<![CDATA[Seagrass meadows contribute to coastal carbon sequestration through biomass accumulation in plant tissues and sediments. This study quantified dry seagrass biomass along the coast of Bahoi Village, North Sulawesi, using original field data collected in May 2017. Three stations representing a mangrove-adjacent area, a seagrass meadow, and a coral-reef-adjacent area were selected purposively, with three replicate sampling units at each station. Seagrasses within 50 × 50 cm quadrat frames were collected, cleaned, oven-dried for 24 h, separated into leaves, rhizomes, and roots, and weighed. Six species were recorded. Enhalus acoroides had the highest mean biomass at all stations, reaching 75.7 g DW m−2 at Station 1, 68.9 g DW m−2 at Station 2, and 58.6 g DW m−2 at Station 3; Thalassia hemprichii reached 45.7 g DW m−2 at Station 2. Total biomass did not differ significantly among stations (p = 0.379), whereas species-specific ANOVA detected differences for E. acoroides (p = 0.032) and Syringodium isoetifolium (p = 0.026). Large-bodied seagrasses contributed most strongly to standing biomass. The 2017 dataset provides a baseline for future assessment of biomass-related blue-carbon functions in Bahoi coastal habitats]]>
