This paper aims to provide a method in mapping the vegetation cover of Acacia mangium plantation using the advanced survey technology of satellite remote sensing. This method would serve as an alternative to the conventional field sampling which is laborious and time consuming. Satellite images obtained from Landsat 8, provide the current view on vegetation cover of the whole plantation area. Two areas were targeted for the study which was area with A. mangium stands aged below 5 years old and another aged above 5 years old. Image analyses performed on Landsat 8 satellite image showed that vegetation coverage in area over 5 years old stands were significantly denser compared to within 5 years old stands. Low solar radiation (reflectance) was detected on area with high vegetation cover while higher radiation was detected on lesser vegetation cover. Overall findings of the study shows that the older A. mangium stand age greatly decreased the transmittance and reflectance of solar radiation in the visible light spectrum due to the increase in biomass. Hence, biomass played a key factor in distinguishing the vegetation covers between the two age classes (below 5 years old and above 5 years old).
