Mangrove forest has a significant role in sequestering carbon gases from the atmosphere but there are lesser literature has been made on it. This research was conducted to quantify the aboveground, belowground and soil carbon stock in Sulaman Lake Forest Reserve, Sabah, Malaysia. Nine transect lines with 125 m length were established and a circle with 7 m radius was set in every 25 m. Forest inventory was done to get the diameter breast height of standing trees and soil sampling with four different depths (0-15 cm, 15-30 cm, 30-50 cm and 50-100 cm) were taken for soil analysis and bulk density. Allometric equation was used to calculate aboveground and belowground biomass then its carbon stock was estimated as 50% from its total biomass. The result shows the total carbon stock in the study area was 441.72 Mg C ha-1, and soil has the highest value of carbon stock (351.98 ± 11.73 Mg C ha-1) followed by aboveground carbon (67.30 ± 20.55 Mg C ha-1) and belowground carbon (22.44 ± 0.17 Mg C ha-1). This study found that soil carbon stock made up almost 80% of the total carbon stock in the mangrove forest. This ecosystem also shows a higher value of carbon stock compared to other locations hence emphasized the importance of prioritizing a mangrove forest in any climate mitigation efforts.

Species composition, stand characteristics, aboveground biomass, and carbon stock of mangroves in Panabo Mangrove Park, Philippines

“…Globally, the estimated biomass and stored carbon of Panabo Mangrove Park were relatively higher than those of the oligohaline zone of Dhangmari area, Sundarbans, Bangladesh (Kamruzzaman et al 2018) (Bhomia et al 2016). However, these estimates were not as high as those in neighboring Asian countries such as Vietnam (Nam et al 2016), Malaysia (Hossain 2014;Ismail et al 2015;Suhaili et al 2020), Indonesia (Murdiyarso et al 2015;Alongi et al 2016;Asadi et al 2018;Widyastuti et al 2018), India (Kathiresan et al 2013;Hebbalalu et al 2014;Sahu et al 2016) and H. fomesdominated vegetation in Sundarbans, Bangladesh (Rahman et al 2015). Further, this account was even lower than the records in East Coast, Florida (Doughty et al 2016) and several African countries such as Liberia (Tang et al 2016;Kauffman and Bhomia 2017), Mozambique (Sitoe et al 2014;Trettin et al 2016), Tanzania (Alavaisha and Mangora 2016), Cameroon (Tang et al 2016) and Gabon (Kauffman and Bhomia 2017).…”
