Picket Mire

Summary

AI generated summary
Archaeological monitoring was carried out on 15 July 2025 during stream restoration works at Picket Mire near Picket Post in the New Forest. The work involved mechanically removing a section of the northern bank of a semi-rectangular post-medieval banked enclosure and infilling the associated ditch, causing total loss of that section. Prior to the groundworks, a heritage impact assessment recommended preservation by record, including a measured survey and historical research. Wessex Archaeology’s survey and research concluded the enclosure was a domestic encroachment on Crown land built in the late 18th century, around the 1770s, and shown on historic maps from about 1785 onwards. The New Forest National Park Authority Archaeology Team monitored all groundworks and recorded the process with photographs. No archaeological artefacts or significant remains were found during the works.

Picket Mire – September 2025

Archaeological Watching Brief Statement

Summary:

On 15 July 2025, the New Forest National Park Authority’s Archaeology Team undertook archaeological monitoring of the bank removal and ditch infill at Picket Mire, Picket Post in the New Forest, located at NGR 419070, 106348 (Fig. 1). These groundworks were carried out as part of stream restoration works for the New Forest Higher Level Stewardship scheme. No artefacts of archaeological significance were encountered during the works.

The site:

The Semi-rectangular (approx. 90x60m) Post Medieval banked enclosure, aligned NNE-SSW on its long axis, is located 170m North of Picket Post (service station) on the A31 NGR 419070, 106348 (Fig. 1). The enclosure reduces in width at its northern end and is formed by a bank (up to +1m high by +1m wide) with outer ditch still extant in places, enclosing approx. 0.5 hectares. The bank and ditch at the northern end are damaged and less visible and there are possible traces of some internal features.

Prior to the ground works Wessex Archaeology was commissioned to conduct a measured survey (Fig. 3) and historical research of the enclosure. The findings showed that this was a domestic enclosure, encroachment onto Crown Lands, constructed in the late 18th century, around the 1770s, by Joseph Agust and his son John, (Wessex 2025). The enclosure was first mapped on the Drivers Map c.1785 and then on subsequent OS 1st - 3rd Edition maps.

Pre-ground works:

The groundworks were carried out as part of stream restoration works for the New Forest Higher Level Stewardship scheme. The proposed works involve the removal of the surviving remains of the northern enclosure bank and ditch via mechanical excavation and removal of bank material, grading and levelling.

Prior to work commencing a bespoke Heritage Impact Assessment was undertaken, (NFNPA March 2025). The proposed works would result in the total loss of this section of the enclosure, Fig. 2, the following recommendations were made:

  • A metric survey - The enclosure is surveyed to capture a full record of the extant earthwork features forming the enclosure, along with any internal features.
  • Historic Research – A small amount of historical research is conducted with the aim of establishing a start and end date for the enclosure along with any other details that can be gained.
  • A report illustrating the results of the survey and the finding of research conducted.
  • A digital delivery of the survey data, in an appropriate format (to be agreed).
  • Reason:
    • Preservation by record of the area of proposed total loss of part of this feature (the enclosure).
    • The production of an illustrated and informative report of the site to capture the full enclosure to facilitate future research and understanding of the site.

The findings of the survey and research were issued in June 2025.

Following the metric survey and historical research it was determined that all groundwork should be monitored by a qualified archaeologist to record any archaeological features or artefacts encountered.

Results:

The groundworks consisted of the removal of a section of the northern enclosure bank and the infill of the associated ditch using an excavator, resulting in the total loss of this section of the enclosure.

All groundworks were monitored by the NFNPA Archaeology Team. Site photo and working photographs can be seen in photos 1-7.

No artefacts of archaeological significance were encountered during the works.
