Great Nicobar Biosphere Reserve The Great Nicobar Biosphere Reserve on Great Nicobar Island is a federally designated conservation landscape in the Andaman and Nicobar Islands of India created to protect tropical rainforest and coastal ecosystems. The reserve encompasses lowland evergreen forests, mangrove belts, littoral zones and marine habitats and lies near strategic sea routes such as the Malacca Strait and the Bay of Bengal. It is managed under national conservation frameworks and international programmes linked to UNESCO biosphere objectives.

Introduction

The reserve was created in 1989 under Indian environmental policy instruments and aligns with UNESCO's Man and the Biosphere Programme and national biodiversity strategies administered by the Ministry of Environment, Forest and Climate Change (India). The designation recognizes the area's roles in regional biodiversity conservation, indigenous cultural landscapes associated with the Shompen people and Nicobarese people, and its ecological connectivity with neighbouring island groups such as Little Andaman Island. Management is coordinated through state and central agencies including the Andaman and Nicobar Islands Forest Department and research bodies such as the Zoological Survey of India.

Geography and Climate

Located at the southern tip of the Andaman and Nicobar Islands archipelago, the reserve occupies much of Great Nicobar Island, featuring terrain from coastal mangroves and sandy beaches to interior hills and plateaus. Prominent geographic features include Galathea Bay and Puyemkondin Bay as well as proximity to maritime passages like the Andaman Sea. The climate is equatorial maritime with a strong southwest monsoon and northeast monsoon regime, influenced by the Indian Ocean and characterised by high rainfall, humidity, and relatively stable temperatures recorded at meteorological stations such as those administered by the India Meteorological Department.

Biodiversity and Ecosystems

The reserve contains multiple ecosystems: lowland evergreen rainforest, tropical moist deciduous forest, mangrove forests, coral reef systems, and seagrass beds associated with the Indian Ocean bioregion. Flora inventories cite endemic and regionally significant taxa alongside genera documented by the Botanical Survey of India. Fauna includes flagship mammals such as the Nicobar megapode-associated avifauna, the Nicobar scrubfowl, large mammals referenced in surveys by the Wildlife Institute of India and marine species like olive ridley sea turtle and green sea turtle nesting at beaches studied by Wildlife Trust of India. Herpetofauna and invertebrate assemblages have been catalogued in reports by the Zoological Survey of India and linked academic institutions including Jawaharlal Nehru University and Indian Institute of Science. Coral reef communities host reef-building corals and are tied to regional studies by organisations such as the National Centre for Coastal Research.

Conservation and Management

Management frameworks combine statutory protection under Indian law with site-level planning by the Andaman and Nicobar Islands Forest Department and technical inputs from the Ministry of Environment, Forest and Climate Change (India), Indian Council of Forestry Research and Education, and international partners including UNESCO. Conservation measures address protected-area zoning, habitat restoration, species recovery initiatives, and community conservation projects implemented with local stakeholders such as the Nicobarese people and NGOs like the Tropical Biodiversity Trust. Legal instruments interacting with the site include national wildlife statutes and environmental impact assessment procedures overseen by entities such as the Central Empowered Committee and tribunals referenced in environmental jurisprudence.

Human Inhabitants and Socioeconomic Context

Indigenous groups such as the Shompen people and the Nicobarese people have traditional land-use systems within the protected matrix, practising subsistence activities documented by ethnographers and agencies like the Anthropological Survey of India. Settlements, livelihoods, and cultural heritage intersect with infrastructure and development proposals debated at bodies including the Andaman and Nicobar Islands Administration and subject to assessment under national policy frameworks. Economic activities linked to the reserve involve small-scale fishing, forest resource use, limited agroforestry, and community tourism initiatives promoted in collaboration with organisations such as the Ministry of Tourism (India).

Threats and Environmental Pressures

The reserve faces pressures from natural and anthropogenic drivers: seismic events including the 2004 Indian Ocean earthquake and tsunami demonstrated vulnerability to tectonic hazards; climate change impacts such as sea-level rise and altered monsoon patterns reported by the Intergovernmental Panel on Climate Change increase risk to coastal and coral systems. Development proposals—transport infrastructure, port projects, and energy schemes—have raised concerns among conservationists and rights advocates represented in forums such as the National Human Rights Commission (India). Invasive species, illegal resource extraction documented by enforcement agencies, and emerging disease risks tracked by public health authorities compound conservation challenges.

Research, Monitoring, and Education

Scientific research within the reserve is undertaken by national agencies—the Zoological Survey of India, Botanical Survey of India, Indian Council of Agricultural Research—and academic institutions like Indian Institute of Technology Madras and University of Delhi, often in collaboration with international partners. Monitoring programmes cover biodiversity inventories, coral reef health surveys by the National Centre for Coastal Research, and socioeconomic studies by the Centre for Development Studies. Environmental education and community outreach are supported by NGOs and government schemes aligned with UNESCO biosphere education objectives, promoting capacity building among local communities, field-based training, and publication of management plans used by practitioners and policymakers.
