This tree is at River View, Gabalfa
The approximate age of this tree is calculated by estimating its lifetime growing conditions and measuring its girth.
The 1880 Ordnance Survey map shows that historically the ground was part of the Gabalva House estate,[2}[3} and the existence of large Lime and Plane trees nearby suggests that the trees were formally planted. The age calculation has been made on the basis that this ground is a "good" site for this tree. The ground is considered good because it is an open site quite near a river bank. On this basis, the tree is estimated to be approximately 233 years old in 2022, therefore started growing around 1790.
General tree description
Castanea sativa is a fast growing, large tree growing up to 36 metres tall. It has vertically-ridged, rough, grey-brown bark and dense glossy foliage. The leaves are 20cm long and elliptic with 20 pairs of straight parallel veins each ending in a 'saw' tooth. The flowers are bisexual catkins, female at the base and male at the tip. The conspicuous male sections are 15 to 20cm long and yellow or creamy white with an unpleasant odour. They mature in mid summer, then fall away leaving the female catkins to develop into spiny fruits (chestnuts) in autumn. A good crop of chestnuts is only produced in a warmer than average summer.
