The Andaman Islands are a group of Indian Ocean archipelagic islands in the Bay of Bengal, between the Indian peninsula to the west and Burma to the north and east. The Middle Andamans harbour mostly moist deciduous forests. North Andamans is characterized by the wet evergreen type, with plenty of woody climbers.
The natural vegetation of the Andamans is tropical forest, with mangroves on the coast. The rainforests are similar in composition to those of the west coast of Burma. Most of the forests are evergreen, but there are areas of deciduous forest on North Andaman, Middle Andaman, Baratang and parts of South Andaman Island. The South Andaman forests have a profuse growth of epiphytic vegetation, mostly ferns and orchids.
The Andaman forests are largely unspoiled, despite logging and the demands of the fast-growing population driven by immigration from the Indian mainland. There are protected areas on Little Andaman, Narcondam, North Andaman and South Andaman, but these are mainly aimed at preserving the coast and the marine wildlife rather than the rainforests. Threats to wildlife come from introduced species including rats, dogs, cats and the elephants of Interview Island and North Andaman.
