This study analyzed vegetation structure and species diversity of mangrove forests in the Anggrek coastal area, Gorontalo, Celebes, Indonesia. Data were collected using the strip plot method, which integrates transects and plots. Vegetation structure was assessed by calculating Relative Density, Relative Frequency, and Relative Dominance to derive the Importance Value Index (IVI). The Shannon– Wiener index was used to quantify species diversity for each vegetation stratum. A total of 13 mangrove species were identified, representing five families: Acanthaceae, Lythraceae, Rhizophoraceae, and Meliaceae. The dominant species, Rhizophora mucronata, Rhizophora apiculata, and Ceriops tagal. Diversity index (H’) values ranged from 1.64 to 2.54, reflecting moderate species diversity, with Popalo Village displaying the highest diversity and evenness. Environmental parameters (soil pH 6.0-6.8, salinity 1.9-21 ppt, temperatures 29–31°C, and humidity levels 72%-79%), were found to be favorable for mangrove growth. These findings provide a critical ecological baseline, suggesting the Anggrek coastal mangrove forest has high potential for long-term Blue Carbon Stock. This data is essential for both conservation planning to sustain mangrove biodiversity and developing future carbon trading initiatives in Gorontalo. © 2026, Egyptian Society for the Development of Fisheries and Human Health.
