5. Llangernyw Yew (4,000-5,000 y/o)

This huge Common Yew can be found in the churchyard of St. Digain's Church in Llangernyw, Wales. In 2002, in partnership with the Yew Tree Campaign, David Bellamy used methods such as radiocarbon dating to determine this ripe age! It has been designated by the Tree Council as one of the Fifty Great British Trees, as a tree of national heritage.
