Fagus sylvatica is one of the most representative trees of the European deciduous broadleaved forests, yet the impact of changing climatic conditions and anthropogenic pressures (anthromes) on its presence and distribution in the coastal and lowland areas of the Mediterranean Basin has long been overlooked. Here, we first analysed the local forest composition in two different time intervals (350–300 Before Current Era, BCE and 150–100 BCE) using charred wood remains from the Etruscan site of Cetamura (Tuscany, central Italy). Additionally, we reviewed all the relevant publications and the wood/charcoal data obtained from anthracological analysis in F. sylvatica, focusing on samples that date back to 4000 years before present, to better understand the drivers of beech presence and distribution during the Late Holocene (LH) in the Italian Peninsula. Then, we combined charcoal and spatial analyses to test the distribution of beech woodland at low elevation during LH in Italy and to evaluate the effect of climate change and/or anthrome on the disappearance of F. sylvatica from the lowlands. We collected 1383 charcoal fragments in Cetamura belonging to 21 woody taxa, with F. sylvatica being the most abundant species (28 %), followed by other broadleaved trees. We identified 25 sites in the Italian Peninsula with beech charcoals in the last 4000 years. Our spatial analyses showed a marked decrease in habitat suitability of F. sylvatica from LH to the present (ca. 48 %), particularly in the lowlands (0–300m above sea level, a.s.l.) and at higher altitudes (>900 m a.s.l). In the lowland areas, where F. sylvatica has disappeared, climate had a more uniform effect on beech distribution patterns across the entire elevation range analysed, whereas climate+anthrome and anthrome alone influenced 69 % and 84 % of the lowland areas, respectively.

Charcoal analysis, applied in sediment facies analysis of the Pecora river palaeochannel (Tyrrhenian southern Tuscany, Italy), detected the occurrence of past fire events in two different fluvial landforms at 800–450 BC and again at AD 650–1300. Taking place in a central Mediterranean district adequately studied through palaeoenvironmental and archaeological research, the investigation determined land changes, time phases and socio-economic driving forces involved in dynamic processes of fire. The fire sequences had purely anthropogenic origins and were linked to forest opening and reduction by local communities. Introduced by the Etruscans, fires dated to 800–450 BC involved mainly the forest cover on the hilly slopes, ensuring agricultural exploitation. From AD 650, fires contributed to Medieval upstream reclamation and vegetation clearing of flat swamplands. From AD 850 to 1050, the use of fire spread over a wider area in the river valley, increasing arable lands. Between AD 1150 and 1300, fires belonged to a regional forest clearance phase. Medieval fire episodes had a paramount importance in shaping and determining the character of the Tuscan Mediterranean landscape. From AD 850, Medieval fire clearing influenced regional vegetation history contributing to the decline of the dominant deciduous Quercus woodland. Open habitats became the new form of a clearly detectable agricultural landscape from AD 950. The use of fire clearing and the resulting landscape changes in the Pecora river valley depended on the political strategies adopted by Medieval authorities and marked, in fact, the progression of a cultural landscape still characterizing central Tyrrhenian Italy.

This paper presents the preliminary results of the analysis of charcoal remains from the Neolithic cinnabar mine of Spaccasasso. Cinnabar is a mineral that was used as a pigment by different cultures worldwide since the Neolithic period. Firesetting was one of the most common mining techniques used for breaking rock to extract ores and minerals from prehistoric times up to the invention of explosives. Anatomical identification of the fuelwood used for mining provides important information about ancient mining techniques. The results show a preference for the use of Erica as a fuelwood, associated with evergreen and deciduous oaks. These data are coherent with the pollen records from nearby sites on the Thyrrenian coast that show the dominance of a mixed deciduous and evergreen oak forest with elements of maquis shrubland. These results are preliminarily discussed considering the heat values and the physiological state of the most common Mediterranean fuelwoods. They suggest a fuelwood selection based on the empiric knowledge of which woody plants serve as the best fuel for firesetting by Late Neolithic Populations.

