In April 2019 Oxford Archaeology carried out a trial trench evaluation as part of wetland regeneration scheme at Eythrope Meadows, Waddesdon Estate, Buckinghamshire on behalf of the River Thame Conservation Trust. The site is situated on the floodplain of the River Thame directly adjacent to and within the setting of a medieval moat site known as 'moated site 650m south of Beachendon Farm' (NHLE: 1018671). Four trenches were excavated within the footprints of the proposed fish ponds and management channels, but only uncovered a single undated ditch, possibly modern. Test pits dug at either end of each trench to investigate the underlying floodplain sequences, revealed a sterile alluvium sequence extending below the maximum impact depth but encountered no archaeological remains. The archaeological potential of the site is therefore considered to be low.
