Pre-agricultural plant management in the uplands of the central Zagros: the archaeobotanical evidence from Sheikh-e Abad

Prior to the emergence of agriculture in southwest Asia, sedentarising human communities were experimenting with a diverse range of wild plant species over a prolonged period. In some cases, this involved the cultivation of species that would go on to be domesticated and form the foundation of future agricultural economies. However, many forms of plant use did not follow this trajectory, and in multiple places farming was only taken up later as an established ‘package’. In this paper, we present new archaeobotanical evidence from the Early Neolithic site of Sheikh-e Abad in the central Zagros of western Iran. Sheikh-e Abad is unique in being the only settlement known to date within southwest Asia that lies at an altitude above 1000m and which has occupation spanning the agricultural transition. Thus, it provides a rare opportunity to examine pre-agricultural plant management strategies in an upland zone. Our analyses of the plant remains from Sheikh-e Abad suggest that from its earliest occupation inhabitants were unconsciously ‘auditioning’ a suite of locally available wild grasses which ultimately were never domesticated. We discuss the possible reasons for this from a socio-ecological perspective, considering both the biology and ecology of the plant species in question, as well as the ways in which they were potentially managed

Anthracological analysis from Kovacevo, southwest Bulgaria: woodland vegetation and its use during the earliest stages of the European Neolithic

Wood charcoal analysis from Kovacevo in southwest Bulgaria, one of the earliest Neolithic sites in southeastern Europe, provided information about the first stages of anthropogenic impact on vegetation during the Early Neolithic (6159–5630 cal b.c.). Deciduous oak was the most abundant and frequently used taxon in the wood charcoal assemblages. Cornus charcoal was also abundant, probably connected with the use of its twigs as building material in wattle and daub structures. The dominant deciduous oak forest was opened during the Kovacevo I period, as shown by evidence from the Kovacevo Ia and Kovacevo Ib occupation phases. Other types of vegetation, like Black pine (Pinus nigra) woodland, riverine forests and some sub-Mediterranean elements, were used only sporadically, indicating high and sustained availability of wood resources in the oak forests. Anthropogenic impacts were gradual, a pattern that matches contemporary studies elsewhere in the region.status: publishe
