The Tangerang Regency has persistently engaged in the restoration of its coastal ecosystems, particularly focusing on the rehabilitation of mangrove areas previously converted into ponds or abandoned. Mangrove ecosystems serve a crucial role as habitats for various biota, including macrozoobenthos. The reforestation of mangroves serves as a vital measure to uphold the equilibrium of aquatic ecosystems. This research endeavors to scrutinize mollusk diversity within the rehabilitated mangrove areas of Tangerang.
Biota sampling was conducted between February and March 2022 across three designated stations: Ketapang Village (Station 1), Patramangala Village (Station 2), and Tanjung Pasir Village (Station 3), employing 1×1 m2 quadratic transects. Mollusk sampling entailed 15 repetitions per plot at each station. Water quality parameters were directly assessed in the field.
Mollusks encountered belonged to the classes Bivalvia and Gastropoda. Overall, mollusk abundance denotes the number of individual mollusks within a designated area. The distribution of mollusk species comprised 42% bivalves and 58% gastropods. The highest diversity index, uniformity index, and dominance index across the three villages were recorded as 1.8882, 0.6294, and 0.5183, respectively.
The findings underscore that mangrove rehabilitation fosters habitats conducive to mollusks, showcasing a commendable level of diversity. Furthermore, the duration of mangrove establishment exerts influence on the presence of macrozoobenthos, including mollusks. These outcomes signify the efficacy of rehabilitation efforts and contribute to the overall health of the ecosystem.
