Pulau Payung which located in Musi Estuary, the longest river in Sumatera, hosts a dense mangrove cover in South Sumatera, Indonesia. Mangrove is known to be a highly productive ecosystem and has many functions ecologically. However, human pressure around this area and increasing demand for land represent increasing threats to mangrove. The aims of this research were to investigate the changing of mangrove coverage in 2009 – 2019. In the present study, the mangrove coverage together with species composition was evaluated through remote sensing (Landsat-8) and ground-truth (Transect Quadrat Method) observations. The results showed that the major mangrove composition dominated by 4 genera,  Avicennia, Sonneratia, Rhizopora, and Nypa. The mangrove coverage decreased slightly from 497.65 ha in 2009 became 488.49 ha in 2019.
