    The Pre-Boreal began with a sudden rise in temperature that abruptly changed this ecosystem. Forest replaced the open lands in Europe, and forest-dwelling animals spread from southern refugia and replaced the ice-age tundra mammals; new climax ecosystems developed. The old fauna persisted in Central Asia, but were soon hunted out, as they were ...

    The Younger Dryas (YD, Greenland Stadial GS-1) [2] was a period in Earth's geologic history that occurred circa 12,900 to 11,700 years Before Present (BP). [3] It is primarily known for the sudden or "abrupt" cooling in the Northern Hemisphere, when the North Atlantic Ocean cooled and annual air temperatures decreased by ~3 °C (5.4 °F) over North America, 2–6 °C (3.6–10.8 °F) in Europe ...

    The pre-Boreal period was followed by the Boreal period, which began around 7,500 BC and saw a much warmer and drier climate. Accordingly, the composition of the wildwood began to change with the arrival from continental Europe of tree species that were able to thrive in the new conditions.
