সুন্দরবনের বন্যপ্রাণী (Wildlife of The Sundarbans)_POJF_EP-323

Thanks to tropical geo-positioning, Bangladesh is highly rich with floral and faunal resources. Our mixed evergreen forests, deciduous forests, grassland forests and wetlands are the main sanctuaries of this diverse flora and fauna. These diverse forests have enriched the biodiversity of this country. The Sundarbans is the most unique and diverse among the forests of Bangladesh. Sundarbans is the largest singular mangrove forest of the world. Salinity of soil & water and tidal effects have lent the flora of Sundarbans a distinct characteristic. With ecosystems of unique characteristics, Sundarbans is the safe haven for a diverse wildlife. A variety of wildlife species including birds, mammals, amphibians and reptiles are found here. Notable among these are the Bengal Tiger, Fishing Cat, Jungle Cat, Spotted Deer, Barking Deer, Rhesus Monkey, Asian small-clawed Otter, King Cobra, Boar, and different species of Bird. Among aquatic biodiversity notable are the Salt-water Crocodile, Northern River Terrapin, River Dolphins and Dolphins. Among the herbivorous mammals of Sundarbans are Spotted Deer, Barking Deer, Wild boar and Rhesus Monkey. The Mangrove Apple fruit and leaves are favorite food of Spotted Deer. Rhesus Monkey is the only monkey species in this forest. Although tree dwellers, they often venture on the ground for food. Globally endangered, Bangladesh's national animal, the Bengal Tiger mainly inhabits the deep forests of Sundarbans. Though once available in all forests of Bangladesh, at present Tiger exists in the Sundarbans only. Another mammal of Sundarbans is the Asian small-clawed otter. In low tide, Otter with small claws can be seen on the muddy slopes of Sundarbans’ canals. Otters lead a social life. They mainly sustain on fish. Among aquatic mammals, Ganges River Dolphins are found in Sundarbans’ Rivers. This aquatic mammal is quite vital for our aquatic ecosystem. In species diversity Birds have the largest number in Sundarbans. Kingfisher is prominent among the birds. About nine species of Kingfisher are seen here. Among them, Ruddy Kingfisher is quite rare and mostly found in Sundarbans. Ruddy Kingfisher has reddish head and back and bright red beak. They mainly roam around Sundarbans’ wetlands and canal. A critically endangered bird of Bangladesh, the Masked Finfoot, is only found in Sundarbans. Similar to domestic duck in size, it has brown body and bright yellow beak. Foraging in mud or water, it sustains on fish, crab, etc. Also, the aquatic bird Lesser Adjutant is seen here. Its throat is featherless and head bald. It feeds on fish with its long and powerful beak. Various Bird species, including some Raptor birds, are seen in this forest. The Sundarbans is a prominent habitat of reptiles and amphibians. Once, three crocodile species inhabited Sundarbans. These are, Mugger Crocodile, Salt Water Crocodile and Gharial. Although, Mugger Crocodile and Gharial have declined for various reasons, the Salt Water Crocodile still sustains. One of our critically endangered reptile, the Northern River Terrapin still survive only in the wild in Sundarbans, in small numbers. A number of venomous and non-venomous snakes, including Python, King Cobra, Monocled Cobra, and Dog-faced Water Snake inhabit this forest. Also, there are ten Frog species. Prominent among them are Crab eating Frogs and Green Pond Frog. Green Pond Frog is one of the largest frogs of Bangladesh. They spend almost their whole life in wetlands. They commonly roam the floating aquatic plants. Their green backs camouflage them among the aquatic plants. A bountiful reservoir of biodiversity, the Sundarbans was recognized as a natural World Heritage Site by UNESCO in 1997. However, this natural mangrove forest is being damaged due to various natural disasters and human activities. Now, it is threatening the existence of its various aquatic and terrestrial wildlife. At present, most wildlife here are endangered due to river pollution, arbitrary forest resource extraction, illegal poaching, etc. Therefore, it is necessary to take initiatives and create public awareness to conserve the wildlife of Sundarbans. Only then, the diverse wildlife of our natural World Heritage Sundarbans will sustain.
