Flora
The flora of Sundarbans Tiger Reserve is uniquely adapted to its mangrove ecosystem, making it a distinct and biodiverse habitat. Dominated by dense mangrove forests, the reserve features vegetation that thrives in saline and tidal conditions. The dominant tree species include Sundri (Heritiera fomes), Gewa (Excoecaria agallocha), Keora (Sonneratia apetala), and Golpata (Nypa fruticans), each adapted with features like stilt roots and pneumatophores to survive waterlogged soils. The reserve also supports various terrestrial and aquatic plants, such as medicinal herbs and salt-tolerant halophytes. This diverse flora provides essential habitats for wildlife, stabilises the delta region, and supports local communities through resources and livelihoods.
Fauna
The Sundarbans Tiger Reserve is a biodiversity hotspot renowned for its unique mangrove ecosystem. The Bengal tiger (Panthera tigris tigris) dominates the food chain, adept at navigating the reserve's intricate waterways. Key predators include the estuarine crocodile (Crocodylus porosus) and the Indian python (Python molurus). Herbivores like spotted deer (Axis axis), wild boar (Sus scrofa), and rhesus macaques (Macaca mulatta) maintain ecological balance. Bird enthusiasts can observe kingfishers, herons, and the endangered masked finfoot (Heliopais personata). The reserve’s rivers support Gangetic dolphins (Platanista gangetica), diverse fish, crabs, and mollusks, highlighting its critical role in global biodiversity and conservation efforts.
