History and Establishment
Arial Island Wildlife Sanctuary was officially notified as a wildlife sanctuary in 1987. The decision to designate this area as a sanctuary grew out of recognition of its unique ecosystems — not just terrestrial forest but significant marine and coastal ecosystems as well — including mangroves, coral reefs, and island vegetation.
Over the years, the Sanctuary has evolved under the management of the Andaman & Nicobar Forest Department, with incremental efforts to protect its flora, fauna, and marine life. Policies governing sanctuaries in India such as the Wildlife Protection Act, local conservation programmes, and marine protection efforts have influenced its trajectory.
Although specific management plans are less publicised compared to some larger sanctuaries, Arial Island Wildlife Sanctuary remains part of the regional network of biodiversity conservation in the Andamans.

Geography and Climate
Geography
- Location: Arial Island Wildlife Sanctuary is located in Arial Bay, part of the Andaman Islands in India. It’s administered under the North & Middle Andaman Administrative.
- Islands Included: It comprises several islands within the Arial Bay group — such as Smith Island, Chatham Island, Ross Island, Ox Island, etc. The largest inhabited island among them is Smith Island.
- Area: The Sanctuary covers a small area — approximately 0.05 square kilometers (around 50,000 square meters).
- Habitat Types: The sanctuary includes coral reefs, tidal mangroves, vegetated islands, evergreen forest zones, and open sea. This mix of aquatic and terrestrial habitats gives it high ecological value.
Climate
- General Climate Type: Tropical-marine climate, typical of the Andaman Islands. There’s strong humidity, warm temperatures year-round, moderated by sea breezes.
- Temperature: Average temperatures stay moderately high, with less extreme variation than many inland areas. The proximity to the sea keeps the heat somewhat tempered.
- Rainfall: Significant rainfall occurs especially during the monsoon season. Rainfall patterns affect visibility, sea conditions (for coral reefs), and trekking or boat access.
- Best Climate Windows: The period from November to April tends to be the most favorable — dry, more predictable sea conditions, less rainfall, better for both terrestrial and marine wildlife observation.
Flora of Arial Island Wildlife Sanctuary
Flora plays a critical role in shaping the sanctuary’s ecosystems, particularly because many species are adapted to coastal, island, and mangrove habitats.
- Mangroves: Mangrove trees and shrubs dominate much of the tidal regions. These are vital for shore stabilization, preventing erosion, and serving as nurseries for marine life.
- Evergreen Forests: Patches of Andaman evergreen forest exist on vegetated islands, with species adapted to humid, warm, and relatively stable temperature conditions.
- Coastal Vegetation: Near beaches and rocky shores, salt-tolerant species, including certain palms, beach grasses, and shrubs adapted to spray and saline soils, are found.
- Coral Reef Flora (Algae, Seagrass): In the marine portion, algae, seaweeds, and possibly seagrass beds are present. These are integral to reef health and fish populations.
- Endemic Plant Species: Though detailed published lists are sparse, plant species native to the Andamans, some endemic, are present — especially in the forested zones and mangrove edges.
Because of these varied vegetation zones — from mangroves to evergreen forest to coastal scrub — the sanctuary supports a high level of ecological niches.

Fauna of Arial Island Wildlife Sanctuary
This section covers the range of animals found there, from large mammals to marine life, emphasizing both diversity and rarity.
Mammals
- Fruit Bats, Andaman Shrews, Rats: Small mammalian species adapted to forested and island life.
- Crab-eating Macaque and Wild Boar: More common mammals that can adapt to both forest and coastal fringe habitats.
Large mammals (if present) are less documented, due largely to the sanctuary’s small size and island geography limiting habitat for bigger species.
Birds
Arial Island is notable for its bird life:
- Resident Species: Species that live year-round in the Andamans, adapted to island forest, mangrove, coastal, and reef edges.
- Migratory Birds: Birds that visit seasonally, especially during northern hemisphere winters, making use of islands and coasts for rest. The period between November and April is favourable for bird watchers.
Some of the species recorded include:
- Nicobar Pigeon
- Andaman Coucal
- Andaman Crake
- Serpent-eagle
- White-headed Starling etc.
Reptiles and Amphibians
- Sea Turtles: Green sea turtle, Hawksbill turtle are among marine reptiles likely in or near the sanctuary’s reefs and coastal waters.
- Monitor Lizards, other Island Reptiles: Andaman Water Monitor, and other reptiles that thrive in island forest and mangrove habitats are present.
Amphibians are less documented in public sources, but tropical islands like this often harbor frogs and other amphibians in forest floor litter, temporary water bodies.
Marine Life
Given the reef and open sea components:
- Coral reefs host diverse corals, reef fish species, possibly invertebrates like molluscs, crustaceans, etc.
- Mangroves shelter juvenile fish, crustaceans, and provide feeding grounds for birds and mammals.
- Sea turtles use reefs or nearby beaches for nesting or feeding.
Conservation Efforts
Conservation for Arial Island Wildlife Sanctuary includes several dimensions: legal protection, habitat protection, species monitoring, and managing human impacts.
- Legal Status: Since being notified as a Wildlife Sanctuary in 1987, same legal protections under the Wildlife Protection Act apply.
- Marine & Coastal Protection: Because reef and mangrove ecosystems are vulnerable to pollution, climate change, and illegal fishing, protecting coastal margins is essential. Restrictions on fishing, marine access, and development near mangroves are likely part of management.
- Species Monitoring: Monitoring of key species (birds, turtles, reef fish) helps assess health of ecosystems and detect threats. Migratory birds, marine turtles are particularly crucial indicators.
- Habitat Restoration: Where mangroves are degraded, replanting may be undertaken. Rehabilitating coral reef areas (if damaged) through coral gardening or reef protection zones may be part of conservation strategies.
- Community Engagement and Awareness: Local community involvement is critical. Education, awareness campaigns, sustainable livelihoods, eco-tourism can help align conservation with people’s welfare.
- Enforcement: Patrols, restrictions, and legal action against poaching, logging, illegal fishing, or other unauthorized activity are part of effective conservation.
