To obtain vegetation data, the quadrant transect method was used at three stations. The mangrove community structure analysed was the Important Value Index (INP), and the ecological indices analysed were the Diversity Index, Uniformity Index, and Dominance Index. The study's results indicate that there are 11 true mangrove species. The highest INP at the tree level was R. apiculata (154.743%), followed by B. gymnorrhiza (59.696%) and R. mucronata (26.655%). At the sapling and seedling level, R. apiculata also had the highest INP. The species uniformity index at the tree level ranged from 0.595 to 0.625. For the sapling level, it ranged from 0.626 to 0.786. At the seedling level, it ranged from 0.768 to 0.772. This shows that the distribution of mangrove individuals in the study area tends to be even, or at least highly uniform. Furthermore, this study's findings demonstrate that, even within a relatively short 9-month implementation period, the Tasamu approach has contributed to natural mangrove restoration. Nevertheless, the ecosystem remains under pressure, and inclusive, sustainable management efforts need to continue. }, issn = {2407-7690}, pages = {89--103} doi = {10.14710/jmr.v15i1.50692}, url = {https://ejournal3.undip.ac.id/index.php/jmr/article/view/50692} }
