Koshi Tappu Wildlife Reserve
Koshi
Koshi Tappu Wildlife Reserve is a significant protected wetland area located in the Terai region of eastern Nepal, covering 176 square kilometers across Sunsari, Saptari, and Udayapur districts. Established in 1976 and designated as a Ramsar site in 1987, it features extensive reed beds, freshwater marshes, and mixed deciduous riverine forests. The reserve is renowned for harboring Nepal's last remaining herd of wild water buffalo, with a thriving population of over 400 individuals. Its diverse habitats support over 485 bird species, including rare and notable birds such as the Bengal florican, large adjutant stork, and Pallas’s fish eagle. The wetlands also shelter a variety of mammals including Asian elephants, spotted deer, and smooth-coated otters, as well as aquatic species like gharial and mugger crocodiles. The floodplain ecosystem is maintained by the annual flooding of the Sapta Koshi River, which sustains the grasslands and marshes. Besides its ecological importance, the reserve faces challenges from human-wildlife conflict and illegal resource use. Koshi Tappu offers a unique opportunity for wildlife observation and conservation awareness in Nepal's rich natural heritage.
