Dendrochronology is the scientific method of determining the age and studying the history of trees by examining their annual growth rings. The word is derived from three Greek words: “dendron” meaning tree, “chronos” meaning time, and “logos” meaning study. It is commonly known as tree-ring dating. Dendrochronology is an important technique in environmental studies, archaeology, palaeoecology and Physical/Biological Anthropology because tree rings preserve information about past environmental and climatic conditions. Most trees in temperate and some other regions produce a new growth ring every year. During favourable growing conditions, especially in spring and early summer, trees generally produce lighter and wider wood called earlywood. Later in the growing season, growth becomes slower and produces darker and
