NHER 54502 (Monument record) - Trackways of known or probable post-medieval to modern date

October 2010. Norfolk NMP.
Three earthwork ditches probably relating to post-medieval trackways are visible on aerial photographs (S1) on land to the west of the Little Ouse River, Thetford, in an area now covered by the Warren Wood plantation.
They are centred on TL 8501 8633, and the central of the three ditches is visible as part of a trackway on the first edition Ordnance Survey map (S2).

The three trackways described above are visible as much more extensive earthworks on imagery from a lidar survey (S3) [1]. As described above, the central trackway is depicted on the Ordnance Survey First Edition 6 inch map (S2) and is therefore of post-medieval date (although it could have earlier origins). The westernmost trackway, which is the most substantial and curvilinear, is not dated or shown on the Ordnance Survey map. However, it is possibly associated with two small rectilinear enclosures, which are themselves perhaps related to warrening; at its northern end lies NHER 62085, at its southern end is a second rectilinear enclosure, which has not been mapped by the project as it is depicted on the Ordnance Survey Second Edition 25 inch map (S4). The easternmost trackway is also undated but it leads from the corner of the forestry block and has the appearance of a more modern feature. As the lidar survey was flown in 2015, it is likely that all the earthworks still survive.
