Any approach to the economic organization of a society depends on our knowledge of the productive forces and relations of production involved. In archaeology, this line of research requires an ...analysis of the technical quality and quantity of the means of production, as well as their spatial distribution and contextualisation. Macrolithic artefacts constituted the means of production in many of the productive processes of past communities, from the Neolithic period to the end of prehistory. This article seeks to utilize macrolithic data to gain a more comprehensive understanding of the economic organisation of the Chalcolithic communities in the southern half of the Iberian Peninsula between c. 3100 and 2200 cal BC. These communities produced one of the most outstanding, but at the same time puzzling archaeological records known in later prehistory. The main aim of this exploratory approach, the first of its kind, is to determine if the different forms of occupation of the Chalcolithic, namely monumental, ditched enclosures, fortified and unfortified hill-top settlements, and simple, open settlements were distinguished by specific modes of production. This issue is crucial to the on-going debate about the meaning and relevance of the notion of
social complexity
in the context of Chalcolithic societies and their political organisation. Our study describes the productive forces of the Chalcolithic settlements as highly variable, both in the type of productive tasks performed and in their intensity, and such variability is not explained by aspects like geographic location, form of occupation, or monumentality. The observed wealth and productive diversity, without signs of marked social hierarchies, emerge as a characteristic feature of what can be defined as
cooperative affluent societies
.
Exceptional components of the cultural landscape of Central Europe include archaeological sites, e.g., castle ruins, prehistoric or medieval fortified settlements, other settlements and burial ...mounds. The plants associated with them help us explain the processes of species persistence on habitat islands as well as the process of naturalization of crop species, which escape from fields or are abandoned. This study describes the flora of a medieval fortified settlement in Giecz (Wielkopolska region, western Poland), presents plant indicators of former settlements (relics of cultivation), species of high conservation value, and transformations of the vascular flora of this settlement over a few decades. Field research was conducted in 1993–1994, 1998–1999, and 2019. At the study site, 298 species of vascular plant species were recorded, and nearly 70% of them (201 species) have persisted there over the last 20 years. The flora includes seven relics of cultivation (Artemisia absinthium, Leonurus cardiaca, Lycium barbarum, Malva alcea, Pastinaca sativa, Saponaria officinalis, and Viola odorata), 5 species threatened with extinction in Poland and/or Wielkopolska, and 53 species of least concern (LC) according to the European red list. We have attempted to explain the floristic changes. The archaeological site in Giecz is of high conservation value, very distinct from the surrounding cultural landscape because of its specific flora, and composed of species from various habitats (e.g., dry grasslands, wooded patches, meadows, aquatic and ruderal habitats), including threatened, protected, and relic species.
