Afriyani et al, 2017. Vegetation Diversity of Mangrove Forest in Payung island Sungsang Village Banyuasin District. JLSO 6(2):113-119.The mangrove forest is a natural biological resources with various diversity potential that provides benefits directly or indirectly for the life of living beings.

Important Value index (IVI) is a diversity index and parameter analysis of mangrove vegetation. There are 4 species of mangrove was founded in 3 transect observations, namely Avicennia alba, Avicennia marina, Bruguera apicullata gymnorhiza and Rhizophora.
