The forest spans across the southern part of West Bengal in India and the southwestern part of Bangladesh, with about 60% of the forest lying within Bangladesh’s borders.
The Sundarban experiences a tropical monsoon climate, characterized by distinct wet and dry seasons. The region receives an average annual rainfall of 1,600-1,800 mm, primarily during the monsoon months of June to September. Temperatures range from 20°C to 36°C throughout the year, with high humidity levels. The unique climate supports the diverse ecosystem and contributes to the forest’s rich biodiversity.
The Sundarban’s geological landscape is a complex network of tidal waterways, mudflats, and small islands. The forest is constantly evolving due to the dynamic interplay of freshwater from rivers and saltwater from the Bay of Bengal. This interaction creates a unique brackish water environment, ideal for mangrove growth. The region’s geology is characterized by its low-lying terrain, with an average elevation of only 7 meters above sea level. This distinctive landscape, shaped by tidal action and sediment deposition, plays a crucial role in supporting the mangrove ecosystem and its inhabitants.
The Sundarban Mangrove Forest boasts an impressive array of mangrove species, with over 30 true mangroves identified. The most dominant species include Sundari (Heritiera fomes), from which the forest derives its name, Gewa (Excoecaria agallocha), and Keora (Sonneratia apetala). These species form the backbone of the forest’s ecosystem, providing crucial habitats for diverse wildlife.
Mangroves in the Sundarbans have evolved remarkable adaptations to thrive in their saline environment. Many species possess pneumatophores, specialized aerial roots that emerge from the mud to facilitate oxygen uptake. Others, like the Avicennia species, have developed salt-excreting glands on their leaves to regulate internal salt concentrations. The unique viviparous reproduction of some mangroves, where seeds germinate while still attached to the parent tree, ensures successful propagation in the challenging tidal environment.
The Sundarban’s flora includes numerous plants with medicinal properties. The bark of the Sundari tree is used to treat gastrointestinal disorders, while the leaves of the Nipa palm (Nypa fruticans) are employed in traditional remedies for asthma. The pneumatophores of Sonneratia species are known for their analgesic properties. These medicinal plants not only contribute to local healthcare practices but also hold potential for modern pharmaceutical research.
Mangrove vegetation plays a crucial role in maintaining the ecological balance of the Sundarbans. These plants act as natural barriers against cyclones and storm surges, protecting coastal communities. Their intricate root systems provide nursery grounds for various fish species, supporting the region’s fisheries. Additionally, mangroves are efficient carbon sinks, sequestering significant amounts of atmospheric CO2 and mitigating climate change impacts. The forest’s vegetation also prevents soil erosion, maintaining the delicate balance of the Ganges delta ecosystem.
The Sundarban Mangrove Forest is synonymous with the majestic Royal Bengal Tiger, the apex predator of this unique ecosystem. These powerful cats have adapted remarkably to the challenging mangrove environment, developing exceptional swimming abilities and a salt-tolerant physiology. Their presence is a testament to the health and biodiversity of the Sundarbans.
The waterways of the Sundarbans teem with diverse aquatic life. Over 120 species of fish, including the iconic hilsa and the peculiar mudskipper, inhabit these brackish waters. Crustaceans like mud crabs and prawns play crucial roles in the ecosystem, while amphibians such as the green frog and cricket frog thrive in this unique habitat.

The Sundarbans boast an impressive array of avian species, with over 260 bird species recorded. Resident birds like kingfishers, herons, and egrets are joined by migratory species during winter. The mangrove forest provides essential roosting and nesting sites for these birds, contributing significantly to the region’s biodiversity.
Reptiles are well-represented in the Sundarbans, with species like the saltwater crocodile, water monitor lizard, and various snake species playing vital roles in maintaining ecological balance. These reptiles are crucial for controlling prey populations and contributing to nutrient cycling within the mangrove ecosystem.
The Sundarbans harbor several endangered species, including the Irrawaddy dolphin and the masked finfoot. Conservation efforts focus on protecting these vulnerable species and their habitats. Initiatives include habitat restoration, anti-poaching measures, and community-based conservation programs to ensure the long-term survival of the Sundarbans’ unique fauna.
The Sundarban Mangrove Forest hosts a complex web of predator-prey relationships, with the Bengal tiger at the apex. These majestic predators primarily hunt spotted deer, wild boars, and occasionally smaller prey like monkeys. The estuarine crocodile, another formidable predator, preys on fish, crabs, and even unwary mammals near the water’s edge. In the aquatic realm, various shark species and larger fish dominate the food chain, feeding on smaller fish and crustaceans.
Symbiotic relationships abound in the Sundarbans, contributing to the ecosystem’s resilience. Mangrove trees provide shelter and nesting sites for numerous bird species, which in turn help disperse seeds and control insect populations. Algae and barnacles form mutualistic associations with mangrove roots, gaining protection while enhancing nutrient uptake for the trees.
The Sundarban’s nutrient cycling is a marvel of efficiency. Fallen leaves and organic matter decompose in the mudflats, enriching the soil and supporting a diverse community of microorganisms. These nutrients are then absorbed by mangrove roots and cycled through the food web. The tidal action plays a crucial role, distributing nutrients across the ecosystem and supporting the rich biodiversity of the Sundarbans.
