The heritage impact assessment has been informed by a study area of approximately 500m from the boundary of the Site. This provides a brief historical and landscape background for the Site, considered appropriate within the context of the proposed works and scope of this impact assessment. No formal heritage data requests were made. Instead, online records were analysed and refined in order to narrow the research focus onto those of relevance to the present assessment. Hence not all records are referred to, discussed or illustrated further within the body of this report, only those that are relevant to the historical development of the Site. In June 2024, Cotswold Archaeology was commissioned by Forestry England to undertake measured surveys and a heritage impact assessment in respect of a section of Bishops Dyke Park Pale Scheduled Monument in the New Forest, Hampshire. The report was commissioned in connection with safeguarding works to an existing breach in the monument. These works were undertaken to enable machine access for vital wetland restoration work on the nearby mire at Penny Moor. The measured surveys were undertaken using aerial photogrammetry, aerial LiDAR and terrestrial conventional survey. The resulting outputs were used to inform a before and after condition assessment, as well as an assessment of impacts. A review of online resources revealed evidence for prehistoric activity around the Site. This included Scheduled Bronze Age round barrows located approximately 250m to the north of the Site, as well as undated earthworks of likely prehistoric date directly to the north and east of the Site. Bishops Dyke Park Pale forms the larger part of Site. It is a medieval deer park boundary, thought to have been constructed during the mid-13th century. As a Scheduled Monument it is considered to be of high heritage significance and national importance. The initial survey found the breach to be in poor condition with the ground surface badly eroded, slumping of the bank terminals, and erosion to the top of the western bank terminal. The former flanking ditches were just discernible, as shallow linear depressions; partly water filled. The safeguarding works entailed the creation of a shallow ramp through the breach, measuring 18m by 4m and up to 0.5m high. Importantly, the works required no sub-surface impacts and no truncation of the existing earthwork. The ground surface was protected with a geotextile, overlaid with a geogrid, stone rubble and translocated grass turfs. In terms of physical impacts, it was concluded that the works provided clear heritage benefits to the heritage significance of Bishops Dyke Park, through the protection of surviving archaeological deposits within the Site, as well as curtailing ongoing erosion to the former ground surface and to the bank terminals. No harm was found to the Scheduled Monument as a result of the safeguarding works, despite some changes in appearance. An assessment of non-physical impacts was also undertaken. Given the scale, height and form of the safeguarding works, it was established that the proposed development would not impact upon the settings of any heritage asset within the environs of the Site.
