Biodiversitas 23: 2830-2837. Tropical forests can store high amounts of carbon because they have suitable environmental factors. Furthermore, they are different from others that grow in dry areas, which tend to experience limited rainfall. Ampupu (Eucalyptus urophylla) is an endemic tree in East Nusa Tenggara, which is continuously damaged. This is caused by various anthropogenic activities, which increase along with the population around the forest. Therefore, this study aims to estimate the carbon content stored in natural forest areas of E. urophylla at different density levels and land use types. Field inventory was carried out in the study location using the stratified sampling method, after which the density levels were divided into three groups, viz. high, medium, and low. Sampling was then carried out in 3 different land-use areas, including production, protection, and conservation forests. Furthermore, a total of 90 plots were used, where each land-use type consists of 30 plots with a size of 25 m × 40 m. The results showed that the carbon content at the low, medium and high-density levels were 108.20, 185.24, and 291.33 MgCha-1, respectively. Values of 211.91, 214.69, and 221.14 MgCha-1 were also obtained from the production, protection, and conservation forests, respectively. Based on the results, the natural forests of E. urophylla have a significant effect on carbon sequestration in East Nusa Tenggara.
