A high Late Holocene tree‐limit and the establishment of the spruce forest‐limit – a case study in northern Sweden
Radiocarbon dates of subfossil pines found on dry ground above the present‐day tree‐limit are reported from northern Sweden. The uppermost and oldest specimen germinated c. AD 300–600. During some shorter part of this interval the tree‐limit might have been 235 m higher than it was at the turn of th...

Radiocarbon dates of subfossil pines found on dry ground above the present‐day tree‐limit are reported from northern Sweden. The uppermost and oldest specimen germinated c. AD 300–600.

Based on a current adiabatic lapse rate of 0.7°C per 100m, it may be tentatively deduced that the summers were at least 1.6°C warmer. The pine tree‐limit and upper pine populations are inferred to have declined substantially shortly after AD 600. The tree‐limit reached a low at the end of the Little Ice Age.