Under the aegis of the ongoing international Oplontis Project we carried out organic residue analyses on thirteen samples from eleven Dressel 2–4 amphorae recovered at Villa B at Oplontis (Torre Annunziata, Southern Italy) in order to identify their content and to characterize their visible lining. Although the content of Dressel 2–4 amphorae is usually thought to be wine, no residue analyses have been carried out until now to verify it. Analyses were carried out with Gas chromatography coupled to mass spectrometry. The results of the analyses indicate that all the amphorae were coated with Pinaceae products which had undergone different stages of preparation. Moreover, they confirm that Dressel 2–4 contained wine, or its derivatives, as wine markers were identified in all the samples. The data we obtained demonstrated that the amphorae analyzed were not new vessels, expressly made to trade the wine produced in the surrounding area, but were ready to be reused.

A multiproxy approach based on archaeobotanical, organic residue and isotopic analyses was carried out on materials from 12 Medieval archaeological sites in Tuscany (central Italy), in order to provide a diachronic overview of local diet in rural and urban sites from the mid-eighth to the fourteenth centuries AD. Archaeobotanical analyses were applied to 130,578 seeds/fruits, residue analyses involved 87 samples from cooking and storing vessels, whereas analyses of carbon and nitrogen stable isotopes included 63 human bone samples and 26 animal specimens. The results indicate that from the mid-eighth century AD, crop production was of high quality similar, to that of the Roman Age. The main cultivations were naked wheats, barley and horse bean, a diversity that attests the technological skills reached by Tuscan peasants during the whole Middle Ages. Different cereals and pulse abundantly supplemented the diet. This strategy not only ensured peasants’ subsistence in the mid-eighth century AD, minimizing the risks of environmental adversities, but it also increased crop production – from the mid-ninth century AD on, for the revived markets and trade. Between the eleventh and fourteenth centuries AD, C4 plants had a dominant role in the peasants’ diet, when the wheat production was strictly collected first by the landlords and then by the cities for their own needs. Crop production was integrated by swine farming; animal meat consumption is well documented in rural and urban populations from the ninth century AD. Wine and olive oil, considered important elements of diet in Medieval Tuscany, have a very scarce presence, but they are recorded for later periods, mainly in urban areas and in higher social classes, such as the religious and aristocratic ones. In fact, only between the twelfth and thirteenth centuries AD was the great expansion of olive groves and vineyards recorded, when cities and urban populations claim to have access to these luxury foods.

Anthracological analysis was carried out in the archaeological site of Punta di Zambrone on the Tyrrhenian coast of Calabria in southern Italy. Archaeological excavation documented at the site settlement deposits dated mainly to Early Bronze Age (EBA, 21st–18th century BC) and the Recent Bronze Age (RBA, 13th to early 12th century BC). In the phase of the EBA village, the high frequency of Olea europaea in the charcoal data suggests the tree may well have been cultivated by favouring the spread of the scant olive trees growing wild. Comparison with existing archaeobotanical data indicates that olive cultivation spread over a large portion of southern Italy from the EBA and the early Middle Bronze Age (MBA, 17th–15th century BC), thus calling into question the hypothesis of its first cultivation related to the interaction between Mycenaean Greece and local cultures in southern Italy. The early domestication event at Punta di Zambrone supports the idea of multiple independent primary events of olive domestication throughout the Mediterranean basin. In the following phase of the fortified settlement dated to the RBA, the frequency of olive charcoal diminished and the expansion of a more or less dense forest dominated by Quercus was judged to be a consequence of human depopulation that characterises the end of MBA and also a different land use of RBA. This forest increase, also recorded by other archaeobotanical proxies in the central and southern Italian peninsula, is found to be related to the diffusion in southern Calabria of the Subapennine culture, spreading from more northerly areas of Italy and bringing different economic systems and agronomic knowledge. These far-reaching changes appear to have brought to a halt the first event of olive cultivation recorded at Punta di Zambrone.

