Great Nicobar Biosphere Reserve: India’s Southernmost UNESCO Biosphere Reserve

Most people first hear about Great Nicobar because of recent development proposals. However, long before these debates, the island was internationally recognised as one of India’s most important conservation landscapes. Its tropical rainforests, endemic wildlife, coastal ecosystems, and indigenous communities make it significant not only within India but also across the Indo-Pacific region.

Unlike many protected areas that focus solely on wildlife, Great Nicobar Biosphere Reserve combines biodiversity conservation with carefully managed human use. It includes national parks, reserved forests, coastal habitats, and areas where indigenous communities continue their traditional way of life. This broader approach is what distinguishes a biosphere reserve from many other protected area categories.

For travellers, researchers, birdwatchers, and conservation enthusiasts, understanding the reserve requires looking beyond a simple destination guide. Access is restricted, tourism opportunities are limited, and much of its importance lies in protecting fragile island ecosystems rather than promoting conventional sightseeing.

What Is Great Nicobar Biosphere Reserve?

Great Nicobar Biosphere Reserve is a protected conservation landscape located on Great Nicobar Island, the southernmost island of the Nicobar archipelago in the Andaman and Nicobar Islands. Covering roughly 104,000 hectares, it protects one of India’s largest remaining tropical wet evergreen forest ecosystems along with extensive coastal and marine habitats.

The reserve gained international recognition under UNESCO’s Man and the Biosphere (MAB) Programme in 2013, highlighting its global ecological importance. It also forms part of an internationally recognised Key Biodiversity Area because of its concentration of endemic and threatened species.

Why the Reserve Is Important

Great Nicobar stands out for several reasons:

• Tropical evergreen rainforests covering much of the island
• High levels of species found nowhere else
• Important nesting beaches for leatherback sea turtles
• Habitat for rare birds, mammals and reptiles
• Extensive coastal forests, mangroves and coral reef ecosystems
• Presence of indigenous Shompen and Nicobarese communities living alongside protected landscapes

Biosphere Reserve vs National Park

Many visitors assume that the biosphere reserve and the national parks are the same. They are not.

A biosphere reserve is a larger conservation landscape that includes different management zones. Within Great Nicobar Biosphere Reserve, Campbell Bay National Park and Galathea National Park form important protected core areas, while surrounding buffer and transition zones allow carefully managed human activities that support conservation objectives.

Field Note: Thinking of the biosphere reserve as an umbrella helps avoid confusion. The national parks are individual protected areas within the much larger biosphere reserve.

Where Is Great Nicobar Biosphere Reserve Located?

The reserve occupies much of Great Nicobar Island, the largest and southernmost island in India’s Nicobar group. It lies in the eastern Indian Ocean, separated from mainland India by hundreds of kilometres of sea and much closer to Southeast Asia than most Indian protected areas.

Its landscape is remarkably varied for an island. Visitors and researchers encounter:

• Mountain ranges rising to Mount Thullier
• Numerous perennial rivers and streams
• Dense tropical evergreen forests
• Coastal plains
• Sandy beaches
• Mangrove habitats
• Coral reef systems along the coastline

This combination of mountains, forests, freshwater systems, beaches, and marine habitats supports an exceptional diversity of life within a relatively compact area.

Why Geography Matters

The island’s isolation has allowed many species to evolve independently over thousands of years. As a result, Great Nicobar supports numerous endemic mammals, birds, reptiles, amphibians, and plants that occur nowhere else. This geographic isolation is one of the main reasons the reserve has become internationally important for conservation and scientific research.

Part 2: Understanding the Biosphere Reserve and Its Biodiversity

Understanding the Biosphere Reserve Zoning

One of the easiest ways to understand Great Nicobar Biosphere Reserve is to think of it as a conservation landscape with different levels of protection. Instead of treating the entire reserve the same way, UNESCO’s biosphere reserve model divides it into zones that balance wildlife conservation, scientific research, and carefully managed human activities.

Core Zone: Strictly Protected Wildlife Habitat

The core zone forms the ecological heart of the biosphere reserve. These areas receive the highest level of protection and are managed primarily to conserve natural ecosystems and wildlife.

The core includes:

• Campbell Bay National Park
• Galathea National Park

These forests protect tropical evergreen habitats, mountain ecosystems, river catchments, and important nesting beaches used by threatened marine species. Human activity is highly restricted and generally limited to conservation management and scientific research.

Buffer Zone: Supporting Conservation

Surrounding the core is the buffer zone, where activities compatible with conservation may be permitted under regulation. Scientific studies, environmental monitoring, education, and carefully managed resource use can take place without compromising the integrity of the core habitats.

