These islands lying in the Bay of Bengal were once a hill range stretching from Sumatra, 120 kms to the south of Burma. Many of these islands are still covered with rich tropical evergreen and tropical moist deciduous forests and are home to many endemic birds and reptiles. Most of the mammals are introduced species. Not only is the bird and forest life fascinating, but many islands are refuges for ancient and highly threatened indigenous people struggling to maintain their tradition and identify despite the pressures of the 21st century.
The temperature of the islands ranges from 20-30 C with the rainy season from June to December. Most of the areas are established for plants, birds and marine life. Most mammals are rodents and bats although introduced species include Andaman pig, chital, hogdeer, elephant and palm civet. Of the indigenous mammals the crab-eating or Nicobar macaque, the Nicobar tree shrew and the dugong are significant. Of the 255 bird species, 112 are endemic to the islands and many are highly endangered.
