Abstract

Mangrove forests are one of the most productive and efficient long-term natural carbon sinks, tropical natural resources that have social, economic and ecological benefits. Even though the area of mangrove forests is relatively large in of the world, the consequences of various anthropogenic cause various damages. Given their global significance as a large carbon sink, preventing mangrove loss would be an effective climate change adaptation and mitigation strategy. This research was conducted to analyse the carbon stock in the mangrove forest for the rehabilitation of former ponds in the village of Lubuk Kertang, Brandan Barat District, Langkat, North Sumatra, Indonesia. The census method was applied in this study, to calculate the value of carbon stocks using an allometric equation with DBH > 5cm. The aboveground biomass was 15.54 Mg/ha. Soil sampling for organic carbon content by collecting a sub-sample 5 cm from the center of the core. The total value of the total carbon stock above and below the soil surface is 9.42 Mg/ha1 and soil carbon is 685 MgC/ha1.
