Tree ring analysis of Larix griffithiana from the Eastern Himalayas in thereconstruction of past temperature

Tree ring analysis of Larix griffithiana (Lindl, et Gord.) Hort ex Carr., a subalpine deciduous conifer growing in Sange, Arunachal Pradesh, Eastern H imalaya has been taken up to understand past climatic changes of this regio n. Rings in this tree have been found very distinct, with clear demarcation of early wood and late wood cells and have characters suitable for dendroc limatic studies. Analysis of tree growth and records of climatic parameters suggest that May temperature is the most important factor in controlling g rowth of this tree. Reconstruction of May temperature using ring width data of this tree has been done.
