A remarkable scientific discovery has revealed that a Banyan tree (Ficus benghalensis) in Munger, Bihar, is approximately 700 years old, making it the world’s oldest accurately dated banyan tree. Unlike earlier estimates based on folklore or historical records, researchers from the Birbal Sahni Institute of Palaeosciences (BSIP) used Accelerator Mass Spectrometry (AMS) radiocarbon dating to determine the tree’s age with scientific precision. This breakthrough not only rewrites the historical timeline of the region but also establishes a reliable method for dating tropical heritage trees that lack annual growth rings.
This article provides a comprehensive overview of the 700-year-old Munger Banyan, explaining the scientific dating process, radiocarbon analysis, Accelerator Mass Spectrometry (AMS), the role of the Department of Science and Technology (DST), historical significance, biodiversity value, conservation implications, and the importance of preserving India’s natural heritage. It also explores how this innovative methodology can help accurately determine the age of ancient tropical trees worldwide, benefiting heritage conservation, climate research, biodiversity studies, and environmental management. Whether you are preparing for UPSC, State PCS, UGC-NET, Forestry, Environmental Science, Geography, or Current Affairs, this guide offers a fascinating insight into one of India’s most significant recent scientific discoveries.
