DigVentures was appointed by the Yorkshire Wildlife Trust to undertake a community-based archaeological investigation at Loversall Carr, Potteric Carr nature reserve, Doncaster, South Yorkshire (NGR: SK 59162 99791), consisting of small-scale archaeological interventions. Fieldwork took place between the 1st and 2nd April 2023 investigating the extent, nature and significance of the surviving archaeological remains through a programme of small-scale targeted trial-trenching. The overarching aim of this fieldwork was to provide baseline information to contribute to the future management and presentation of the site, whilst creating multiple educational and participatory learning experiences for community participants. Three test pits were excavated in a community focussed archaeological investigation at Loversall Carr, Potteric Carr nature reserve (NGR: SK 59162 99791), targeting features interpreted from aerial photograph and geophysical surveys indicative of a potential tri-vallate late Iron Age or early Romano-British enclosed settlement. Test Pit 1, internal to the settlement enclosure, revealed evidence of probable domestic occupation in the form of a number of small refuse and storage pits as well as a possible linear ditch or drainage gully. The cut marks present on animal bone recovered from these features suggests that at least one of the functions of the site was as a place for living, as evidenced by activities such as processing food, cooking, eating and the discarding of resulting waste products. Test Pits 2 and 3 focused on two of the three parallel boundary ditches enclosing the settlement itself. Both ditches were confirmed to contain waterlogged deposits of high paleoenvironmental potential. The presence of waterlogged deposits within the enclosure ditches of the settlement itself is particularly intriguing and suggests that the immediate surrounding landscape in the Iron Age was almost certainly a marsh environment. Such a large tri-vallate enclosure (at least 2.6 hectares) set within a low-lying marshland landscape draws parallels with the poorly understood site-type of Iron Age marsh forts, with the nearby nationally important site of Sutton Common just north of Doncaster being at present the only excavated and best understood example in the country. In total, the project welcomed 17 participants who joined the archaeological team in the trenches and succeeded in attracting a new audience for archaeology, with 59% of participants havi...
