More than £20,000 was raised at a public auction of the works of art created during the week-long tree-carving event at Westonbirt Arboretum, near Tetbury, Gloucestershire.

The money from the Tilhill-sponsored event will go to Tree Aid, the charity working to reverse environmental degradation and poverty in Africa.

The highest price, £5,200, went to Mick Burns’s work “Hawker”, a dragonfly created from two logs of cherry. The carving consists of nine separate sections of timber – done to both conserve timber and for ease of transport.
