The ecological value of dry stone walls can be described from two perspectives:

• Seen from close up the focus is on the ecological value of the individual wall as a habitat for various animals and plants.
• Seen from afar the focus is on the ecological value of the network of different walls in the landscape. The drystone walls form ecological stepping stones in the landscape among other structures (hedges, rough pastures, water structures, etc.).

The ecological value of dry stone walls is high in both perspectives.
