The region known as Doggerland, now submerged under the North Sea, was once home to temperate forests about 16,000 years ago, predating the expansion of similar forests in Britain and northwest Europe after the final glacial retreat around 11,700 years ago. Recent studies show that Doggerland was rich with trees like oaks, elms, and hazelnuts, indicating a vibrant ecosystem that thrived until it was gradually submerged, contrary to earlier estimates that suggested it was completely flooded 7,000 years ago. The new findings suggest the submergence likely occurred around 6,000 years ago, highlighting the area’s historical significance and ecological diversity.

A team of researchers utilized ancient sedimentary DNA extracted from the seafloor to reconstruct the terrestrial ecosystem that once flourished in southern Doggerland. Their findings provide valuable insights into the types of wildlife that inhabited the region, including evidence of wild boars, elk, bears, and aurochs, further emphasizing the area's ecological richness before its disappearance beneath the waves. This research sheds light on how the landscapes of the past were profoundly different from today’s, illustrating the impact of climate change and sea-level rise on ancient habitats.

The new revelations about Doggerland not only enhance our understanding of prehistoric environments in Europe but also raise questions about how rising sea levels might affect current coastal ecosystems. The study serves as a reminder of the dynamic nature of landscapes over time, illustrating the importance of preserving our modern ecosystems and recognizing the historical changes that have shaped our planet’s biodiversity.
