List of superlative trees in the United Kingdom

Below is a list of superlative trees in the United Kingdom, containing the widest trees, the widest trees in history, the oldest trees and the tallest trees.

Widest


Presently, a regularly-updated database of the UK's widest trees by girth is kept by the user-run website Monumental Trees. Width is not indicative of tree volume, however. The largest oak tree, as well as the tallest, in the UK has long been believed to be the Majesty Oak in Kent, however its 12.2m girth is exceeded by multiple trees in the UK. Similarly, the Major Oak from Sherwood Forest, another huge oak tree in the UK, also does not make the list.

Historically the widest
Many of the UK's former largest trees have fallen victim to age, weather, or arson. Some of them have fallen apart into distinctly multiple trunks. This list also considers multi-stemmed trees.

Oldest


Several trees in the UK, all of them European yews, are thousands of years old, and one of them has been reported as 5000 years old or more, which would mean a tree older than Methuselah(tree) in California, the current official record holder for the oldest non-cloning tree in the world. The UK also has a great share of ancient oak trees, many of which are believed to be over a thousand years old. The oldest is King Offa's Oak from Windsor Great Park at 1300–1500 years old.

Tallest
The tallest tree in the UK is a non-native Douglas fir in Scotland with a height of 66.4 meters- significantly taller than the UK's tallest native tree- a 45 meter tall European Beech growing at the River Derwent in Derbyshire.