Transition Zone: People and Nature Together

The transition zone represents the outer part of the biosphere reserve, where local communities and conservation coexist. Here, sustainable livelihoods and responsible resource use are encouraged while maintaining the ecological health of the wider landscape.

This zoning recognises that conservation is often most effective when people and nature are managed together rather than being completely separated.

Comparison: Biosphere Reserve vs National Park vs Wildlife Sanctuary

Decision Guide: If you are researching Great Nicobar, remember that the biosphere reserve is the larger conservation landscape, while the national parks are individual protected areas within it.

Campbell Bay National Park

Campbell Bay National Park occupies part of the reserve’s protected core and safeguards extensive tropical evergreen forests. Together with neighbouring protected areas, it provides habitat for many endemic mammals, birds, reptiles, and invertebrates.

Its forests also help protect watersheds and support ecological processes that extend well beyond the park boundaries. Because island ecosystems are naturally isolated, maintaining large, connected forest areas is especially important for long-term species survival.

Galathea National Park

Located in the southern part of Great Nicobar Island, Galathea National Park protects forests, rivers, and coastal habitats that are internationally recognised for their ecological importance.

The park is particularly significant because its coastline includes important nesting habitat for the Leatherback Sea Turtle, the world’s largest marine turtle. Nearby coastal ecosystems also support mangroves, estuaries, and coral reef environments that contribute to the island’s exceptional biodiversity.

Why Great Nicobar Is a Global Biodiversity Hotspot

Although Great Nicobar is only one island within the Nicobar archipelago, its combination of isolation, varied terrain, and tropical climate has produced an unusually high concentration of endemic species.

According to the research brief, the biosphere reserve supports:

• More than 1,800 recorded animal species
• Around 650 recorded plant species, including flowering plants, ferns, gymnosperms, bryophytes, and lichens
• Numerous endemic mammals, birds, reptiles, and amphibians found only in the Nicobar Islands

This diversity is one of the primary reasons UNESCO recognised the reserve under its Man and the Biosphere Programme.

Tropical Evergreen Forests

The dominant habitat across much of Great Nicobar is tropical wet evergreen forest.

These forests receive heavy rainfall throughout the year and support multiple vegetation layers, from towering canopy trees to dense understory plants, climbers, orchids, ferns, and palms.

Beyond providing habitat for wildlife, the forests also:

• Protect soil from erosion
• Regulate freshwater systems
• Store carbon
• Moderate local climate
• Support pollinators and seed dispersal

Because island forests recover slowly after disturbance, maintaining intact forest cover is particularly important.

Coastal and Marine Ecosystems

The biosphere reserve extends beyond forests. Its coastal environments are equally important and include:

• Sandy beaches
• Mangrove forests
• Estuaries
• Coral reefs
• Seagrass habitats

These ecosystems provide breeding and feeding grounds for numerous marine species, including dugongs and sea turtles, while also protecting the coastline from storms and erosion.

Field Note: Healthy coastal forests and coral reefs are closely connected. Forests reduce sediment runoff into the sea, helping coral reefs remain productive, while reefs lessen wave energy reaching the shoreline.

Why Endemism Matters

One of Great Nicobar’s defining characteristics is its high level of endemism.

An endemic species is one that naturally occurs only within a specific geographic region. Because Great Nicobar has remained geographically isolated for thousands of years, many species evolved independently and are found nowhere else on Earth.

This makes habitat loss especially significant. If an endemic species disappears from Great Nicobar, it may become globally extinct because no other wild populations exist elsewhere.

Expert Tip: When comparing Indian protected areas, avoid focusing only on the number of species. Great Nicobar’s greatest conservation value lies in the uniqueness of its wildlife rather than sheer species count.

End of Part 2.

Part 3: Wildlife of Great Nicobar Biosphere Reserve

Great Nicobar Biosphere Reserve is best known for its endemic wildlife rather than sheer numbers of animals. Its long isolation has allowed many species to evolve independently, making the island one of India’s most important centres of island biodiversity. From rare forest mammals to nesting sea turtles and endemic birds, the reserve supports species that are difficult—or impossible—to see elsewhere.

Mammals of Great Nicobar

Although the island lacks the large mammals commonly associated with mainland Indian wildlife, its smaller mammals are of exceptional scientific importance because many are endemic.

