The Mammoth Steppe reached from Western Europe all the way across Siberia, and further towards North America. 10,000 km long, 2,000 km wide. Enormous. In large parts of the ice age, Denmark and England formed the north-western part of the Mammoth Steppe. The water level in the seven seas was 100 meters lower than today, which means that there were no North Sea. You could even walk to England, if you wanted to. On the way you would meet herds of woolly mammoths, woolly rhinoceros, Irish Elks, reindeer, steppe bison, Saiga antelope, muskoxen, and wild horses. A rich wildlife.
The Mammoth Steppe had a rich wildlife with many herbivores. It was not just the climate that upheld the Mammoth Steppe as an open, flowering landscape. It was also the animals’ grazing, their wear, and their refurnishing of nutrients, just like present-day nature management in e.g. Mols Bjerge.
