Abstract

The Andaman & Nicobar Islands are a low mountainous chain of islands, which rise from a submerged north-south trending ridge separating the Andaman Sea from the Bay of Bengal between 6°45ʹ13ʹʹ.41 N and 92°12ʹ93ʹʹ.57 E. This island group includes 306 islands and 226 rocks, with a coastline of about 1962 kilometers. The islands located north of 10° N Latitude are known as Andamans (Figure 1) while those located south of 10° N Latitude are called Nicobars with a total area of 8249 square kilometers. These islands are supposed to have arisen from the ocean bed in the Mesozoic period about 110 million years ago and have since then undergone several periods of partial submergence and elevation. Fringing, Patch and Barrier reefs are present here, covering about 948.8 square kilometers. The total mangrove area is approximately 762 km2. There are 106 Protected Areas, 96 designated as wildlife sanctuaries, 9 National Parks and one Biosphere reserve. Among the 9 National Parks, 2 are Marine National Parks (Mahatma Gandhi Marine National Park and Rani Jhansi Marine National Park).
