List of islands of Indonesia
The exact number of islands comprising Indonesia varies among definitions and sources. According to a geospatial survey conducted between 2007 and 2010 by Badan Koordinasi Survei dan Pemetaan Nasional (Bakorsurtanal), the National Coordinating Agency for Survey and Mapping, Indonesia has 13,466 islands. However, according to earlier survey in 2002 by National Institute of Aeronautics and Space (LAPAN), the Indonesian archipelago has 18,307 islands, and according to the CIA "World Factbook", there are 17,508 islands. The discrepancy of the numbers of Indonesian islands was because that the earlier surveys include "tidal islands"; sandy cays and rocky reefs that appear during low tide and are submerged during high tide. According to estimates made by the government of Indonesia 8,844 islands have been named, with 922 of those permanently inhabited.The following islands are listed by province:

Southeast Asian coral reefs
Indonesia has 2,915,000 square kilometers of marine area. The reef area is 51,020 square kilometers. Of that amount, 82% of it is at risk. Indonesia holds 17% of the world's total coral reef areas. Blast fishing, which has been illegal since 1985 still goes on today, along with cyanide fishing (1995). Another factor that is hurting the coral reefs in Indonesia is the amount of coral that they export. They are the world's largest exporter of corals, exporting about 500 tons of coral per year.
