Efforts to manage mixed deciduous forests around the world have the potential to contribute to global sustainability significantly. This study focuses on the carbon stock assessment, comparing the GLOBE-based method with the Drone-based method in managing mixed deciduous forests in Krabi province, Thailand. Field data were gathered from a 40x40 m2 two-sample plot within the Krabi province's mixed deciduous forests, and the carbon stock of standing trees was determined using allometric equations. The drone-based technique for estimating tree height was compared with the GLOBE-based method. Results revealed an average carbon storage of 6604.73 kg and 6181.39 kg for the drone-based and GLOBE-based methods, respectively in site 1 (Wat Kaew Korawaram), and an average carbon storage of 12817.87 kg and 10342.04 kg for the drone-based and GLOBE-based methods in site 2 (Thara Park). The notable difference in carbon storage estimates between the techniques may be attributed to potential human errors, including inaccuracies in measuring the diameter at breast height (DBH) and variations in the steps taken by different individuals. Future projects will involve planning adjustments to the measurement methods to enhance precision and reliability. Nonetheless, it can be inferred that managing mixed deciduous forests in Krabi province shows promise in climate change mitigation. This aligns with broader objectives such as addressing climate change, promoting sustainable land management, conserving biodiversity, supporting carbon trading initiatives, formulating legislation, advancing research, and educating the public on the significance of maintaining healthy ecosystems.
