Abstract

A megafossil wood remnant of Norway spruce (Picea abies (L.) Karst.) was retrieved from a high-elevation nunatak in the southern Swedish Scandes. The site was nearly 600 m higher than the present-day treeline. These circumstances comply with analogous earlier recoveries, indicating presence of spruce at high elevations in the Scandes, several thousands of years prior to inferences made by pollen analysis. Radiocarbon-dating yielded a median age of 9300 cal a BP. This result adds firm detail and adheres to ongoing reappraisal of the structure and biodiversity of the late-glacial and early Holocene mountain landscape, in the light of growing megafossil and molecular genetic evidence.
