Climate and vegetation interactions in the Arctic reached a peak between 11 and 10 ka prior to decreasing throughout the early Holocene as changing seasonality rather than temperature alone modified landscape processes and vegetation shifts. Shifting range limits and plant assemblages were further impacted by soil type, as a result vegetation change was not controlled by climatic conditions alone. During the dramatic transformations that occurred globally throughout the late Pleistocene, the area of Beringia experienced relatively minor changes in vegetation in comparison to other parts of the world as the tundra steppe persisted in spite of cold and dry conditions. This is likely a result of the
