Abstract

Mangrove forests are important in climate mitigation, particularly for their greatest carbon storage. Rhizophora apiculata, a mangrove species with numerous advantages, is frequently employed in restoration activities. Monoscpecies restoration activities are well known, although information on floristic composition and carbon uptake must be available. The objective of this research was to investigate the floristic composition and carbon stock of R. apiculata in the Pasar Rawa Village restoration area, Langkat Regency, North Sumatra Province. This study employed the vegetation analysis approach and carbon estimates based on diameter breast height (DBH) and total vegetation height. The study's findings indicate low floristic diversity in the research area. At the seedling stages, the greatest IVI (113.68%) was discovered in Achanthus ilicifolius, and the only species found in the sapling stage with an IVI value of 200% was R. apiculata. The study of diversity indices revealed very low values at the seedling stage (H'= 0.806) and no diversity at the sapling stage. The total carbon stored estimation in R. apiculata stands relatively low, at 8.56 tonnes/ha. The absorbed carbon produced by R. apiculata is 31.42 tons/ha with a CO2 absorption of 3.141 g/m2 and is classified as relatively low

Abstract

Pante Bayam is one of natural mangrove area in Aceh Province. Due toanthropogenic activities such as fishpond, the area become degradated. This studyaims to analyze soil organic carbon (SOC) stock based on soil depth and texturecharacteristics at several observation points in the study area. Data were collectedfrom seven sample locations with four categories of soil depth: 0–15 cm, 15–30cm, 30–50 cm, and 50–100 cm. The results showed that the highest carbon stockwas found at a depth of 50–100 cm, reaching 159.1 Mg C/ha, while the 15–30 cmlayer had the lowest carbon stock. This indicates that the subsoil plays a significantrole in long-term carbon storage. The distribution of carbon stocks also variedbetween locations, where PB04 and PB07 showed the highest values, while PB05and PB06 showed the lowest. Correlation analysis showed a positive relationshipbetween clay content and soil carbon stock, indicating that fine soil texturesupports carbon accumulation through the formation of stable aggregates. Thesefindings emphasize the importance of soil management that considers soil depthand physical characteristics to increase the potential for climate change mitigationthrough sustainable soil carbon storage
