James Canton talks with Kathryn Ryan about the two years he spent visiting and studying an 800 year old oak tree in Essex.
The Honywood Oak in Coggeshall was a sapling when the Magna Carta was signed in 1215, and once stood among a forest of 300. It is the lone survivor in that field today.
James Canton's book The Oak Papers is a meditation on the life of the tree, the wider natural world and humans' connection with them. He says humans have had a close association with oak trees since pre-history.
