| description | A variety of gastropod species can be found in the mangrove ecosystem. The presence of gastropod is critical to the mangrove ecosystem's long-term viability. This study is aimed to determine the abundance of gastropods in the replanted mangrove forests along the Kerteh River, Terengganu. A total of 1,676 gastropod individuals, representing 9 species and 6 families, were observed at 2 study sites. A transect line of 30 m was laid out at each area of the sampling sites. In each transect line, quadrats (1 × 1 m) were laid at 10 m intervals and the distance between each transect line was 20 m. The results from this study showed a significantly higher diversity in a 5 year replanted forest than in a 10 year replanted forest by using the t test=2.968 (p |

In term of species composition, Pirenella cingulata and Optediceros brevicula were the dominant species at both sites.
