Abstract
Carbon storage in forest ecosystems involves inordinate components including plant biomass carbon and soil carbon. Sequestration of carbon along with other aggressive conservation efforts helps to reduce the increasing negative impact of global warming on the environment and mangroves as the coastal forest. The objective of this study was to assess the soil carbon storage of dominant plant species of Awat-Awat Mangrove Forest, Sarawak, Malaysia. A total of 32 soil samples of mangrove forest were collected in nine different plots with different species using a peat auger at a soil depth of 0 to 50 cm. The total C in the soil samples was analyzed using CHNS analyzer (TruSpec Micro Elemental Analyzer (NCHS), LECO, USA). Soil carbon content of mangrove forest was found varies in each plot. The highest soil carbon content in Awat-Awat Mangrove Forest was found for soil under dominance of Rhizophora mucronata (6.24%) whereas the lowest (1.73%) was found for soil under dominated by Sonneratia alba. The soil carbon content of Awat-Awat Mangrove Forest was found to be influenced by the difference in species dominance. Key words: Soil carbon storage, soil carbon, species dominance, mangrove forest, Sarawak, Malaysia.
Highlights
Among all of source of life on the earth, carbon is one of the primary one
Carbon sequestration is the carbon that is stored in long term which is available in the oceans, soils, vegetation, and geologic formation (ESA, 2000)
The soils of Awat-Awat Mangrove Forest were acidic with an average pH of 4.63
Summary
Among all of source of life on the earth, carbon is one of the primary one. It is found in all living organism and obtainable in many forms, mostly as tree biomass, soil organic matter and as gasses (CO2) in the atmosphere.Carbon is the major component of soil organic matter, but its content can vary from 48 to 60% or more of the weight of soil organic matter (Tan, 2005).
