A UNIQUE project celebrating the life of a single oak tree has reached its finale.

All 40 items made from the felled Blenheim oak were brought together for the first time at the Art in Action festival at Waterperry.

The products range from the waste sawdust used by chef Raymond Blanc to smoke salmon, to a throne chair worth £6,000, and dozens of other items including a house, boat and woodchip for bioenergy.

The 222-year-old oak was felled on the Blenheim Estate in January 2010, and donated to the Sylva foundation by the Duke of Malborough.

The project aims to illustrate the importance of woodlands and wood in modern society.

OneOak tree is also the most studied oak tree in Britain, having been weighed, measured with lasers to create a 3D model, and had its carbon content estimated. Chief executive of the Sylva Foundation and project co-ordinator Gabriel Hemery said: “We felt that the public have lost touch with woodland management.

“People will ask why a tree is being cut down, but they will happily go to a furniture store and buy tropical hardwoods. Normally a tree would be used for four things maximum, and we wanted to celebrate some of the other uses.”

Mr Hemery, a chartered forester and environmentalist, added: “Oxfordshire is one of the least wooded counties, but we have got some of the top wood designers.”

The tree was planted in 1788, the same year Mozart composed his final symphony.

Now it has been worked by dozens of artists, sculptors and photographers totalling more than 40 different products.

Richard Fox, a sculptor from Poffley End, near Witney, said: “It’s just amazing to see so many people involved in one project.

“I made something that is the most complicated sculpture I have made yet. I thought this was a worthwhile reason to make something I haven’t made before.

“I have spoken to lots of people and the response has been really positive. It just opens your eyes to what can come from one tree.”

The OneOak tree project will now exhibit for six weeks at Blenheim Palace, then six weeks at Royal Botanic Garden Edinburgh.
