From analyzing data on root collar diameter, height, diameter at breast height (DBH)of the trees, along with weather data using Python programming to process data from the Terra satellite in the Google Earth Engine database we found that different tree species have varying growth rates and carbon sequestration capacities depending on their physiological characteristics. These can be categorized into 3 groups: 1. Fast-growing plants with maximum carbon sequestration rates at 5 years old include Erythrina Subumbrans. 2. Trees that reach peak carbon sequestration between 6-20 years old include Castanopsis calathiformis, Spondias axillaris, Alseodaphne andersonii, and Alseodaphne andersonii.
3. Trees with maximum carbon sequestration when older than 20 years include Alseodaphne andersonii, Ficus altissima, and Prunus cerasoides.
Rainfall quantity is another important variable. Therefore, to restore forests to a fully functional ecosystem and efficient carbon dioxide sink, it is necessary not only to select tree species suitable for the area and climate but also to appropriately sequence the planting of seedlings in the area. This is another approach to develop forests into efficient carbon dioxide sinks.
