Val Febbraro-Valle Spluga : a survey of the use of an upper mountain-alpine area in Central Italian Alps. Dagfinn MOE. In 2eme workshop d'Archéologie du paysage des montagnes européennes "La construction des territoires montagnards : exploitation des ressources et mobilité des pratiques" organisé par les Laboratoires GEODE et TRACES (Toulouse) et le Centre d'Archéologie Préhistorique du Rhône aux Alpes (Valence, France). Université Toulouse II-Le Mirail, 8-11 octobre 2009. [Première journée.]
An interdisciplinary palaeoecological study in the low-alpine and subalpine zones of Val Febbraro, upper Valle di Spluga in Italian central Alps, between 1830 and 2304 m a.s.l., suggests the temporary presence of early Neolithic groups at about 6000 uncal b.p. Evidence for local woodland clearance and charcoal dust were found. Phases of woodland and treeline disturbances, and indications of increased human presence are evident at about 5500, 5100, and 4000 b.p. A marked increase in disturbance, mainly related to pasturing, is dated to the beginning of the Bronze Age.
The last major stage of human impact on the vegetation coincides with the Final Bronze phase and the beginning of the Iron Age, with a small temporary reduction during the Roman period. 14C dated archaeological sites and finds are broadly concordant with the phases of human impact on the vegetation. The former use of a present day tourist path using the Baldiscio Pass between Valle Febbraro (I) and Valle Mesolcina (CH), is dated back to between 3500 b.p. and 3000 b.p.
A summary figure is presented. No locally significant climatic changes have been traced during the last 6000 years, and if present, they are probably overshadowed by the vegetational changes caused by human activity.
