In the Eastern Massif Central, new research programs are dealing with the landscape evolution since the Late Glacial and during the Holocene (AGES and WRACC projects). In this context, a reconstruction of climatically and anthropogenically driven palaeoenvironments is in progress for the last 7,000 years. This palaeoenvironmental study of peatlands and archaeological remains focuses on an area still poorly documented: the Mezenc massif and the Ardèche mountain range, and particularly on the Béage volcanic plateau (Eastern Velay, Massif Central). The plant macrofossil analyses of a 5.5 meters long core, from the La Narce peatland on the Béage plateau (1,235 meters a.s.l.), revealed an excellent preservation of organic matter so to allow high-resolution reconstruction of environmental change. The La Narce peatland is located in a little catchment area (0.13 squared kilometres), at the interface between basaltic lava flows and the Velay granitic substratum. The sedimentary sequence is composed by a succession of sandy lacustrine clays (from basal levels to 4.4 m), organic lacustrine deposits such as gyttja (from 4.4 to 2.5 m) and peat (from 2.5 m to the current surface). Two radiocarbon dates (14C) indicate a deposition of sediments since the end of the Late Glacial period. Plant macrofossil remains, small charcoal particles (<2 mm), magnetic susceptibility peaks and archaeological remains from the near surroundings (handmade granitic-tempered ware and shards of flint) suggest a first human impact during the Early Neolithic period, close to 4,900 cal. B.C. The outcome of this high resolution study will allow clarification and absolute dating of this early anthropogenic impact (and of later pastoral and agricultural activities), which in turn will be compared to the palaeoecological analyses of other regionally important sites (e.g. nearby Pialeloup raised bog) in order to complete our vision of environmental changes during prehistorical and historical times.
