This paper focuses on early Holocene tree growth and alpine tree-limits in the northernmost Swedish Scandes. Megafossil wood remnants in peats and lakes were searched for over a large area at elevations high above the modern tree-limits. The results

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
A decade of tree-line monitoring in the southern Swedish Scandes in Climatological extremes in the mountains, Physical background, geomorphological and ecological consequences.
Results from long-term tree-line monitoring, based on repeat photography from fixed photopoints, are presented. The tree-line studied is a broad ecotone with sparse and mixed populations of Betula pubescens ssp. tortuosa, Picea abies and Pinus

Subfossil pine (Pinus sylvestris L.) occurs in various deposits and in great freqency well above the current altitudinal pine limit in the Scandes Mountains. These tree remnants constitute a fairly continuous record of range-limit dynamics
