NHER 51711 (Cropmark and Earthwork record) - Post medieval to modern boundary bank

July 2008. Field visit.
Undated low bank. Where it was visible in the forestry plantation/amongst thick bracken, it measured 7m to 8m wide by up to 0.2m high. It may indicate the edge of a path or the boundary between heath and arable, as shown on the Ordnance Survey 1st edition 6 inch map (S1).

The boundary bank described above, which is probably of post medieval to modern date, is visible as an earthwork on lidar imagery from a survey flown in 2015 (S2). It appears to correspond with a boundary depicted on modern and historic Ordnance Survey maps (for example, S1), indicating its post medieval to modern date. A more extensive network of banks, presumed to be of earlier date, is evident as earthworks to its southeast (NHER 31217 for example). As it is depicted on modern and historic Ordnance Survey maps, it has not been mapped by the project.
