A proposed coastal surveillance Radar and power supply installation in the Narcondam island threatens the future of perhaps the rarest and endemic Narcondam hornbill (Aceros narcondami). Only about 90 mature breeding pairs are present in the island, and the species is categorised as "endangered" by the International Union for Conservation of Nature. The proposal indicates that only 0.67 ha of the island will be affected, but Dr. Asad Rahmani of the Bombay Natural History Society mentions that 'the total area to be directly damaged is likely to be much higher'. The road that will be constructed to the Radar installation will lead to further instability of the volcanic island. Nature Conservation Foundation, Mysore points out that at least 20 ha of the island will be affected by the road and the installation directly and about 400 ha, indirectly. Besides affecting the hornbill, the project will affect the coral reefs as well as increase the threat from invasive alien species to the island. This proposal needs to be rejected to ensure survival of the Narcondam hornbill as well as to protect the island from collateral threats from the Radar Project.
