Identifying evidence for hunter-gatherers in the palaeoenvironmental record is far from simple. Despite decades of research, few studies have demonstrated unambiguous palynological evidence of hunter-gatherers. This paper presents the results of high-resolution palaeoecological analyses of a peat sequence located within the vicinity of the pre-historic Yup’ik village of Nunalleq in southwestern Alaska. The aim of this research was to examine whether there are any discernible palaeoenvironmental impacts associated with the 15th–17th century occupation of the site. Presuming an ephemeral character to any palaeoecological signal, this study selected a sampling location approximately 30 m east of the limit of archaeological remains. Pollen, non-pollen palynomorphs and microscopic charcoal analysis were then used to generate a highly resolved (contiguous 1 cm) environmental history for the site. The results are striking and indicate that the activities of prehistoric Yup’ik hunter-gatherers at Nunalleq did leave a clear material trace in the palaeoenvironmental record. Through the application of high-resolution Pb210 and C14 dating and Bayesian modelling, these impacts were found to be concurrent with the occupation of the archaeological site. These findings suggest that not only can circumpolar hunter-gatherers leave a material palaeoenvironmental trace but that these traces may be used to accurately date such site activity in lieu of excavation.

Palynological research is increasingly revealing the landscape impacts of Norse colonisation in southern Greenland. Typically, although not exclusively, these studies are from depositional environments with highly localised pollen source areas close to fjord-side centres of medieval power. In contrast, this paper presents data from Vatnahverfi, an inland district of the Eastern Settlement, and explores the emergence of a cultural landscape through three pollen sequences at variable distances from Norse farms. Two are from mires with small pollen source areas close to (<100m) and distant from (=1500m) probable farming activities. The other provides a more regional signal of vegetation change, albeit one located close to a Norse settlement. Landnám is marked primarily through an increase in microscopic charcoal and the appearance of pollen from Rumex acetosella, although significant differences between profiles are noted. Close to Norse ruins, pollen productivity from grassland communities increases and woodland and scrub representation declines. Further from archaeological remains, palynologically inferred human activity is primarily characterised by decreased productivity, notably declining influx from woodland and scrub species, reflecting grazing herbivores or coppicing. Abandonment of Vatnahverfi is indicated from the late 14th to early 15th century AD. [ABSTRACT FROM AUTHOR]

Transhumance agriculture formed a key component of subsistence strategies in the Norse economies of the North Atlantic, with evidence of shielings or sæters found in Norway, Scotland, the Faroe Islands and Iceland. It is frequently assumed to have played a role in Norse Greenland, yet little enquiry has been made into such activity. This paper seeks to address this deficit, presenting the first palaeoenvironmental study of a suspected Greenlandic shieling site in the uplands of the former Norse Eastern Settlement. Pollen analysis, 14C and associated proxies are used to date and assess the environmental and landscape impact of shieling activity. Evidence for vegetation disturbance associated with Norse settlement is indicated from c. ad 985, but the shieling itself is interpreted as having been established somewhat later (cal. ad 1050–1150). Initially the site appears to have been used exclusively for grazing of livestock and there is tentative evidence for the use of burning to stimulate the spread of pastures. Pollen influx figures suggest the intensification, or initiation, of hay production c. cal. 1225–1325 reflecting either the spread of settlement from the lowland valleys, or evolution of the site into a full farm in response to population pressure. A reduction of human impact cal. ad 1300–1390 suggests a reversion to shieling activity, indicating similarities to transhumance in northern Iceland. Abandonment of the site dates to cal. ad 1325–1415 and is in agreement with previous evidence from Norse Greenland. [ABSTRACT FROM AUTHOR]
