The paper describes the results of pollen and macrofossil analyses of the fossil lake sediments at Niechorze. Five macrofossil zones and eight local pollen zones are distinguished and the vegetational succession is described, starting with the shrub tundra dominated by Betula nana, Salix spp. and Hippophae , through the different of birch woodland and birch-pine woodland development, to the revertence of partially open plant communities with Betula nana and Empetrum . The 4 radiocarbon dates from the base of organogenic sediment place its origin at the decline of Older Dryas chronozone. The upper part of sediments represent the shortened and discontinuous Holocene sequence.