Nicobar Tree Shrew

The Nicobar Tree Shrew is among the island’s best-known endemic mammals. Despite its name, it is more closely related to primates than to true shrews. It spends much of its time foraging on the forest floor and in low vegetation, feeding on insects, fruits, and other small food items.

Its dependence on intact tropical forests makes it an important indicator of habitat quality.

Dugong

The Dugong, often called the sea cow, inhabits shallow coastal waters where seagrass meadows remain healthy. Dugongs are slow-moving marine mammals that play a vital role in maintaining productive seagrass ecosystems through grazing.

The waters around Great Nicobar continue to provide important habitat for this threatened species, although sightings are naturally uncommon.

Coconut Crab (Robber Crab)

One of the island’s most unusual residents is the Coconut Crab, the world’s largest terrestrial arthropod.

Despite its common name, it does not rely exclusively on coconuts. It feeds on fruits, seeds, carrion, and other organic material, contributing to nutrient recycling within coastal forests.

Because it requires relatively undisturbed coastal habitats, the species is often regarded as an indicator of healthy island ecosystems.

Birds of Great Nicobar

Birdwatchers value Great Nicobar for its concentration of endemic and range-restricted species. Several birds found here occur only within the Nicobar Islands.

Nicobar Megapode

The Nicobar Megapode is perhaps the reserve’s most iconic bird.

Unlike most birds, megapodes do not incubate their eggs with body heat. Instead, they build large nesting mounds of sand, soil, and decaying vegetation. Heat produced by decomposition naturally incubates the eggs, while adults carefully regulate the mound’s temperature.

This unusual breeding strategy makes the species one of the most fascinating birds in India.

Nicobar Pigeon

The Nicobar Pigeon is among the world’s most striking pigeons, recognised by its metallic green and blue plumage and elongated neck feathers.

Although it occurs on several islands across Southeast Asia, Great Nicobar remains an important part of its natural range. It plays a valuable ecological role by dispersing seeds through tropical forests.

Nicobar Parakeet

The Nicobar Parakeet is another regional endemic associated with mature forests. Like many island parrots, it depends on old trees for nesting cavities and native fruits for food.

Protecting large tracts of evergreen forest is therefore essential for its long-term survival.

Nicobar Serpent Eagle

The Nicobar Serpent Eagle is a forest raptor that hunts reptiles, small mammals, and other prey beneath the forest canopy. Its restricted distribution makes it one of the island’s conservation priorities.

Photography Tip: Dense rainforest, rather than open grassland, defines birdwatching on Great Nicobar. Telephoto lenses, patience, and careful listening are often more valuable than long-distance visibility.

Reptiles and Marine Wildlife

Leatherback Sea Turtle

The beaches of Great Nicobar are internationally significant nesting sites for the Leatherback Sea Turtle, the largest living sea turtle.

Unlike hard-shelled turtles, leatherbacks have a flexible, leathery carapace that allows them to dive to remarkable depths in search of jellyfish. Females return to suitable beaches to lay eggs, making undisturbed nesting habitats especially important.

Saltwater Crocodile

The reserve also supports populations of the Saltwater Crocodile, the world’s largest living reptile.

These crocodiles inhabit estuaries, mangrove creeks, rivers, and coastal waters. As apex predators, they help maintain ecological balance within wetland ecosystems.

Visitors should always respect warning signs and avoid approaching river mouths or mangrove channels where crocodiles may be present.

Amphibians

Several amphibians found within the biosphere reserve are endemic to the Nicobar Islands. Although they receive less public attention than birds or marine turtles, amphibians are excellent indicators of environmental health because they are highly sensitive to changes in water quality and habitat conditions.

The reserve’s perennial streams, moist forests, and high rainfall create suitable conditions for these specialised species.

Notable Plant Diversity

Great Nicobar’s forests support hundreds of plant species, including flowering plants, ferns, gymnosperms, bryophytes, and lichens.

Among the notable species highlighted in the research brief are:

• Cyathea albosetacea, a tree fern
• Phalaenopsis speciosa, an orchid associated with tropical island forests

These plants contribute to the structural complexity of the rainforest and provide habitat for insects, birds, and other wildlife.

Flagship Wildlife of Great Nicobar

Endemic Species: Why Great Nicobar Is Unique

Many protected areas are rich in wildlife, but relatively few support such a high proportion of endemic species. According to the research brief, Great Nicobar Biosphere Reserve is home to numerous endemic mammals, birds, reptiles, and amphibians, making it one of India’s most important island ecosystems for conservation.

Because these species evolved in isolation, they are often highly specialised and less able to adapt to rapid environmental change. This is why habitat protection remains the foundation of conservation across the reserve.

