Mangroves in Port Blair: Andaman’s Tropical Coastal Biodiversity

Port Blair, the capital of the Andaman and Nicobar Islands, is surrounded by some of the richest and most diverse mangrove ecosystems in India.

These mangroves, spread across the islands, are ecological treasures that protect the coast, sustain biodiversity, and provide livelihood opportunities for local communities.

As tropical guardians of Andaman’s coastline, mangroves play a crucial role in maintaining the environmental balance and combating climate change.

Historical and Cultural Significance

Mangroves in the Andaman and Nicobar Islands have supported indigenous tribes and coastal communities for centuries.

Historically, these ecosystems provided food, wood, and medicinal plants to sustain the local population.

Post-independence, as the islands developed into strategic ports, mangroves served as natural shields against tidal waves and storms.

Today, Port Blair’s mangroves are recognized for their ecological importance and are part of the World Network of Biosphere Reserves.

Ecological Importance

1. Cyclone and Tsunami Mitigation

Port Blair’s mangroves act as natural barriers, absorbing tidal surges and reducing the impact of cyclones and tsunamis. During the 2004 Indian Ocean Tsunami, these mangroves significantly minimized damage in areas where they were intact.

2. Biodiversity Hotspot

The mangroves are home to a wide array of species, including mudskippers, fiddler crabs, and saltwater crocodiles. They also attract migratory birds like herons and egrets, making them vital for avian biodiversity.

3. Carbon Sequestration

Mangroves in Port Blair are excellent carbon sinks, storing up to 10 times more carbon per hectare than terrestrial forests. This makes them critical in the global fight against climate change.

4. Water Filtration

Mangroves filter sediments and pollutants from the water, ensuring healthier ecosystems for marine life in the surrounding seas.

5. Fisheries and Livelihoods

Mangroves provide breeding grounds for fish, prawns, and crabs, sustaining the livelihoods of local fishing communities.

Fun Facts About Port Blair’s Mangroves

  • Crocodile Central: The mangroves are a haven for the elusive saltwater crocodile, one of the largest reptile species in the world.
  • Unique Root Structures: The mangroves in Andaman are famous for their stilt roots, which adapt to waterlogged soils and provide stability during tidal changes.
  • Avicennia and Rhizophora Dominance: These two mangrove species dominate the ecosystem, thriving in saline waters and showcasing nature’s adaptability.

Environmental Challenges

  1. Coastal Development Port Blair’s expanding infrastructure and tourism industry pose a significant threat to mangrove ecosystems, leading to habitat fragmentation and destruction.

  2. Pollution Plastic waste, untreated sewage, and oil spills in the Andaman seas degrade mangrove health, affecting flora and fauna.

  3. Climate Change Rising sea levels and increasing salinity due to climate change threaten mangrove survival and regeneration.

  4. Overharvesting Unregulated harvesting of mangrove resources like wood and crabs has led to ecosystem imbalances.
