Monitoring the success of plant growth after forest and land rehabilitation is essential to ensure the effectiveness of environmental restoration efforts. This case study evaluates the use of manned unmanned aerial vehicles (UAVs) in monitoring crop growth in Barru District. This research was carried out in the forest and land rehabilitation areas of the Lisu, Segeri, and Pangakajene river basins. The data analysis used is calculating the number of trees using the object base image analysis (OBIA) method, and calculating plant height using canopy height model (CHM) analysis. Next, the growth percentage is calculated to evaluate plant growth resulting from forest and land rehabilitation planting activities. The analysis using the OBIA method revealed that 19,811 plants were in the Allu block, 11,983 plants were in the Bonto Payung block, and 11,927 plants were in the Landange block. In addition, for canopy height model (CHM) analysis, plant height varies from 0 – 1 meter, 2 – 3 meters, and > 3 meters. The research results show that using UAVs increases the accuracy and speed of monitoring and can identify areas that require additional intervention. These findings emphasize the importance of integrating UAV technology into environmental rehabilitation programs to achieve long-term sustainability.
