This study provides a comprehensive assessment of forest biomass and carbon stocks for natural forests in Central Kalimantan. Total forest biomass estimates are presented for three main natural forest types (dryland, swamp and mangrove forests) with two different conditions (primary and secondary forests). These values quantify initial forest biomass conditions for modeling greenhouse gas (GHG) emissions and removals, as used in the Indonesian National Carbon Accounting System (INCAS), or to calculate CO 2 emission factors for quantifying GHG emissions due to forest clearing or deforestation in Central Kalimantan. Several sources of forest inventory data and information available from previous study were used in estimating forest biomass. This result provides an improved and more comprehensive analysis of emissions factors for forests by using Central Kalimantan-based forest inventory plots and allometric guidelines for quantifying forest biomass and forest carbon content. In addition, it includes all components of aboveground biomass of forest ecosystem. Further research is needed to relate forest biomass and carbon stocks to other determining factors such as forest type, soil type and climate, as well as the proportions of biomass immediately emitted due to forest management activities and the portion of biomass decomposed over specified time intervals.
