 This study used ALOS-2-Palsar-Elban-Dualpore, HH and HV, Synthetic Aperture Radar, SAR, images to estimate above-ground biomass, AGB, of Shasham tree species in the managed forest of Chichawatni Irrigated Plantation, Siwall District, Punjab, Pakistan. The study found that non-linear regression models between field-based AGB and SAR backscatter sigma-naught values have R2, 0.47 and 0.55, and RMS-E, 1.18 and 1.87, values for HH and HV-PAL data, respectively. The validation R2 values are small, however, outliers are identifiable in the validation scatter plots. The AGB map generated from this study provide a first estimate of AGB values from remote sensing in the study region, especially in the context of the RED-PLUS program.
