Charcoal Hearth Remains as Environmental Archives: An Interdisciplinary Study at Poggio di Montieri, Italy

ABSTRACTThis contribution presents interdisciplinary research on charcoal hearth remains carried out at Poggio di Montieri, Central Italy, a hill heavily exploited in the Middle Ages for the extraction of silver-bearing ore, and then managed until the nineteenth century with a multiple land use system based on pasture. Linking together pedological and archaeological surveys with anthracological, dendro-anthracological and chemical analyses, as well as with information from historical texts and maps, this research outlines the environmental dynamics that occurred in this area in the last few centuries. Although ore processing undoubtedly required large quantities of charcoal as fuel, no evidence of charcoal hearth remains from the Middle Ages have been found, while at least two charcoal production phases, starting from the seventeenth century, were individuated. Despite an increase in charcoal production at the end of the last phase, in the eighteenth–nineteenth centuries, no over-exploitation of the forest resources at Poggio di Montieri was documented. The lack of such an expected over-exploitation could be due to the use of wood from pruning and shredding, which allowed the sustainable management of the forest resource and was the legacy of the multiple land use systems of previous centuries.KEYWORDS: pedologydendro-anthracologyforest soilhistorical ecologycharcoal kilnstopographic analysis Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThe author GM has benefited a Marie-Curie COFUND postdoctoral fellowship, co-founded by the European Commission and the University of Liege (ref. number: 600405).

PesciniV. Pescini is an Environmental Archaeologist, specialising in anthracology and archaeobotany. Her research focuses on the study of agro-sylvo-pastoral practices and their environmental effects through time. She received her Bachelor and Master’s degrees in Medieval Archaeology (2010) and Archaeobotany (2013) respectively at the University of Siena (Italy). In 2019 she completed her PhD in Historical Geography which was followed by a post-doctoral position at the University of Genoa (Italy). In 2020 she was awarded a Juan de la Cierva – formation (FJC2019-040406-I) scholarship at the Catalan Institute of Classical (ICAC) of Tarragona and in 2022 she obtained a Ramon y Cajal junior (RYC2021-034621-I). Throughout her career she has collaborated in interdisciplinary research projects with archaeologists, naturalists, historians and geographers.G. CertiniG.
