The fieldwork comprised the excavation of eleven trenches 30m long and 1.8m wide, in the locations shown on the attached plan (Figure 2). Trench 10 was moved 5m south to avoid modern earthworks, and the southern end of Trench 11 was also moved 7m west due to the earth works, with the approval of Eliza Alqassar. Trenches were set out on OS National Grid (NGR) co-ordinates using Leica GPS and surveyed in accordance with CA Technical Manual 4 Survey Manual. All trenches were excavated by mechanical excavator equipped with a toothless grading bucket. All machine excavation was undertaken under constant archaeological supervision to the top of the first significant archaeological horizon or the natural substrate, whichever was encountered first. Where archaeological deposits were encountered they were excavated by hand in accordance with CA Technical Manual 1: Fieldwork Recording Manual. Deposits were assessed for their palaeoenvironmental potential in accordance with CA Technical Manual 2: The Taking and Processing of Environmental and Other Samples from Archaeological Sites. All artefacts recovered were processed in accordance with Technical Manual 3 Treatment of Finds Immediately after Excavation. The archive and artefacts from the evaluation are currently held by CA at their offices in Andover. Subject to the agreement of the legal landowner the artefacts will be deposited with Buckinghamshire County Museum (AYBCM : 2018.43), along with the site archive. A summary of information from this project, set out within Appendix C, will be entered onto the OASIS online database of archaeological projects in Britain. An archaeological evaluation was undertaken by Cotswold Archaeology in April 2018 at the site of Weston Mead Farm, Aston Clinton, Aylesbury, Buckinghamshire. Eleven trenches were excavated. A total of four archaeological features were discovered spread within Trenches 1, 7 and 11. A single ditch was identified in Trench 1 which contained modern CBM, Trench 7 contained a single gully which contained Early Prehistoric pottery and Trench 11 contained an undated gully and a ditch. In the field immediately to the west of the site Wessex Archaeology found several Early Prehistoric features. These included a Neolithic pit and a Bronze Age pit and ditch. As well as these features Bronze Age pottery from the subsoil during the evaluation may suggest dispersed Early Prehistoric activity in the general area.
