Seagrass is the only plant that can live in shallow waters, and in groups with the same species (monospecies), as well as with different species (heterospecies), and form a seagrass bed. Seagrass beds have an important ecological role, one of them as a carbon storage in shallow water. Seagrasses can store carbon in the form of biomass from its body. Seagrass beds can be found on Talango Island, Sumenep, Madura. Exploration of seagrass beds in this location has not been carried out, especially related to its potential in storing carbon. The aim of this study was to find out the important value index of seagrass species and to estimate their biomass. This research was conducted from October to November 2016 at two stations on Talango Island, Sumenep, Madura, using the Point Intercept Transect (PIT) method. The data taken during the research comprise the species diversity, density, covering and frequency of seagrass. Data analysis was performed to obtain the important value index and to estimate the biomass of seagrass species. The results show that Enhalus acoroides have the highest important value index. Furthermore, the highest biomass estimation value is obtained from Enhalus acoroides, which is 1,650 gram/Ha. Moreover, the total estimation of the seagrass bed on Talango Island is 1,721.250 gram/Ha. © 2017 Author(s).
