and human impact in the southern Baltic during the last millennium reconstructed from an ombrotrophic bog archive SP - 3 UR - http://journals.pan.pl/dlibra/publication/edition/118405 T2 - Studia Quaternaria ER -
