Sherwood Forest Country Park (now a National Nature Reserve) is an iconic piece of Nottinghamshire heritage and landscape located 3km to the west of Ollerton and directly north of Edwinstowe village. The survey area covers the Country Park area which equates to just under half of the NNR. The survey work was carried out in the winter and spring months when the bracken and other vegetation had died back in order to aid visibility. The lack of foliage cover during these months also helped to improve the accuracy of the GPS readings. For the fieldwork the survey area was divided into manageable compartments to aid a systematic recording approach. Under the supervision of archaeologists from Nottinghamshire County Council, the volunteers walked the compartments in as regular a fashion as was possible given the terrain and undergrowth. Volunteers aimed to maintain a distance of around 5 metres from eachother, but in reality this was often not possible. Any features of archaeological interest were noted and recorded using a hand-held navigation-grade GPS device attached to a tablet via Bluetooth. The walkover survey recorded over 800 new points of data within the woodland of the country park. While some are of unknown date and interpretation many of them can be ascribed approximate or relative dates, and some interpretations are possible. Most of these were earthworks including pits, depressions, banks, holloways, ditches, and ridge and furrow cultivation. The survey also recorded organic features, such as ancient coppice or pollard trees, the stumps of veteran trees, and anomalous vegetation. It is clear that a woodland like Birklands has preserved a huge range of archaeological features including earthworks that have been lost to agriculture, minerals extraction and urban development elsewhere. The high-resolution Lidar data shows that there are further earthworks not recorded by the walkover survey. While woodlands are known to have potential for preservation of earthworks the concentration of archaeological features within Birklands is remarkable and exceptional. This is due to the early enclosure of the woodland and continued land-use, and to the types of management practices employed within the woodland over the centuries. It is worth noting that many of the boundaries within the wider area, including the Edwinstowe - Budby parish boundary, are on the same alignment as the Romano-British 'brickwork plan' field system identified by Malone. This raises interesting questions about both the level of continuity from the Roman landscape to the Early Medieval period, and of the dating of the creation of the hay of Birkland. It is possible to tie up some of the features within the survey area, and boundaries in the wider landscape, to the Roman field systems suggesting perhaps that there was no episode of total abandonment and later re-planning. This is different to the evidence we see elsewhere in the county, particularly in the Trent Valley, where Medieval field systems bear little relation to the Roman ones evident in crop marks. Many of the archaeological features within the woodland are sensitive to damage due in part to the soft sandstone geology. Management plans for the woodland should take this into account and take steps to minimise the damage to the wealth of archaeological information preserved within the woodland. The ‘Hayman Rooke’ enclosure in the north-west of the woodland is clearly significant and may represent a rare upstanding survival of the Roman field systems characteristic of this area and which usually only survive as cropmarks. As such it would be worth considering whether Scheduling of the site would be a wise step to ensure its continued protection.
