Abstract

In this study, using dendroclimatology (a branch of the science of dendrochronology), the impact of climate variables on normal and DECLINEd oak stands was studied near the city of “Khorram Abad”, Iran. After the selection of 12 samples from healthy trees and 12 trees from DECLINEd ones, breast height (1.30 m) discs were prepared. Then, the samples were scanned and RING WIDTH was measured using Corel Draw software. Using TSAP and ARSTAN softwares, cross dating between samples were done and chronology was prepared, respectively. From the nearest meteorological station, rainfall and TEMPERATURE data were obtained and their effects on growth rings of trees was investigated using Pearson's correlation coefficient. The results of this study showed that both chronologies were equally affected by climatic factors. The TEMPERATURE during the growing season and before it had a similar effect on both chronologies. Until 2010, the growth of trees was almost the same, but from this year onwards, curve of DECLINEd trees dropped in growth, probably due to the impact of pests and the deterioration in trees. From this year onwards, despite the significant increase in PRECIPITATION, compared with previous years, increasing growth of the DECLINEd trees was not found and this means that due to the factors causing deterioration and thus reducing the activity of cambium, the trees have lost their re-growth and even with the improvement of environmental conditions, there was no possibility of growth resumption.
