The second dry shift can be \nrelated to local peat exploitation of the mire. In the 20th century \nadditional limited drainage took place and since ca. AD 1950 the mire \nhas been recovering. From 1500 AD onwards all proxies indicate wetter \ncondition. The beginning of this wet shift occurred during the Little \nIce Age and may therefore be a climatic signal. The macrofossil data \nshow that Sphagnum fuscum dominated the pristine mire vegetation but \nthen declined and finally disappeared at ca. AD 1900. This pattern is \ncomparable with the timing of extinction of Sphagnum austinii \n(= Sphagnum imbricatum) in the UK. This study illustrates the value \nof high-resolution multi-proxy studies of peat archives to assess \nthe magnitude of anthropogenic land-use changes. This study presents \nthe first direct comparison of testate amoebae and stable isotope \ndata from the same core. The two proxies correlate significantly \nthroughout the record and most strongly for the latter part of the \nrecord when most of the variability was recorded. \n\n","author":null,"citation":"Lamentowicz, M., A.
