The radial growth dynamics of Scots pine in a large raised bog located in the territory of the Volga-Kama Nature Reserve, Republic of Tatarstan, has been studied. The master chronology correlated positively with the total amount of precipitation in January and negatively with the mean monthly temperature in June. Based on a complex analysis of temperature and precipitation in different months using hierarchical regression trees, three scenarios resulting in increased, average, and decreased radial growth have been suggested.
