Radial Increment of Pinus sylvestris L. in the Insular Pine Forests of Northern Kazakhstan in the Context of Climate and Geomorphological Conditions

Tree-ring chronologies based on the annual ring width of Scots pine (Pinus sylvestris L.) have been studied at eight test sites in insular pine forests in the north of the Republic of Kazakhstan from the Turgay Depression to the eastern part of the Kazakh Uplands. Analysis of the relationships between radial increment of pine and climate shows that the climatic signal in the chronologies can change depending on geomorphological conditions caused by the edaphic factor, relief, and absolute elevation marks. These features must be taken into account when using tree-ring chronologies for spatiotemporal reconstructions of climate.
