 The restoration of the old road to nature removed a barrier that prevented the migration of ground-nesting birds, such as woodlarks and nightjars from one part of the nature reserve to the other.Among the artefacts found was an old milestone that was discarded during the rebuilding of the road in 1826.The 1811 Ordnance Survey map was used to identify the original position of the stone where it has since been re-erected.
