Summary: | The history of the Ner River valley is well documented in Kolonia Bechcice (NKB) palaeochannel sediments. It was cut-off from the riverbed in the Younger Dryas. Its history may be divided into five distinct phases. During the Younger Dryas, the NKB was a relatively deep, oligotrophic water body. From the onset of the Holocene, the lake became a eutrophic, overgrown pond which quickly palludified and transformed into a rich fen with ferns and birches. There is a hiatus in the middle of the Holocene fen stratigraphy. A peat sequence is covered by fluvial silt and sand deposits. The NKB sequence documents the Ner valley as a dynamic system during the Late Glacial and the Holocene. Local ecosystems of this oxbow have remained under a much stronger pressure of climate changes than palaeolakes and wetlands located on uplands in the Lódz region. |
