Abstract

Conservation forest in Indonesia holds the primary function as biodiversity preservation and maintains forest ecosystem, and therefore plays a significant role in reducing emission from deforestation and forest degradation (REDD) in East Kalimantan. To understand the forest’s role in holding emissions, information on current carbon standing stock is vital. This study aims to estimate above-ground carbon from East Kalimantan conservation forest, contributing up to 5.3% of the total forest area in this province. The study area is located at the Loa Haur education and training forest (Loa Haur forest) part of Bukit Soeharto Grand Forest Park. As many as 48 sample plots were established over 43.1 km2 of Loa Haur forests cover three main land cover types, i.e., secondary forest, shrub, and bare land. Above-ground biomass from sample plots was calculated using Chave allometric equations, while land cover types were derived from high-resolution Sentinel-2 satellite imagery. Carbon was estimated simply by multiplying biomass with a conversion factor of 0.47. Land cover of the study area was carefully classified using visual interpretation and was validated using actual land cover from the ground (sample plots). Accuracy assessment on land cover classification using Kappa value exhibited excellent results (Kappa index =0.83). This study also showed that the above-ground carbon stock of secondary forest, shrub, and bare land is 111.30 Mg/ha, 10.84 Mg/ha, and 4.63 Mg/ha, respectively. This above-ground carbon stock may refer to the emission factor, which can be used as a basis for calculating East Kalimantan carbon emission for a specific period.
