Estimation of Above and Below Ground Carbon Stock in Baros Mangrove Conservation Area, Bantul Regency - Indonesia

Mangroves are vital coastal ecosystems that provide numerous ecological benefits, including carbon sequestration, which plays a crucial role in mitigating climate change. The Baros Mangrove Conservation Area in Bantul Regency is an essential site for studying these valuable ecosystems, given its diverse mangrove species and varying age structures. This study aims to determine the distribution of mangrove species and estimate the above-ground carbon (AGC) and below-ground carbon (BGC) stock values in the Baros Mangrove Conservation Area, Bantul Regency. Data were collected using purposive sampling from four sample plots selected based on species differences, planting age, and site accessibility. Species identification was conducted through high-resolution aerial imagery and field validation. The results indicate that the dominant mangrove species are Avicennia sp. and Rhizophora sp., with the highest AGC found in Plot 2 at 198.14 tons/ha and the highest BGC also in Plot 2 at 121.36 tons/ha. Plot 2, which features the most mature vegetation, shows the highest carbon storage capacity, while Plot 4, dominated by younger mangroves, has the lowest AGC and BGC at 46.05 tons/ha and 40.70 tons/ha, respectively. With a total AGC and BGC carbon stock of 411.32 tons/ha for AGC and 601.28 tons/ha. This study underscores the importance of mangrove conservation and management, particularly in plots with mature vegetation, to maintain significant carbon reserves for climate change mitigation. © 2025 Institute of Physics Publishing.
