The Great Nicobar Biosphere Reserve encompasses a large part of the island of Great Nicobar, the largest of the Nicobar Islands in the Indian Union Territory of Andaman and Nicobar Islands. It incorporates two National parks of India, which were gazetted in 1992: the larger Campbell Bay National Park on the northern part of the island, and Galathea National Park in the southern interior. The reserve is home to many species of plants and animals, often endemic to the Andaman and Nicobars bio-geographic region.
