Designated as ancient and semi-natural woodland, this woodland is depicted on the 1st Edition OS map of 1854 as 'Armroyd Holt'. It is first recorded as Peter Wood on the 1892 OS map. The woodland has been reduced by approximately half since 1854 and much of this clearance has taken place in the latter part of the 20th century. The current compartmentalisation of the wood may suggest a history as a coppice woodland. Legibility of the previous character is fragmentary as the area is still wooded.
