Subsequent to aheritage statement a geophysical survey was carried out on the site. This identified a number of linear and discrete anomalies which might be archaeological features. Based on those results the Buckinghamshire County Council Historic Environment Service advised that an archaeological evaluation would be required in order to further identify the nature of the site's potential archaeological resource. Albion Archaeology was commissioned to undertake archaeological trial trenching and to undertake the fieldwork. The trial trenching revealed a c. 12m-wide trackway or drove road (which contained a few sherd of Iron Age pottery) and a small number of contemporary and undated pits and ditches which may be field boundaries and quarries. The relatively small number of artefacts retrieved from the features and the absence of refuse deposits suggests they were some distance from any settlement focus. The exception was one pit at the western edge of the site which contained a fairly large quantity of animal bone and Roman pottery. The earthworks of medieval ridge and furrow cultivation were observed throughout the site. No early prehistoric or post-medieval features were revealed. It is possible that the drove road dates from the Roman period and is associated with a Roman settlement excavated at Vicarage Gardens to the south of St James's Church, Bierton. Fieldwalking to the west and north of the area also retrieved Roman artefacts suggestive of the existence of further settlements.
