Modeling above ground biomass, soil carbon determination and economic value of carbon stock of selected mangrove species in Marudu Bay, Sabah, Malaysia

The forest absorbs CO2 during photosynthesis and stores it as organic material in plant biomass and soil. In Malaysia, accurate information on aboveground and soil carbon in the mangrove forests is lacking. Hence, the objectives of this study were to create allometric model for four selected species...
