Dendroclimatic Investigations of Pinus Sylvestris L. on Keretsky Archipelago Islands, the White Sea

Abstract

The radial growth dynamics of Pinus sylvestris from different habitats of Keretsky archipelago, the White Sea, was analyzed. Two tree-ring chronologies for dry pine forest and the third one for swamp habitat were built. A positive link of radial growth and climatic factors of winter and spring period was detected. It was shown that relationship of radial growth with climate varies in time. This fact probably is related with winter precipitation increase during last decades detected by weather station, which could alter time of grow process initiation.
