  • In natural wood land areas for a consistant appearance.
  • Where there is planting through the bark and it is used as a mulch as much as a decoration.
  • Amongst heathers and prickly subjects where you do not want to put your hands.
  • Some people use bark as a cushion where children may fall but animals and insects can make the bark less than perfect.
