NHER 61544 (Cropmark and Earthwork record) - Site of probable post-medieval plantation ridges

February 2017. 'Brecks from Above' and Breckland National Mapping Programme.
A series of narrow, parallel gullies, defining a block of straight 'ridges', is visible as earthworks on 1940s aerial photographs (S1). The 'ridges' may have been used for planting trees, probably in the post-medieval period. They don't actually seem to have had any height: the narrow gullies presumably defined and drained them, rather than building up an actual ridge. They are each approximately 11m wide; rather than mapping each individual gully, the block as a whole has been mapped using the convention for ridge and furrow. Imagery from a lidar survey flown in 2015 (S2) indicates that they seem to have mostly been levelled, although fragments may still survive as earthworks.
