Plant economy of a seasonally occupied site at high altitude during the Neolithic / Lucie Martin
Plant economy of a seasonally occupied site at high altitude during the Neolithic : the Rockshelter of l'Aulp du Seuil in the Chartreuse Massif (Saint-Bernard du Touvet, Isère, France) . MARTIN Lucie. In "Construction des territoires montagnards", 2ème International Workshop on archaeology of european mountain landscape, organisé par les laboratoires GEODE, FRAMESPA, GEOLAB et Chrono-Environnement. Université Toulouse 2-Le Mirail, 8-11 octobre 2009. [Première journée].
The site of l’Aulp du Seuil is located on the eastern border of the Chartreuse Massif at an altitude 1727 meters. The site, at the bottom of a small valley dug into an urgonian perched syncline, is isolated and difficult of access. At present a subalpine mountain pine forest, associated with pastured grasslands and subalpine heaths occupy the surroundings of the site. Numerous blocks were deposited during the last glaciation. They were used as shelters and seasonal hunting camps since the Mesolithic. Especially animals like chamois, alpine ibex, red deer or wild boar were hunted.
Recent excavations directed by David Pelletier (2004-2005) in the block-shelter “ALP 1” uncovered several occupations from the Mesolithic to historic periods. The present study focuses on the archaeobotanical analyses (charcoals and other plant remains) of one level dated to the middle Neolithic and including several earths. The results permit to evoke the plant economy of these human groups.
In this presentation, we will approach questions like :
- How did they manage fuel-wood ?
- How did they use wild local plants ?
- What was the consumption, on the site, of gathered and domesticated plants ?
Results highlight the mobility of Neolithic people, their knowledge of environmental setting and their capability to exploit the resources of mountain environment.
