Last millennium palaeoenvironmental changes from a Baltic bog (Poland)
inferred from stable isotopes, pollen, plant macrofossils and testate
amoebae.

The Baltic coast of Northern Poland is an interesting region for
palaeoclimatic studies because of the mixed oceanic and continental
climatic influences and the fact that the dominance of one or the
other of these two influences might have changed over time.
Also, unlike many more intensively studied regions of Europe,
human impact in the region was rather limited until the 19th century.
We present a 1200-year high-resolution record from Stazki mire,
an ombrotrophic bog located 35 km from the Baltic Sea coast.
Using testate amoebae, stable isotopes (d13C) of Sphagnum stems,
pollen, plant macrofossils and dendroecological analyses, our aims
were to: 1) reconstruct the last millennium palaeoenvironment
in the study site and its surroundings, 2) identify the major
wet-dry shifts, 3) determine if those events correlate with climate
change and human impact, 4) assess the resilience of the Baltic bog
ecosystem following human impact, and 5) compare the palaeo-moisture
signal from the Baltic coast with records from more oceanic regions.
Two dry periods are inferred at AD 1100-1500 and 1650-1900 (-2005).
The first dry shift is probably climate-driven as pollen record shows
little evidence of human indicators. The second dry shift can be
related to local peat exploitation of the mire. In the 20th century
additional limited drainage took place and since ca. AD 1950 the mire
has been recovering. From 1500 AD onwards all proxies indicate wetter
condition. The beginning of this wet shift occurred during the Little
Ice Age and may therefore be a climatic signal. The macrofossil data
show that Sphagnum fuscum dominated the pristine mire vegetation but
then declined and finally disappeared at ca. AD 1900. This pattern is
comparable with the timing of extinction of Sphagnum austinii
(= Sphagnum imbricatum) in the UK. This study illustrates the value
of high-resolution multi-proxy studies of peat archives to assess
the magnitude of anthropogenic land-use changes. This study presents
the first direct comparison of testate amoebae and stable isotope
data from the same core. The two proxies correlate significantly
throughout the record and most strongly for the latter part of the
record when most of the variability was recorded.
STUDY NOTES: Depth to Water Table (DWT) reconstruction for Stazki Bog, Poland
based on Testate Amoeba. Two time series are included. SL1 is the
published data (Lamentowicz et al., 2008a). This peat core has
a 400 years hiatus. Also provided is data from peat core SL2,
which is continuous and not disturbed, but unpublished. It was
analysed with the same methods as peat core SL1.
The study site is a Baltic bog located in northern Poland,
ca 35 km from the Baltic sea coast, in the Kaszuby Lakeland,
near the highest point (214.6 m a.s.l.) of a moraine plateau.
All calculations are based on percentage of each species of
Testate Amoeba in a sample (See Booth et al., 2010).
Age model is from (Lamentowicz et al., 2008a).
Depth to Water Table (DWT) is dependent on vegetation season
temperature and summer water deficit, providing a mixed
temperature and precipitation signal.

of Lamentowicz et al., 2008b.
