Subfossils of Scots pine (Pinus sylvestris L.) from the mountain area of South Norway as the basis for a long tree-ring chronology

Abstract

In order to use the South Norwegian alpine pine subfossils as the basis for dendroclimatological purposes, information about samples collected earlier is presented. The potential to construct a complete Holocene tree-ring series in this area based on pine subfossils is good. The construction of floating chronologies from the early Holocene period should be easier to achieve than chronologies from later periods. The maximum level and the changes in the Holocene pine forest level are different in the three zones defined in this paper. The gap 6400 - 6000 calendar yrs. BC represents a period of decreased temperature. The gap 3100-1500 calendar yrs. BC is well known for it's changing enviroment (probably climactic changes).
