The approximate age of this tree is calculated by estimating its lifetime growing conditions and measuring its girth.[1]

The age calculations has been made on the basis that this ground is between "average" and "good"

Doing the calculation on the basis of this being an average site, the tree is estimated to be approximately 294 years old in 2015, and therefore started growing around 1721. Doing the calculation as good site the tree is estimated to be approximately 274 years old in 2015, and therefore started growing around 1746.

General tree description

Quercus robur is a large deciduous tree with a wide spreading crown. In maturity it can reach a height of 20 to 40 metres, and a girth of over 4 metres, exceptionally 12 metres. It has a long lifespan and commonly lives to several hundred years old. There are examples of Quercus robur reaching ages of more than a thousand years. The leaves are around 10cm long with 4-5 deep lobes with smooth edges, and they have very short stalks. Flowering occurs in mid spring, and the fruits, in the form of acorns, ripen in autumn. They come singly or in groups of up to three in cups on a slender stalk.
