Origin and Evolution of a Peat Bog From Northeastern Romania

Peatlands are highly sensitive ecosystems that respond to hydrological, climatic, and geomorphological changes. In this study, we investigate the origin and historical evolution of a peatland located in Northeastern Romania, on the Suceava plateau. Our approach includes the analysis of historical maps and physical characteristics of both the peat (grain size, LOI - loss on ignition) and water (pH, dissolved oxygen, electrical conductivity). Our findings suggest that the development of this peatland has been more prominent along the surface than the depth. The presence of gravel and sand at the base of the peat deposit, along with surface morphological evidence, supports the hypothesis that this peatland originated in an ancient paleomeander. pH analysis indicates that the peatland is mesotrophic, while granulometric and LOI analyses suggest a fluviogenic origin.The significant changes observed in the sedimentary structure of the peatland may be attributed to climate change, with potential anthropogenic influences over the past 50 years. Furthermore, our study contributes valuable insights to geomorphological research in the Suceava valley, revealing visible changes spanning the last 250 years.
