Giant Leatherback Turtle


  • Proposals for tourism and port development in the Andaman and Nicobar (A&N) Islands have conservationists worried over the fate of some of the most important nesting populations of the Giant Leatherback turtle in this part of the Indian Ocean. Giant Leatherback Turtle

Key Details

  • There is concern that at least three key nesting beaches — two on Little Andaman Island and one on Great Nicobar Island — are under threat due to mega “development” plans announced in recent months.
  • These include NITI Aayog’s ambitious tourism vision for Little Andaman and the proposal for a mega-shipment port at Galathea Bay on Great Nicobar Island.

Little Andaman in focus

  • The Little Andaman plan, which proposes phased growth of tourism on this virtually untouched island, has sought the de-reservation of over 200 sq km of pristine rainforest and also of about 140 sq km of the Onge Tribal Reserve.
  • Two sites where key components of the tourism plan are to be implemented are both Leatherback nesting sites — South Bay along the southern coast of the island and West Bay along its western coast.
  • South Bay is proposed to be part of the “Leisure Zone” where a film city, a residential district and a tourism special economic zone are to come up.
  • West Bay is to be part of West Bay Nature Retreat with theme resorts, underwater resorts, beach hotels and high-end residential villas.

Great Nicobar Island

  • For the Leatherback, perhaps even more important is Great Nicobar Island, the southernmost of the A&N group.
  • Large numbers have been recorded nesting here — mainly on the long and wide beaches at the mouth of the Dagmar and Alexandira rivers on the west coast and at the mouth of the Galathea river along its south eastern coast.
  • Galathea Bay was, in fact, proposed as a wildlife sanctuary in 1997 for the protection of turtles and was also the site of a long-term monitoring programme.

About Giant Leatherback Turtle

  • The largest of the seven species of sea turtles on the planet and also the most long-ranging, Leatherbacks are found in all oceans except the Arctic and the Antarctic. Within the Indian Ocean, they nest only in Indonesia, Sri Lanka and the Andaman and Nicobar Islands and are also listed in Schedule I of India’s Wildlife Protection Act, 1972, according it the highest legal protection.
  • Note: The A&N Islands are prominent in the National Marine Turtle Action Plan released on February 1, 2021, by the Ministry of Environment, Forest and Climate Change.
  • The plan notes that “India has identified all its important sea turtle nesting habitats as ‘Important Coastal and Marine Biodiversity Areas’ and included them in the Coastal Regulation Zone (CRZ) – 1”. South Bay and West Bay on Little Andaman and Galathea on Great Nicobar, along with other nesting beaches in the islands, find a specific mention here as “Important Marine Turtle Habitats in India” and the largest Leatherback nesting grounds in India.

Galathea National Park

  • National Park located in the Union Territory of Andaman and Nicobar Islands, India.
  • Located on the island of Great Nicobar in the Nicobar Islands, which lie in the eastern Indian Ocean.
