Holocene vegetation and climate dynamics of the boreal alpine ecotone of northwestern Fennoscandia
Abstract Climate change with respect to summer temperature throughout the Holocene is inferred from oscillations in the local Pinus sylvestris , Alnus incana and Betula pubescens forest‐lines, as recorded by fossil pollen and plant macrofossils in lake sediments at four altitudinal levels.

Abstract Climate change with respect to summer temperature throughout the Holocene is inferred from oscillations in the local Pinus sylvestris , Alnus incana and Betula pubescens forest‐lines, as recorded by fossil pollen and plant macrofossils in lake sediments at four altitudinal levels. Mt Skrubben (848 m a.s.l.), in Dividalen, was deglaciated down to below 280 m a.s.l. during 10 800–10 300 cal. yr BP. Betula pubescens established 10100 cal. yr BP at 280 m a.s.l. and expanded up to near the summit during the next 700 years. Birch woodland prevailed on the mountain plateau until 3300 cal. yr BP. Local Pinus sylvestris stands are recorded up to 400 m a.s.l. at 8450 cal. yr BP and >548 m a.s.l. about 8160 cal. yr BP.
