Abstract
Piotrkowo site is located in the western part of the Dobrzyn Plateau. Detailed pollen analysis of the Piotrkowo I core enabled a reconstruction of environmental conditions change over last several thousand years. The results indicated three different stages of the organic sedimentation, two limnic and one terrestrial. The first stage of Plenivistulian age lake is recorded in organic silt sediment, partly laminated. The second stage contains traces of Holocene age lake preserved in carbonate gyttja sediment. The last phase includes a record of dynamic changes in the groundwater level recorded in terrestrial sediments - highly decomposed peat and organic loam.
