Condition of coral reefs in East Belitung, Bangka Belitung Islands, Indonesia

Belitung Island has abundant fishery resources. In terms of the coastal ecosystem, Belitung Island has three crucial components, namely the mangrove, seagrass, and coral reef ecosystems. The purpose of the present study is to examine the diversity of coral reefs in the coastal areas of the eastern part of Belitung Island. Sampling locations are in Pekandis Island, Gosong Semut, and Keran Island. The results show that the diversity of coral reef in this region is medium based on the Shannon-Wiener Diversity Index. High evenness of species distribution and no dominant species was indicated. This study concludes that coral reef in East Belitung was not affected by external factors at the time of study, but new studies are needed.
