Progress on the new Tree Management Centre at Westonbirt Arboretum – the 20m trusses from green Corsican Pine grown on site are well underway. The bottom chords use the natural curvature of the tree, and the members were all hewn by hand on site by volunteers. The scale of the members is really only apparent when compared with the size of a person – and then their sheer scale becomes apparent. Charley Brentnall is leading the build, and a 130 ton crane will be required for the lift.
