DENDROCLIMATIC DIAGNOSTICS OF PINE AND SPRUCE GROWTH IN THE KIVACH RESERVE (RUSSIAN KARELIA)D.E. Rumyantsev
The results of the correlation analysis of Norway spruce and Scots pine growth at the conditions of the Kivach Reserve are discussed in the article. High summer temperatures of the previous season have negative effect on Norway spruce radial growth. High amounts of February precipitation are negative for spruce growth too. The effect of climatic impact on pine radial growth is different for different sites. A positive reaction for the above-mentioned average amounts of June precipitation is a specific feature of chronologies from dry growing sites of pine trees. A significant positive correlation with February precipitation is typical for chronologies from semi-wet sites. Chronologies from bogs (except bogs from lakesides) negatively correlate with November precipitation of the previous calendar year. The negative effect of high December temperatures is significant for most sample areas from different pine growing sites.
