A tree surgeon working as a contractor for London's Lambeth council trims high ash branches and boughs in Ruskin Park. Distant Edwardian period homes can be seen with blocks of flats in the Loughborough Estate are beyond. The man is tethered to safety harnesses and he swings himself across the large tree trimming and cutting the heavier and less stable arms of the plant's surfaces. Councils like Lambeth take the health of their public park's trees very seriously after incidents of falling parts onto innocent passers-by, with resulting injuries and legal action.
