ABSTRACT

The results of analysis of tree-ring growth for Scots pine from islands of Ketersky archipelago in The White Sea, Russia are presented. Two tendencies were found for pine radial growth: a positive response to spring warming and a negative one to the increase of winter precipitation. The link between radial growth and climatic variables changes over time, which is due to regional climatic shifts. The complex impact of climatic factors on radial growth was evaluated through decision trees (CART). This integrated approach allowed to propose three scenarios leading to increased, moderate and lowered radial growth. The detected relationships can be used in further investigations of three growth and adaptations in relation to the climate change.
