Potential of stock carbon in mangrove Sonneratia alba in Passo coastal waters, Inner Ambon Bay

Abstract

The increase in CO2 in the air has caused global warming, the impact of which is felt by everyone in the world. One way to control climate change is to reduce greenhouse gas emissions by maintaining the integrity of natural forests and increasing the density of trees outside the forest. Mangrove forests have a role as absorbers of CO2 from the air, and save more carbon than most tropical rainforests. The purpose of this study was to determine the biomass, stock carbon and CO2 uptake of mangrove Sonneratia alba in the Passo coastal waters, Inner Ambon Bay. Sampling of mangrove S. albaby belt transect method with a belt width of 10 m. Data collected included the number of trees, diameter (DBH) and area of observation. Biomass analysis and carbon content of S. albatrees were carried out in a nondestructive way (without damaging plants), which was using biomass estimation allometric equations. Carbon (CO2) uptakein S. alba is 564.48 tons.ha-1 which is stored on above of the ground at 111.50 tons.ha-1 and below the ground at 42.31 tons.ha-1. Total stock carbon of 153.81 tons.ha-1 were converted from total biomass of 327.26 tons.ha-1. High carbon sequestration and storage is supported by high biomass and high biomass is supported by a high number and diameter of trees.
