Animal mobility is a common strategy to overcome scarcity of food and the related over-grazing of pastures. It is also essential to reduce the inbreeding rate of animal populations, which is known to have a negative impact on fertility and productivity. The present paper shows the geographic range of sheep provisioning in different phases of occupation at the Iron Age site of Turó de la Font de la Canya (7th to 3rd centuries BC). Strontium isotope ratios from 34 archaeological sheep and goat enamel, two archaeological bones and 14 modern tree leaves are presented. The isotopic results suggest that sheep and goats consumed at the site were reared locally (within a few kilometres radius) during the whole period of occupation. The paper discusses the isotopic results in light of the socio-political structure of this period, as complex, strongly territorial societies developed during the Iron Age in the north-east Iberian Peninsula. This paper was developed as part of the research projects ‘The origins of intensive pastoralism and the creation of cultural landscapes in North-Eastern Spain (HumanScapes)’, which was funded by the European Commission with a Marie Curie Intra-European Fellowship (grant number 330098) and the Service of Archaeology and Palaeontology of the Culture Department of the Catalan Autonomous Government under the direction of HAO and PH, and the ERC-Starting Grant 716298 ZooMWest- Zooarchaeology and Mobility in the Western Mediterranean: Husbandry production from the Late Bronze Age to the Late Antiquity, funded by the European Research Council Agency (ERCEA) under the direction of SVL. The research also benefited from the support of the Agència de Gestió d’Ajuts Universitaris i de Recerca (2017SGR995).

The MadriuePerafitaeClaror valleys (MPCV) (Eastern Pyrenees, Andorra) were the focus of a multidisciplinary microregional landscape research project that aimed to study the long term shaping of this UNESCO World Heritage Site in the category of cultural landscape. The study area is situated on a glacial modelled high mountain environment ranging from 1250 to 2800 m.a.s.l. Multidisciplinary approaches integrating archaeology and palaeoenvironment have been directed towards the unravelling of the long-term humanelandscape relationships, which ultimately resulted in the MPCV cultural landscape. The development of high-resolution temporal and spatial studies could successfully correlate archaeological and palaeoenvironmental data. This study leads to the location of more than 400 archaeological structures, 55 of which were excavated, and the multiproxy study of 7 palaeoenvironmental sequences. The combination and analysis of all these data have permitted developing a history of human-environment interactions fromthe Mesolithic to the 20th century. In this paper, data gathered in the MPCV corresponding to the Neolithic and Chalcolithic periods are presented for the first time. During the Early Neolithic small groups are documented with a diversified economy in which grazing, hunting, fishing, gathering and an incipient cereal agriculture activities are well represented. These groups seem to follow highly mobile occupation patterns with continuous high mountain seasonal grazing exploitations that lasted one or two centuries. They appear to frequent diverse altitudinal belts in order to take advantage of different resources. A strong pastoral orientation is related to the exploitation of high mountain areas. During the Middle/late Neolithic human groups show a higher degree of sedentism. Hunting and gathering are still important activities although agriculture and animal husbandry increase in importance. During this period an augmentation in the pastoral pressure in the MPCV is also documented, linked to the first use of fires to create grazing areas. Symbolic landscape appropriation practices are also firstly documented during this period. During the Chalcolithic, human landscape use becomes intensive enough to cause permanent landscape changes. The upper parts of the MPCV are deforested by the action of fire while intensive agriculture takes place at the lower valleys. The evidence presented by the MPCV project demonstrates that it was during the Neolithic when this high mountain cultural landscape was firstly formed. This process is probably related to an increase in the population and progressive sedentism, which required a more intensive and organised use of resources and, eventually, the adoption of landscape management practices.
