Trees are a great bank of data, named sometimes as the "silent witnesses" of the past. Due to annual formation of rings, which is normally influenced directly by of climate parameters (generally changes in temperature and moisture or precipitation) and other environmental factors. Using dendrochronological methods for obtaining samples of Pinus Nigra from the Catalonian PrePirineous region with total time spine of about 100 - 250 years were analyzed for the tree ring width (TRW) patterns and had quite high correlation between them (0.71 - 0.84), corresponding to a common behaviour for the environmental changes in their annual growth. Analyzing the cross-correlations between obtained tree ring width indexes and climate data, significant correlations (p
Trees are a great bank of data, named sometimes asthe "silent witnesses" of the past.

Using dendrochronological methods for obtainingsamples of Pinus Nigra from the CatalonianPrePirineous region with total time spine of about100 - 250 years were analyzed for the tree ring width(TRW) patterns and had quite high correlation betweenthem (0.71 - 0.84), corresponding to a commonbehaviour for the environmental changes in theirannual growth. Analyzing the cross-correlations between obtainedtree ring width indexes and climate data, significantcorrelations (p<0.05) were observed in some lags. These results confirm the hypothesis of usingdendrochronological data as a climate signal forfurther analysis, such as reconstruction of climatein the past or prediction in the future for the samelocality.
