A boreal-temperate transect in Europe: history of pine stands reconstructed from the radial growth of trees

100%

Parn H.

nr 4

History of the Scots pine sites along the Finland-Poland boreal-temperate transect along 25°E longitude, ranging from 50°N-70°N latitude (see Fig. 1 in Breymeyer 2003) was reconstructed using tree-rings. The correlation between the tree-ring index chronologies for the sites was studied. The age of trees at particular sites varies in the range from 66 to 178 years. The youngest trees are growing at the sites FN3 and PL3, the eldest at FN1. At the sites FN1 and PL1, two groups of trees of different age were separated. Correlation analysis revealed significant correlation among the Baltic chronologies. High correlation coefficients were also found between the PL2 site chronology and all the Baltic state chronologies. No positive correlation was detected among the chronologies from the sites in Finland and in Poland.
