Annual ring analysis of persian oak (Quercus Brantii) to determine periods of stress and tensions on Zagros Forests (case study: forests of Ilam County)
Abstract
Goal of this study was to analyze relationships between the annual variability of Persian Oak (Quercus Brantii) tree-ring chronologies and the variability of the main climatic parameters in Zagros forests of Iran. In order to conduct this research, 17 annual ring diskettes of 17 Persian Oak tree collars, in CheghaSabz District of Ilam County, were collected and transferred to laboratory. The measurements of the cores were made with the LINTAB device and TSAP program. Growth status analysis and dendrochronology results indicated that since 2001, growth rate has declined and on the other hand, reduced rate of annual rainfall, temperature rise and increased dust, considering that the area is prone to such factors, have imposed stress in species of Persian Oak. General conclusion drawn is that dominant situation on the study regions, increases the sensitivity of the area towards start of stress and drying and considering changes in climate features and high rate of human activities, reduced growth and consequently start oak wilt and decay and the process is completed by the activity of secondary pests.
