No Deer is an Island.
“By about 12000 BC plant cover began to appear in Ireland. For a thousand years, Ireland was a place of open meadows. Possibly still not an island, Ireland begins to take shape about 12,000 to 11,000 radiocarbon years ago (perhaps 11500 to 10000 BC). The following map gives a little more detail of the peninsula that would become the British Isles as the sea levels continued to increase.”