In this paper, we propose the application for the first time in the Mediterranean area of the combination of the study of chemical residues in floors and ceramics, with the aim of providing information about the activities carried out in archeological buildings. We chose the Garum Shop at Pompeii to test the method. In fact, due to the peculiarity of this archeological context, it provided an ideal case in which the activities performed are in part known, and the ceramic vessels recovered are still in situ. Floor samples were studied by means of spot tests developed in Mexico aimed at identifying the presence of phosphates, fatty acids, and protein residues, while the organic residues preserved in the ceramic matrix of amphorae, dolia, and other ceramic vessels were studied by gas chromatography coupled with mass spectrometry. Moreover, we integrated the data obtained with specific studies directed at better identifying the solid residues found inside two of the amphorae studied: botanical studies of fruit stones recovered in a Dressel 20 amphora and the characterization of the lime preserved in an African amphora. The research allowed for the identification of the traces of some of the activities performed, such as cooking and producing garum in the floors of the building, and the use and re-use of amphorae and dolia before the Vesuvian eruption.

Anthracological analysis has been carried out in the Medieval site of Miranduolo, a rural settlement in southern Tuscany with a sequence of occupation between the 7th and 14th century AD. Between the 7th and mid-9th century AD, during the phase of a Lombard farming village, the strong presence of Castanea sativa as timber for building showed that chestnut was the preferred species for carpentry and fuelwood, suggesting coppice management of chestnut woods for timber production. The Miranduolo data, set against the archaeobotanical data in the literature, rejected the hypothesis of chestnut cultivation as a fruit tree and corroborated the hypothesis that the plant was initially used for timber production during the Early Middle Ages, continuing the woodworking tradition of the Roman period. From the mid-9th century AD, during the Carolingian feudal system, chestnut in the feudal estate of Miranduolo ceased to be used for building and firewood, while deciduous Quercus was preferred. At the same time, chestnut fruits began to be picked and kept in warehouses at the disposal of the feudal lord, suggesting the management of chestnut woods for fruit production. Comparison with existing archaeobotanical data revealed that chestnut cultivation for fruits began in this period in other Italian regions also, encouraged by different economic systems. From the 10th century, in Miranduolo chestnut was exploited both for timber and fruit suggesting the abundance of this resource in high managed stands. Comparison with coeval archaeological sources, archaeobotanical data and pollen records suggested from this period the strong expansion of this species that gradually took place throughout central and southern Italy, becoming a ‘multifunctional’ high-forest. The current chestnut forest landscape in central Italy is thus of human origin, expanding and changing over about 1000 years of cultivation.

This paper presents the results of inter-disciplinary work drawing on archaeobotanical and archaeometric studies to trace the agroforestry landscape and the supply economy at the vicus of Thamusida in north-west Morocco at the border of the Roman Empire. The available data indicate the self-sufficiency of the settlement in both forestry and agricultural products throughout the period investigated from the end of the 1st century BC to the beginning of the 4th century AD. Charcoal data testify to the presence of a Quercus suber forest in the close surroundings of the site and its exploitation for a variety of forestry products such as timber, fuelwood, cork, and probably also leaves and acorns to feed livestock. The overwhelming presence of Q. suber in the archaeological layer investigated clearly indicates that this forest was under human influence prior to Roman occupation and was already partially degraded. Charred seed and fruit remains suggest that the diet of both troops and civilians was mainly based on locally grown products and that all the inhabitants of the site had access to good cereals such as barley, naked wheats and pulses with large seeds such as horse bean and pea; quality fruits, such as olive and grape, were also produced locally for fresh consumption. Organic residue analyses of the contents of ceramic vessels and plastered vats allowed archaeobotanical data to be complemented, thereby shedding light on some of the imports at Thamusida. Despite the remote location of this settlement, imported goods such as oil and wine were transported here in amphorae from different parts of the Empire.

Although domestication of the grapevine (Vitis vinifera L.) has been extensively documented, the history of genotype selection and evolution of vineyard management remain relatively neglected fields of study. The find of 454 waterlogged grapevine pips from a well-dated Etrusco-Roman site in the Chianti district (Tuscany, Central Italy) is an extraordinary chance to gain insights into the progress of viticulture occurring in a key historical period in one of the world's most famous wine regions. The molecular and geometrical analyses of grape seeds showed (a) the presence in the site of different grapevine individuals and (b) a sudden increase in pip size, occurring at around 200 BC, whic explainable by the selection and introduction of new varieties. In this period, the Etruscans settlers in Chianti were stimulated by northward-expanding Roman culture to use novel vineyard management practices. We hypothesize that one of the most important innovations may have been the introduction of pruning, inducing vine physiological conditions more favorable to pip growth. Such changes were the consequence of specific entrepreneurial choices made by the Romans in a period of economic investment in grape cultivation and wine making to satisfy the increased trade demand after the conquest of the Central-Western Mediterranean basin.

