We present the first Holocene multi-proxy record from the southern Baltic raised bog. Testate amoebae, plant macrofossils and pollen were used to reconstruct palaeoenvironmental and climatic changes in Pomerania (N, Poland, Kaszuby Lakeland) from seven-metre peat archive of St??ki bog in period 5300 BC - AD 1500. Peat accumulation was not stable in time and it depended on the bog surface wetness change. BSW reconstruction is correlated with other palaeohydrological studies from Poland and Europe. Testate amoebae recorded high water table between 5500 BC and 3500 BC as well as from 500 BC. Lower water table and hydrological instability was inferred between 3500 AD and 500 AD. All proxies correspond very well reflecting climatic change since 7000 BP and they indicate particularly Subboreal and Atlantic wet conditions. Between AD 0 and AD 1500 pollen and testate amoebae compared show similarities and suggest that those two proxies were driven by allogenic factors, e.g. appearance of Fagus sylvatica and increase abundance in testate amoebae Hyalosphenia papilio and H. elegans suggest wetter conditions and change of the trophic state in the peatland ecosystem. This period is also connected with the domination of Sphagnum sec. Acutifolia. Drier conditions were inferred between 3500 and 0 BC, where also more unidentified decomposed organic matter was found. There is also a very distinctive transition between Corylus and Carpinus dated to 1700 BC to 1200 BC indicated also by other proxies -  testate amoebae Phryganella acropodia and plants – Eriophorum vaginatum. This suggests the gound water table decrease. Furthermore we observed an intriguing connection between Carpinus betulus, increased accumulation of Sphagnum sec. Acutifolia and both Hyalosphenia species that might have climatic origin. The further work on the profile and comparisons with other investigated sites are expected to reveal regional climatic pattern in Pomerania.
