Postglacial occurrence and decline of Betula nana L. (dwarf birch) in northeastern Poland
The Late Glacial and Holocene presence of Betula nana L. (dwarf birch) in northeastern Poland was reconstructed through palaeoecological analyses of sediment cores from the Taboły mire located in the territory of the Knyszyńska Forest. Peat records spanning thousands of years were analysed for plant...

The Late Glacial and Holocene presence of Betula nana L.

Peat records spanning thousands of years were analysed for plant macrofossils along with radiocarbon dating. Betula nana was present in Taboły from ca 13 000 to ca 9000 yr BP. The presence of this species was described in the Late Glacial period, most likely in the Allerød and Younger Dryas. However, our research on the palaeoecology of dwarf birch showed that after the Late Glacial/Holocene transition, the species did not disappear from northeastern Poland and still existed in the Preboreal, Boreal and lower Atlantic periods.
