Abstract

The Banyu Habang Ecotourism Area is a joint effort between PT ADARO Indonesia, local communities, and the South Barito administration. It is an important ecosystem in Indonesia, known for its rich biodiversity and ability to absorb and store carbon. The objective of this study was to evaluate the biodiversity and carbon stocks of the area, with the purpose of obtaining extensive data to guide conservation policies and sustainable management practices. The study utilized a combination of methods, including field surveys to collect data on plant and animal species using transects and plots, as well as estimating carbon storage by assessing biomass and utilizing mathematical models. The findings indicated a moderate level of diversity in the flora, as measured by the Shannon-Wiener indices. The indices ranged from 1.52 for trees to 2.12 for seedlings. Additionally, the study discovered some species of significant conservation value, such as the critically endangered Shorea belangeran and Shorea sp. A total of 22 bird species, 6 animal species (including the endangered long-tailed macaque), 9 herpetofauna species (highlighting the endemic Kalimantan Skink), and 12 arthropod species were recorded in the faunal surveys. The examination of carbon stock estimated a total of 322.54 tons per hectare across all species of plants, with Shorea sp. being the primary contributor. The carbon stocks were economically valued at a total of 69,944,794.92 in terms of conversion values. The results highlight the importance of ADARO Indonesia's CSR project in terms of its impact on the environment and its potential for economic benefits. The analysis determines that the region's abundant variety of living organisms and significant ability to capture and store carbon justify the need for specific conservation initiatives and sustainable methods of overseeing the area. Moreover, the assessment of the monetary value of carbon stocks presents a strong case for conserving the region. This implies that ADARO Indonesia might improve its environmental responsibility by engaging in carbon markets or Payment for Ecosystem Services programs.
