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 (p0.05) were observed in some lags. §These results confirm the hypothesis of using§dendrochronological data as a climate signal for§further analysis, such as reconstruction of climate§in the past or prediction in the future for the same§locality.
