Methods of acquisition and use of firewood among hunter-gatherer groups in Patagonia (Argentina) during the Holocene

Abstract

The present article examines the ways of obtaining firewood and of using it by Patagonian hunter-gatherer groups and the relationship with their high mobility. With these goals, we have selected a range of archaeological sites in varied types of vegetation: forest, forest-steppe ecotone and steppe (according to pollen reconstructions and current records) in several different latitudes of Argentinean Patagonia: Paredón Lanfré (Río Negro province); Cerro Pintado (Chubut province); Cerro Casa de Piedra 7 and Orejas de Burro 1 (Santa Cruz province). The taxa, including Nothofagus pumilio, Austrocedrus chilensis, Ribes magellanicum, Embothrium coccineum and Fabiana imbricata, found among the scattered charcoal remains in the sediments of the four Patagonian sites, show how firewood was gathered in types of vegetation similar to the ones that nowadays surround the archaeological sites. The archaeobotanical results allow us to detect differences and similarities of the supply of wood and its relationship with human mobility, site functionality and the types of occupation.
