River valleys in the Tien Shan Mountains of Kyrgyzstan have served as corridors for human dispersal since the Palaeolithic but little information exists on the history of human occupation in this remote and inaccessible region. Here, we report the results of a multidisciplinary study of Airgyrzhal-2, a high elevation (2005 m) site in the Naryn valley in central Kyrgyzstan. Two main occupation horizons were recognized, the earliest belonging to the Mesolithic (12th millennium cal. BC) and a later one dating from the Bronze Age (first half of the 2nd millennium cal. BC). Land snail analyses from the two horizons yielded almost identical assemblages of species of dry, open environments. Archaeobotanical data, however, revealed marked differences. The greater representation of willow/poplar ( Salix/Populus ) in the charcoal from the Mesolithic suggests more focused activity along the river, which might have been closer to the site at this time. The occurrence of spruce ( Picea ) and other species in the Bronze Age charcoal indicates exploitation of resources from more distant upland locations. The occurrence of the remains of cereals, including both grains and chaff, provides unexpected evidence for both consumption and cultivation of wheat and barley at this high elevation during the Bronze Age.

This paper focuses on the web of relationships established between Early and Middle Bronze Age communities and their environment in Northwest Iberia. Charcoal remains recovered from settlements and funerary sites in this area can inform a greater understanding of wood resource procurement and woodland management strategies adopted by these small-scale communities. Although charcoal analysis of contexts with chronologies ranging from 2200 to 1200 cal. BC is not commonly undertaken in this area, data from this period are of great importance because it represents a phase of major deforestation and landscape change. Wood resources were local and exploitation was conditioned by their availability in the environs of the sites. These communities established a clear preference for Quercus wood, combined recurrently with shrubby species of the Fabaceae family. This co-occurrence, previously observed in Middle and Late Bronze Age contexts, could extend back to the Early Bronze Age and even to the Late Neolithic. The presence of small trees and shrubs such as Rosaceae/Maloideae and Corylus avellana could be related with the open landscape that characterises this period, and with the existence of woodland management practices designed to prevent forest regeneration.
