Abstract

Introduction: CLIMATE change happens due to abnormal changes of CLIMATE within the earth’s atmosphere and their consequences. One of the most significant effects of CLIMATE change is the irreversible damage to some floral species and forest ecosystems. Tree species reflect the impact of CLIMATE changes on their ring width. Generally, tree rings vary in size each year depending upon the environmental conditions or CLIMATE variables that the tree experiences. In fact, tree rings are severely dependent on the changes of CLIMATE variables. It is considered a basis for “dendrochronology” which is the scientific method of dating based on the analysis of patterns of tree rings or investigation of CLIMATE variables effects on tree ring width. Many national and international studies have been conducted on dendrochronology. However, the national researches investigated the effects of temperature and rainfall changes on RADIAL GROWTH of trees. Unfortunately, due to lack of long-term SOLAR RADIATION data in the most of meteorological stations in Iran, the effect of this parameter on the RADIAL GROWTH of trees has not been studied so far. Meanwhile the SOLAR RADIATION has a significant effect on the width of tree rings-especially in tolerant shaded species like oak. One of the most important species of trees in Iran is the Oak tree (Quercus castaneifolia), due to its being spread in different areas of the country and its high economic and environmental value. Unfortunately, in recent years, because of CLIMATE changes and droughts, and also overcutting of Quercus castaneifolia for wood and live-stokes food supply, this precious species has been subjected to serious threats. In this regard, the role of CLIMATE in addition to improper management is significant. To protect Quercus castaneifolia, the first and most important step is the scientific planning of forest management, through knowing the effective parameters of CLIMATE change on the growth and physiology of the trees. Therefore, implementation of more research on the oak species and utilizing the results is essential for their protection.