Indigenous Communities and Human Presence

Great Nicobar is not an uninhabited wilderness. Indigenous communities have lived on the island for generations and form an integral part of its cultural and ecological landscape.

Shompen Community

The Shompen are an indigenous community traditionally associated with the island’s interior forests. The research brief emphasises presenting their relationship with the land respectfully and avoiding stereotypes or speculative claims.

Their presence highlights that conservation in Great Nicobar is not solely about protecting wildlife but also about recognising long-standing human connections to the landscape.

Nicobarese Community

The Nicobarese community is another indigenous group associated with the island. Traditionally linked with coastal settlements and marine resources, they contribute to the cultural diversity of the Nicobar archipelago.

Understanding both communities helps explain why the biosphere reserve includes transition zones where conservation and sustainable human use coexist.

Responsible Tourism Tip: Indigenous communities are not tourist attractions. Visitors should respect access restrictions, privacy, and local regulations, and should never attempt to enter restricted tribal areas without proper authorisation.

Part 4: Visiting Great Nicobar Biosphere Reserve

Can Tourists Visit Great Nicobar Biosphere Reserve?

Yes—but visitors should not expect Great Nicobar to function like a typical wildlife destination.

Unlike many Indian national parks that are designed around tourism, Great Nicobar Biosphere Reserve is first and foremost a conservation landscape. Large parts of the reserve are protected for ecological research, habitat conservation, and the welfare of indigenous communities. As a result, public access is far more limited than in mainland wildlife reserves.

For most travellers, careful planning and a realistic understanding of access restrictions are essential. The appeal of Great Nicobar lies in its ecological significance rather than conventional sightseeing opportunities.

Visitor Access at a Glance

The exact permissions required can change over time. Visitors should always rely on the latest information from the Andaman and Nicobar Administration before making travel plans.

Do Visitors Need Permits?

Yes. Great Nicobar is a regulated island, and access typically involves permits in addition to any travel formalities required for the Andaman and Nicobar Islands.

The research brief deliberately avoids listing detailed permit procedures because these may change. Instead, it recommends emphasising that visitors should verify current requirements with the relevant authorities before travelling.

Expert Tip: Never rely on outdated travel blogs for permit information. Administrative rules can change, particularly for ecologically sensitive islands.

Best Time to Visit

The research brief identifies this as an important planning question but avoids prescribing exact months without official support. In general, visitors should consider:

• Weather conditions
• Sea transport schedules
• Local administrative advisories
• Operational travel permissions

Because access depends on both environmental conditions and government regulations, flexibility is important when planning a visit.

What Kind of Experience Should You Expect?

Great Nicobar is not a destination where visitors arrive expecting frequent wildlife sightings or extensive tourist facilities.

Instead, travellers should expect:

• A remote island environment
• Limited tourism infrastructure
• Strong emphasis on conservation
• Restricted movement in sensitive areas
• Opportunities to appreciate intact tropical ecosystems rather than organised safari experiences

For many wildlife enthusiasts, simply understanding why these restrictions exist is part of the experience.

Field Note: The absence of mass tourism is one of the reasons Great Nicobar remains ecologically important. Responsible visitors should see restricted access as a conservation success rather than an inconvenience.

Responsible Tourism Guidelines

Visitors who receive permission to travel should follow low-impact practices throughout their visit.

Do

• Follow all permit conditions.
• Stay within authorised areas.
• Respect indigenous communities and their privacy.
• Carry back all non-biodegradable waste.
• Observe wildlife from a safe distance.
• Follow instructions issued by local authorities.

Don’t

• Attempt to enter tribal reserve areas.
• Disturb nesting beaches or wildlife.
• Remove shells, plants, or other natural materials.
• Feed wild animals.
• Fly drones where prohibited.
• Ignore local conservation regulations.

Why Great Nicobar Matters for Conservation

Great Nicobar is recognised internationally because it protects an exceptional concentration of biodiversity within a relatively small island landscape.

Several features contribute to its conservation importance:

• UNESCO Man and the Biosphere recognition
• Key Biodiversity Area (KBA) status
• Extensive tropical evergreen forests
• Important marine and coastal habitats
• High levels of endemic wildlife
• Presence of threatened species such as the Leatherback Sea Turtle and Dugong

Coastal Forests and Turtle Nesting Beaches

The reserve’s coastal forests do far more than provide scenic landscapes.

