Vietnam’s tree cover is low compared to the global average. For this reason, the government launched the "Plant 1 Billion Trees for Vietnam" program in 2021. As the number of trees grows rapidly in the future, proper management will be required. Aside from the care of trees provided by tree management departments, the public’s cooperation is essential for trees to grow healthily. This thesis proposes an embedded system and application software for tree management that makes use of QR codes. Each QR code will be used as a tag for tagging trees and can be scanned by anyone to learn more about the trees. This system allows tree management de- partments to easily collect tree data and store it in a cloud database, which can then be retrieved to serve good management and raise community awareness of the benefi t of tree cover among citizens. Experiments on many trees at two pagodas in Soc Trang, a province in the South of Vietnam, were used to calibrate the performance and assess the feasibility of the proposed system.
