Abstract
Trees are the foremost source for producing the oxygen in environment and ensure a healthy productive and sustainable environment. In our campus, we have number of trees with different species. Accurately identifying and managing a large number of trees can be a challenging task. So we have generated QR code for each distinct tree and mapped them with its description like tree id, botanical name, english name, tamil name, family and its medicinal uses. Students and visitor can get details about the tree by scanning the QR code with their smartphone camera which has QR code reader apps. The research findings explores the benefits, challenges, and potential applications of QR codes for tree identification, inventory maintenance, and educational outreach. The findings highlight the potential of QR codes as a valuable tool for enhancing tree management practices and fostering a deeper understanding and appreciation of campus green spaces.