Plant macrofossil (carpological) and morphometric analyses were carried out on plant remains from the medieval castle of Miranduolo, Siena, a rural settlement in central Italy with a long sequence of occupation between the 8th and the 11th centuries a.d. The presence of Triticum aestivum/durum and Vicia faba var. minor from the first phase of the Lombard farming village suggests continuity with the agricultural tradition of the preceding Roman world, and the use of good cultivation techniques that allowed quality yields to be obtained from rather poor soils. At the same time, the significant presence of the primitive cereal T. monococcum, compared with the archaeobotanical literature of north-central Italy, allows to us consider it as a “cultural” element of Lombard farming. In the next cultural phases, with the Carolingian manor and then with the feudal castle, the stable presence of T. aestivum/durum and the reduction of T. monococcum in favour of more productive cereals such as Secale cereale and Hordeum vulgare indicate a further improvement in productivity. This is also confirmed by the appearance of fruits and nuts such as Castanea sativa, Vitis vinifera and Prunus persica. The increase in caryopsis sizes of T. monococcum and T. aestivum/durum in the transition from the village to the manorial phase is a consequence of the improvements in farming. The decrease in caryopsis size of T. monococcum from the manor phase to that of the castle testifies the decreasing importance of this cereal. The good date resolution of this research allows us to detect the crops, the storage and the processing practices, as well as the changing role of crop plants in the rural economy. This highlights the geographical, historical-cultural and political factors of the medieval transition from the Lombard to the Carolingian and then to the feudal period in central Italy.

Anthracological analysis has been carried out in three sites located on the Tyrrhenian coast of central Italy (ancient northern Etruria: the castle of Donoratico, the town of Populonia and the port of Alberese), spanning between the Roman Republican Period and the Late Middle Ages (3rd century bc–13th century ad). The integrated comparison of three different local charcoal data with the regional pollen and microcharcoal data available from northern Etruria showed well that vegetation changes are completely independent of climate and strictly connected to economic and social dynamics characterising the history of this part of central Italy. Indeed, Quercus ilex forests progressively retracted from the 3rd century bc in favour of open macchia formations just during the growing human impact of the Romanisation when intensive agriculture and livestock grazing characterised the economic system. The transition from macchia to deciduous Quercus forest at the end of the Roman Period from the mid-4th to the mid-5th centuries ad and long lasting until the 9th–10th centuries ad was related to economic and cultural factors which led to a phase of land abandonment. Finally, between the 11th and 13th centuries ad, the vegetation cover shifted again towards an open macchia environment at the same time of a re-settlement phase well evidenced also by intensive orcharding. Charcoal data also showed that the expansion of olive and chestnut in central Italy only began in the Late Medieval Period (11th century ad) and not in the Roman Period. This means that extensive cultivation of chestnut and olive has very recent origins and should be attributed to one and the same macro-factor such as the set-up of the economic establishment of the feudal system and the later political organism of the Medieval town.

Cultural landscapes were prominent during the Early Roman period when agronomic knowledge allowed the spread of intensive land exploitation in most of the available land. The aim of this contribution is to explore whether for the Campania region (Southern Italy) archaeoenvironmental data would support continuity or change in the cultural landscape of Roman tradition in the 4th and 5th centuries. To do so, new data from two sites located on the northern slopes of the Vesuvius, both buried by the AD 472 eruption have been investigated. Charcoal analysis, 14 C dating, and chemical analysis of organic residues were carried out in order to study the landscape and the food production at these sites. The results suggest the persistence of the Roman cultural landscape until the 4th and 5th centuries in this area. The landscape is in fact strongly marked both in agriculture and woodland exploitation and management, being characterized by managed chestnut forests as well as valuable cultivations of walnut, large vineyards, olive groves, and probably orchards and crops. The integrated approach with archaeobotanical and archaeometric analyses proves to be a powerful method for the study of the past landscapes, providing a good insight into the environment. Furthermore, this study provided the most ancient evidence of chestnut silviculture for wood.
