Site description The Nicobar Islands can be divided into three distinct subgroups: the Great Nicobar subgroup, the Nancowry subgroup and the Car Nicobar subgroup. Tillanchong, Camorta, Katchal, Nancowry and Trinkat Islands lie in the Nancowry subgroup of islands, c. 58 km north of the Great Nicobar subgroup. This subgroup consists of 10 islands and smaller islets of which one island and two islets are uninhabited (Sankaran 1998). Of these, three islands are larger than 100 sq. km, two are 36 and 67 sq. km and three are less than 17 sq. km. Tillanchong is uninhabited and a wildlife Sanctuary (Sankaran 1995). The climate of these islands can be defined as humid, tropical coastal. The islands receive rainfall from both the southwest and northeast monsoon, with maximum precipitation between May and December, and the driest period between January and April (Sankaran 1995). The forest type of the Nicobar Islands can be broadly classified as Andaman Tropical Evergreen, Andaman Semi-Evergreen, Littoral Forest and Tidal Swamp Forest (Mangrove), the inland areas being either forested or grasslands, and a significant proportion of the coast being mangroves.
