Abstract

Mangrove ecosystems play a crucial role in carbon sequestration, functioning as significant carbon sinks in tropical coastal areas. This study aimed to analyze the relationship between vegetation structure, natural regeneration, and sediment carbon storage in mangrove forests of Sorong City, Southwest Papua, Indonesia. Data on species composition, seedling density, and sediment carbon content were collected from three stations representing different regeneration levels. The results revealed a positive correlation between regeneration density and sediment carbon storage, where stations with moderate regeneration (1,000–3,000 seedlings ha⁻¹) stored higher carbon stocks (10,718.42–10,946.87 gC m⁻²) compared to stations with low regeneration (<1,000 seedlings ha⁻¹; 10,431.71 gC m⁻²). These findings indicate that natural regeneration significantly influences sediment carbon retention, likely due to organic matter inputs from litterfall and root biomass accumulation. The study highlights the importance of conserving and restoring mangrove forests to enhance their carbon sequestration capacity. Conservation strategies should prioritize maintaining balanced regeneration structures to optimize carbon storage potential. These results contribute to the broader discussion on nature-based solutions for climate change mitigation through sustainable mangrove ecosystem management.
