The presence and diversity of Gastropods is largely determined by their habitat conditions. The mangrove ecosystem in Lambur Village is currently experiencing environmental degradation. This research aims to find out the diversity of species of Gastropods and know the characteristics of Gastropod’s habitat seen from physical and chemical factor of invironment in the mangrove ecosystem of Lambur Village Tanjung Jabung Timur Regency. This research is descriptive explorative, with station determination using purposive sampling. The study sites were divided into three research stations. Gastropods located on the surface of the substrate and attached to the root of the mangrove plant are taken manually by hand collection technique, while the gastropod located inside the substrate is dug collection technique using a shovel. Environmental parameters measured include substrate type, temperature, pH, and salinity. The results obtained were analyzed using index of species diversity and dominance index. Gastropods were found to total 539 individuals including 21 species of 15 genera, which belong to 8 families. The index of the diversity of the three stations was categorized by medium with respectively values of 2,461, 1,893, and 2,533, while the dominant index of the three stations was categorized as low with respectively values of 0.106, 0.201, and 0.096.
