[1] The south western area between the River Wye and Kinder Scout was relatively open country, which was enclosed by a low wall, sufficient to keep out cattle and sheep but allow the deer to roam.
As well as his custodianship of the Forest, William also held a number of manors that formed part of what was recorded in the Domesday Survey as the Honour of Peverel.
When his son Henry IV ascended the throne the Honour of the Peak passed to the crown along with all the other holdings of the Duchy of Lancaster, such as Duffield Frith.
Subsequently, the manor and forest of High Peak were leased in perpetuity to the dukes of Devonshire.
Records document the deer, wild pigs, wolves, horses and sheep in the forest.
