Climate, environmental, and hydrological changes are an increasing concern, as they affect both ecosystems and human well-being. By studying past changes, we can better understand the current impacts and consequences of current transformations and take informed action regarding the future. In this study, we analyzed a peat sequence from Tăul Fără Fund (Pădurenii-Țop area – Transylvanian Basin) using abiotic methods (lithology, radiocarbon dating, loss on ignition, magnetic susceptibility) and biotic methods (testate amoebae, microscopic charcoal particles) to reconstruct the evolution of the peatland and the environmental and hydrological changes that occurred over the last millennium. We identified drier periods between AD 1000–1150, AD 1400–1650, and AD 1850–1950, and wetter periods between AD 900–1000, AD 1150–1400, AD 1650–1850, and from AD 1950 to the present. Comparing our results with other studies from Romania, we found that they are relatively consistent, with local conditions at Pădurenii-Țop closely matching regional trends.
