Tree-limit landscape evolution at the southern fringe of the Swedish Scandes (Dalarna province) - Holocene and 20th century perspectives

Auteur :
KULLMAN, L.

Description :
The long-term history relies mainly on radiocarbon-dated megafossil tree remains preserved in peat and mineral soil. The more recent perspective was analysed from age distributions in the most marginal, extant tree populations. Results about Holocene and Modern tree-limit evolution are presented : species-limit positions (Pinus sylvestris, Picea abies, Betula pubescens) at 4 study sites in 1915, 1975, 2003. Thus, 20th century warming and associated biological consequences in the study area fit an extra-regional pattern that is beyond the range of expected late-Holocene natural variability in the study region.