They:

• Stabilise shorelines
• Reduce coastal erosion
• Protect freshwater systems
• Support endemic wildlife
• Create suitable nesting conditions for marine turtles

Even relatively small disturbances to these habitats can have long-term ecological consequences because island ecosystems recover slowly.

Coral Reefs and Marine Ecosystems

The coral reefs surrounding Great Nicobar are closely linked with the island’s forests and coastal habitats.

Healthy reefs:

• Support marine biodiversity
• Protect shorelines from wave action
• Provide habitat for numerous fish and invertebrates
• Contribute to overall ecosystem resilience

The research brief also notes coral-related mitigation measures in discussions surrounding recent development proposals, highlighting the ecological importance of these marine habitats.

Conservation Challenges

Like many island ecosystems, Great Nicobar faces multiple conservation pressures.

The research brief identifies several major concerns:

Habitat Loss

Island species often occupy limited ranges, meaning habitat loss can affect entire populations.

Protecting continuous forest cover remains one of the reserve’s highest conservation priorities.

Invasive Species

Non-native plants and animals can compete with endemic wildlife for food and habitat. On isolated islands, invasive species frequently have greater impacts than they do on continental ecosystems.

Coastal Disturbance

Disturbance of beaches, mangroves, and coastal forests can affect nesting sea turtles, shorebirds, and other specialised wildlife that depend on these habitats.

Balancing Conservation and Development

The research brief highlights that recent discussions about Great Nicobar have largely focused on the proposed island development project. It recommends presenting this topic in a balanced manner by separating verified facts from opinions.

Verified facts include:

• The project has undergone environmental review.
• Environmental safeguards and mitigation measures have been proposed.
• The project has attracted scrutiny from conservation organisations, policymakers, and legal bodies because of its potential ecological implications.

Rather than allowing this debate to define the reserve, it is important to recognise that Great Nicobar’s ecological significance predates current development proposals by decades.

Expert Tip: When reading about Great Nicobar, distinguish between information describing the biosphere reserve itself and news relating to specific development projects. They are closely connected but not the same subject.

End of Part 4.

Part 5: Recent Developments, Common Mistakes, FAQs & Conclusion

Recent Developments: Understanding the Current Context

In recent years, Great Nicobar Biosphere Reserve has received increased public attention because of the proposed Great Nicobar Island Development Project. While this has brought the island into the national spotlight, it has also led to confusion between the biosphere reserve itself and the broader development proposal.

The research brief recommends treating these as related but distinct topics. The biosphere reserve is a long-established conservation landscape recognised for its biodiversity and ecological value, whereas the development project is a contemporary policy initiative that has undergone environmental review and continues to attract discussion among government agencies, conservationists, researchers, and legal bodies.

What Is Verified?

The following points are supported by the research brief:

• The development project has been subject to environmental assessment.
• Environmental safeguards and mitigation measures have been proposed.
• The project has generated debate regarding potential impacts on forests, wildlife, coral reefs, and coastal ecosystems.
• The issue has received attention from courts, government agencies, and conservation organisations.

For readers seeking current information, it is important to distinguish verified facts from opinions expressed by different stakeholders. The ecological importance of Great Nicobar extends well beyond the current development debate.

Practical Checklist for Visitors

If you plan to visit Great Nicobar, keep these points in mind:

✔ Verify current travel and permit requirements before departure.

✔ Respect all access restrictions and protected zones.

✔ Do not attempt to visit indigenous communities without authorisation.

✔ Carry reusable water bottles and minimise plastic waste.

✔ Observe wildlife without disturbing animals or nesting sites.

✔ Follow instructions issued by local authorities and conservation staff.

✔ Be prepared for limited tourism infrastructure compared with mainland destinations.

Common Mistakes to Avoid

Many misconceptions about Great Nicobar arise because of its unique conservation status. Avoid these common errors:

1. Assuming It Is a Typical Tourist Destination

Great Nicobar is managed primarily for conservation, not mass tourism. Visitor access is limited and carefully regulated.

2. Confusing the Biosphere Reserve with the National Parks

Campbell Bay National Park and Galathea National Park are protected areas within the larger Great Nicobar Biosphere Reserve. They are not separate biosphere reserves.

3. Treating the Entire Island as Open to Visitors

Many areas remain protected because of ecological sensitivity or the presence of indigenous communities. Public access is not unrestricted.

4. Assuming the Development Project Defines the Reserve

The biosphere reserve’s conservation value existed long before recent development proposals. Understanding its ecology requires looking beyond current headlines.

5. Underestimating Island Ecosystems

Island species often occupy very limited ranges. Even small disturbances can have lasting ecological consequences.
