Dendrochronological techniques were used to investigate the influence of climatic factors on the radialgrowth of Scots pine (Pinus sylvestris L.) under theimpact of dust pollution in the industrial region of NortheastEstonia. Study sites Narva-1 and Narva-2 suffer dust pollutionstress from oil shale fired power plants located in thisregion. The impact of climate on radial growth of pines atthree study sites was modelled using response functionanalysis. Tree-ring indices chronologies for each study sitewere compared using regionally averaged temperature andprecipitation data sets for the period 1946–1991. Amongtemperature variables significant predictors of radial growthalong with the temperature of winter months, generallylimiting the growth of pines in this region, are midsummertemperatures of the current year and temperatures of theprevious growth season. For each site a different set ofprecipitation variables limiting growth was detected. Only anoptimum amount of precipitation during the previous summer hasa positive effect on radial growth on all sites. An increasedimportance of precipitation to the radial growth in dust-polluted sites was detected.
